2dB). The distortion threshold was exceeded above this SPL. The vocals are more in the foreground, but the sound isn’t flat or static. The MB42X feature silk dome tweeters and 4-inch carbon fiber woofers. As for bass… well, there’s really not much there. MB42comes only in … But, again, since this region is down so low relative to the treble region, it doesn’t really help. Mic placed about 0.50 inches - relative to the baffle - from each drive unit and port. I have provided both an absolute SPL version as well as a normalized version of both the horizontal and vertical sound fields. Power Handling: 75 W. Sensitivity: 85dB. Norah Jones “Tell Yer Mama”: Mechanical noise… Tinsel lead slap? This is a review of the older Micca MB42x, Click here to go to the updated review of the MB42x.If you just want to know more about the MB42x, this review is a pretty good read which is why I left it up, but it's not indicative of the sound of … I honestly didn’t believe them until I tested the MB42X by Micca myself. However, note: the 80Hz signal is a “brick wall” and does not emulate a typical 80Hz HPF slope of 24dB/octave. The dashed red line is for reference and shows the 1% distortion mark (but has no bearing on pass/fail). The distortion is high. I made it through about 7 songs before I just stopped. In my experience, all these factors play in to how the listener “connects” with the system. If you question the performance and can demo the speakers in your own home, I suggest you take advantage of the opportunity. If you have a high-Q resonance at 450Hz the 300Hz resolution data will not show this resonance because the frequency resolution only has a data point at 300Hz and 600Hz; skipping right over the 450Hz. System Components. So Polk Audio T15, while being a cheaper option, tends to get more favorable ⭐ reviews than the $90 Micca MB42X, as seen on the chart below. The blue shaded area represents the ±3dB response window from my calculated mean SPL value. Crossover Channel Qty. Tweeter: 0.75-Inch Silk Dome. If you want help understanding what this data means, watch the video below. Harmonic Distortion and Compression are provided at varying levels to get an idea of what happens as the voltage into the speaker is increased and overall output volume increases. Both speakers have 4.5″ woofers made of Kevlar. The above data can be summed up by looking at the tables above but is provided here again: Thiele-Small and Large Signal Analysis: copyright © 2019 gethugothemes all right reserved, Klippel’s In-Situ Room Compensation (ISC) module, Linear Lumped Parameter Measurement Module, Klippel’s Training 1 - Linear Lumped Parameter Measurement tutorial, Klippel’s Training 3 - Loudspeaker Nonlinearities tutorial, Songs from the Big Chair (2014 Deluxe Edition - Disc 1), Mark Keali’i Ho’omalu and Kamehameha Schools Children’s Chorus. I would strongly suggest using an EQ to help with the response. Micca has been a friend to budget audiophiles for a while now, releasing a series of affordable, compact and sometimes oddball speakers that do enough things right to catch audiophiles’ attention. Now that you understand my motives, let’s get started with the review. Both are currently free software. The response curve of the Micca MB42X MKIII is extremely non-linear; exhibiting as a wholly recessed midrange, a prominent bump between 1-2kHz and poor linearity above 4kHz. 2 speakers. But… it’s close enough. The impedance of a speaker varies depending on the frequency being played, and it is normal for most 8ohm rated speakers have impedance that dip as low as 4ohms or even lower. The result of painstaking fine tuning through balanced application of science and art, the crossover yields a transformed sound signature … My Micca MB42X-C is within the return window, I'm thinking of return the Micca and getting the matching Dayton MK442. frequency response graphs, CSD waterfall plots, subjective gear reviews. Components: Oppo BDP-103 playing music off my thumb drive feeding signal via HDMI to a Denon AVR-X4000 which then feeds in to a refurbished Adcom GFA-545 for power. Not simply because of subjective performance. Meaning, if a speaker is ideal and you tell your stereo to increase by 6dB by turning the volume knob +6dB, the output will increase by 6dB. With the frequency response range of 60Hz-20kHz, they offer a smooth and balanced performance. are all based on a 2.83 volts RMS logarithmic sweep at 1 meter to meet the standard sensitivity measurement spec. Note: This is not a standard merge of nearfield and farfield nor a merge of ground-plane and farfield. In the nearfield listening, the output was about the same level because of distortion limitations; I didn’t like them above 90dB. As you will see below, my music selection did a great job at providing enough range for me to identify the issues that readily appear in the data. Notice how well it matches the predicted in-room response. This speaker does not have that at all. passive. The MB42X is a very reasonably priced model, so you don’t have to drain your bank account in order to enjoy good sound quality. The Police “Wrapped Around Your Finger”: There’s nothing in the bassline below about 140Hz. The compression is high. The Micca MB42X is a pair of compact speakers featuring a 4-inch carbon fiber woofer and a 0.75-inch silk-dome tweeter. If there is a single set of data to use in your purchase decision, this is probably it. Midbass was lacking emphasis. The MB42X is a great choice for audiophiles who crave thunderous bass. https://youtu.be/iCjJufvW0IA. It definitely feels fine for the price and looks like it can last for many years. And, finally, here is a great video of Dr. Toole discussing the use of measurements to quantify in-room performance. The MB42X cabinets are somehow bulky for bookshelf speakers, with 6 in width, 7 inches in depth, and 10 inches in … Buy the Neumi BS5 if you’re looking for a budget set of bookshelf speakers. Typical merged responses still suffer low resolution in the midrange where the response is merged due to the necessity of windowing the impulse response to remove reflections. Before I dive in to the subjective feedback let me first give you the layout of my room…. On the specs side, you get an 85 dB sensitivity and 60Hz-20kHz frequency response. Thanks to the ISC module, the data I am providing here is higher resolution (~30Hz resolution) than an average person can provide without access to an anechoic chamber or the like. In a poll I found most listen to music in this range. I'm wondering if anyone has any experience with the Dayton MK442 as a center (I know people like to purchase as pairs and use them as L/R's). Klippel’s In-Situ Room Compensation (ISC) module is then used with the ground plane measurement to provide a ‘reference’ curve to the 4-pi measurement which then corrects for the room’s influence and allows me to generate a reflection-free far-field response from an indoors measurement. Note, again, the volume wasn’t that loud. Note: I don’t generally audition speakers with the typical “audiophile” music. Micca Mb42 has a filtering capacitor on its tweeters. The compression threshold was exceeded above this SPL. Using Klippel’s Distortion Analyzer 2, Linear Lumped Parameter Measurement Module, Pro Driver Stand and provided Panasonic ANR12821 Laser along with Klippel’s Training 1 - Linear Lumped Parameter Measurement tutorial, I measured this drive unit’s impedance and small-signal parameters. The null at the transistion around 4000Hz looks less severe than it is because I am only have data for one-third octave measurements. 75" silk dome - crossover: 12dB/Octave - enclosure: ported - frequency response: 60Hz-20kHz - impedance: 4-8 ohms - Sensitivity: 85dB 1W/1M - power handling: 75 watts (each) - dimensions: 9. I said it. And with a bookshelf speaker like this, it should absolutely be crossed above 100Hz to limit any playback near the Fs of 87Hz. It’s not bad, but not great either. And as a bonus, Micca MB42X speakerslook stylish too. Is it the room, the actual speaker itself, my brain, or a combination? Looking back at the data, this is the only area in the response that is linear within about 1/2-Octave above/below. I also love the matte finish and the magnetic grill. All of these parameters translate to a speaker that needs to large enclosure (so the Qtc will not be any larger; as the Qts itself is already relatively high), high low cutoff point (due to high Fs) and low sensitivity (even though the on-axis average SPL is ~ 85.5dB, the SPL in the bass region is in the low 80’s). This measurement follows the IEC 60268-21 Long Term SPL protocol, per Klippel’s template, as such: Each voltage test is 1 minute long (hence, the “Long Term” nomenclature). The MB42X bookshelf speaker from Micca inherits the looks of its predecessor, the MB42s model, with a simple ebony laminated wood grain design that allows it to blend into any room or décor. You would need a resolution of at least a half the width of the Q-factor; generally, 20Hz is adequate. With the frequency response range of 60Hz-20kHz, they offer a smooth and balanced performance. Too objective for subjectivists; too subjective for objectivsts. The Micca MB42x MKIII is a terrible speaker if you intend to listen to it as a budget audiophile speaker (or anything resembling that). The difference in the midrange to upper-midrange/low-treble is nearly 5dB and then a 3dB dip from low-treble to upper-treble above 7kHz. Such is the case in my evaluations. Micca lists these “Feature Highlights” on their site: That’s a big “no” to every-single-one of the above “features”. Audioholics has a great writeup on what these data mean (link here) and there is no sense in me trying to re-invent the wheel so I will reference you to them for further discussion. Multitone distortion testing. I purchased this speaker to compare against my recently reviewed Neumi BS5 (link here). Frequency Response of the Micca MB42Xand the Pioneer BS22 The similarities between the speaker responses might arise from the fact that there are significant similarities in their construction. From this you can determine how much absorption you need and where to place it to help remedy strong dips from the reflection(s). The low-level voltage version is standard because it ensures the speaker/driver is in linear operating range. 2-way. The bass was lacking because of the small woofer, and the treble had a … At this point I decided to move closer to see if listening in the nearfield would help (spoiler: it didn’t). All this result in a more open, dynamic, clean, and balanced sound, and numerous customer reviews prove it. The Pioneer BS22 and Micca MB42X both use dome tweeters. I listened to these speakers and made my subjective notes before I started measuring objectively. The speaker has a 4-inch woofer that is made from carbon fiber that helps to deliver rich bass sound. The distortion is high. Below are both the horizontal and vertical response over a limited window (90° horizontal, ±40° vertical). Since many will likely use this with a PC. Well, I’d be remiss for not delving in to that a little bit here. Plus, the rear port would be blocked killing the low end contribution it provides. Dimensions (inches): 9.5 x 5.8 x 6.5. Generally speaking, higher sensitivity speakers (like pro-audio speakers with 100dBSPL @ 2.83v/1m spec) suffer relatively no compression while lower sensitivity speakers (low 80’s dBSPL @ 2.83v/1m) suffer more compression. When used without a subwoofer, these speakers might sound not rich enough to some users. I purchased my sample from Amazon and it cost US $149 including Prime shipping. Below are the results. Frequency Response. It’s rare I have a mid/woofer be limited in excursion due to inductance.

Here’s the Neumi via my Amazon link again, if you want to buy them through my affiliate link and help the site out: If you like what you see here and want to help me keep it going, you can donate via the PayPal Contribute button at the bottom of each page. In the below results I provide the summarized table as well as the data showing how/why this SPL was deemed to be the maximum. In short, the CEA-2034 graphic below takes all the response measurements (horizontal and vertical) and applies weighting and averaging to sub-sets and can help provide an (accurate) prediction of the response in a typical room. The volume controls and the power button are placed in the back, which might be inconvenient. Unless otherwise noted, all the data below was captured using Klippel Distortion Analyzer 2 and Klippel modules (TRF, DIS, LPM, ISC to name a few). Distortion is very high below 200Hz with greater than 5% THD at typical listening levels. The “mean spl” values associated with each voltage provided in the legend is based on a calculation of expected volume assuming linear volume at the 300-3kHz region. There’s truly nothing positive I can say about this speaker. Max SPL for 20Hz to 20kHz is approximately 88dB @ 1 meter. And here is the nearfield setup (with the lawn chair in all its glory). Portugal The Man’s “Feel It Still”: The only song that had a positive attribute which was around about 800Hz which sounded the most natural so far. The Micca MB42x MKIII is a terrible speaker if you intend to listen to it as a budget audiophile speaker (or anything resembling that). No bass below ~160hz. This speaker also seems to be the favorite of youtube bloggers, helped partly by generous seeding of … And below is the Predicted In-Room response compared to a general Target curve equaling -1dB/octave. Above this, the distortion is anywhere from 2-3% THD in the midrange at these same listening levels. This results in a very “hollow” sound in the midrange and rather “forward” sounding presence region followed by a lack of upper end detail and sense of space (also thanks to the increasing directivity of the tweeter). Enclosure: Rear ported, matte black vinyl. If you can help by chipping in, I would truly appreciate it. The red line shows the final measurement where either distortion and/or compression failed. I used Room EQ Wizard (REW) and my calibrated MiniDSP UMIK-1 to get the volume on my AVR relative to what the actual measured SPL was in the MLP (~11 feet from the speakers). Micca MB42X The Micca MB42X are small, elegant, and impressive bookshelf speakers that belong to a more affordable category of audio speakers. Applying both will provide a good idea of the limitations if you were to want to run a speaker full range vs using one with a typical 80Hz HPF. Red = MLP Average (average response in the head area at the main listening position), Green = Front Row Average (average across front 3 seats in my home theater), Blue = Predicted In-Room Response from the data, The speaker was aimed on-axis with the vertical listening axis between the mid and tweeter per. But because of other factors such as aesthetics, pride of ownership, etc. The midrange exhibits a trough centered on ~300Hz. I even went so far as to use my Dayton DATs to sweep both speakers to make sure the impedance curves matched because I thought maybe one of them was damaged but that wasn’t the case. It suffers extreme non-linearity and high distortion. Micca MB42X Bookshelf Speakers with 4-Inch Carbon Fiber Woofer and Silk Dome Tweeter (Black, Pair) 4.6 out of 5 stars 3,835 $89.99 $ 89 . A spectrogram is an alternate way to view this full set of data. The Micca MB42X maximum power is 75 watts per speaker. Placing these speakers near a wall would help the midrange out but in doing so you just boost the overall response; meaning you also boost the trough in the midrange and the high-Q midbass bump. Whether you want to listen to music on your PC or love watching movies in your living room using your home theatre, this model will allow you to enjoy every moment of that. Micca MB42x Bookshelf Speakers. The MB42X … But on the other hand, Mb42x has an enhanced crossover section. Additionally, the MB42X utilizes a highly optimized 9-element crossover with full 18dB/octave* alignment and compensation network. Too objective for subjectivists; too subjective for objectivsts. Micca Audio is a Chinese manufacturer of both passive and active loudspeaker products; the upstart brand also offers power amplifiers, digital media players, and other accessories. I try to do a few listening sessions over a couple days so I can give my ears a break and come back “fresh”. Nominal Impedance. This result indicates the mid/woofer will have a very high level of mid-to-upper frequency distortion if the cone is asked to play content near Fs due to high inductance. Both are currently free software. What really impressed me about these speakers was the crispiness of the sound (even at highs) and a deep bass. Below are the nonlinear results. You may ask just how useful the above prediction is. Ground plane measurements are perfect for this but are subject to aiming/ground absorption (grass) and related issues above 400Hz. Let’s look at the measured in-room response I captured using my UMIK-1 and REW. Full response (20Hz - 20kHz with the angles from 0° to ±180°) with absolute SPL values, Full, “normalized” response (20Hz - 20kHz with the angles from 0° to ±180°) with SPL values relative to the 0-degree axis, Rated maximum sound pressure according IEC 60268-21 §18.4, Using broadband multi-tone stimulus according §8.4, Stimulus time = 60 s Excitation time + Preloops according §18.4.1, -20dB Distortion relative to the fundamental, -3dB compression relative to the reference (1V) measurement, First with a 20Hz to 20kHz multitone signal, Second with a limited 80Hz to 20kHz signal. Micca MB42X-C Center Channel Speaker ... what really sets this option from Polk apart is its performance tuned rear firing bass port that enhances the low-range frequency response … Nearly 70 measurements in total are represented in my data. The speaker’s F3 point (the frequency at which the response has fallen 3dB relative to the mean SPL) is 116Hz and the F10 (the frequency at which the response has fallen by 10dB relative to the mean SPL) is 65Hz. The MB42X impresses with its powerful picture projection, it’s easy to mistake the speakers for a … Most of the data was exported to a text file and then graphed using my own MATLAB scripts in order to present the data in a specific way I prefer. The response curve of the Micca MB42X MKIII is extremely non-linear; exhibiting as a wholly recessed midrange, a prominent bump between 1-2kHz and poor linearity above 4kHz. The frequency response rolls off over 16k significantly, while there are some spikes and dips in the lower ranges from 128 Hz to 800 Hz. The Neumi is the same price as these Micca speakers and the Neumi performance is leagues better than the Micca. Featuring the range of 60Hz-20kHz, such frequency response allows for a rather balanced sound. The Micca MB42X has less variability on the high end than the Dayton B652, which will ultimately sound better for vocals and most instruments. The Micca MB42 is one of the most purchased bookshelf speakers up to date. Well, looking at the data we see a big trough smack in the midrange at about 300Hz. Here’s the rundown of my subjective notes and where it fits with objective: Overall?…. 99 Micca RB42-C Center Channel Bookshelf Speaker with 4-Inch Woofers and Silk Tweeter (Dark Walnut, Each) 4.8 out of 5 stars 82 Now, another thing I want to point out is the frequency response of these MB42X speakers by Micca. The measurement below provides the frequency response at the reference measurement axis - also known as the 0-degree axis or “on axis” plane - in this measurement condition was situated at the ribbon. The veneer finish of SX6made an average impression on me. I varied it between 85-90dB, occasionally going up to the mid 90’s to see what the output capability was. That means a data point every 300Hz. The reason for the two measurements is because it is unfair to expect a small bookshelf speaker to extend low in frequency. The voltage just before this is used to help determine the maximum SPL. 5" (D) Micca RB42 Review - These are the brand new Micca RB42 mini bookshelf speakers. For the size of the speakers, the bass works really well. Amplification Type. The normalization simply means that I took the difference of the on-axis response and compared the other axes’ measurements to the on-axis response which gives the viewer a good idea of the speaker performance, relative to the on-axis response, as you move off-axis. I don’t typically listen to “audiophile” music because I just don’t enjoy it. There. Chinese audio brands receive scant attention from the audiophile press, but with affordable products like the Micca Audio RB42, that is already starting to change. They can offer you a more than decent performance and a nice, elegant appearance. Just “there”. These Micca speakers are a perfect and cheap bookshelf speakers under $100 for the home. Sausalito Audio also has a good write-up on these curves here. But below about 1kHz it strays vastly from that mean and gets as low as 80dB at 300Hz. frequency response graphs, CSD waterfall plots, subjective gear reviews. Max SPL for 80Hz to 20kHz is approximately 100dB @ 1 meter. The B652 is louder, but no flatter, on the low end. One of the things I absolutely need to mention in my review is the build quality of Micca speakers. There’s truly nothing positive I can say about this speaker. The Micca MB42X are small, elegant, and impressive bookshelf speakers that belong to a more affordable category of audio speakers. Besides, the subjective evaluation is purely to help tie to the objective data and make sense of what I am hearing to help you all get an understanding of how relevant the data is. The sound might not seem “full” to some users without a subwoofer. It is far more important that your evaluation music be something you are familiar with than it is to be esoteric for the sake of being esoteric. … and that’s it. While I tried to make these as accurate in SPL as I could, I cannot guarantee the relative levels are absolutely correct so I caution you to use this data as a guide but not representative of actual levels (measuring in the nearfield makes this hard as a couple millimeters’ difference between measurements can alter the SPL level). A good speaker will have little compression (< 1dB), where poorer speakers may suffer greater compression (> 2dB). The distortion threshold was exceeded above this SPL. The vocals are more in the foreground, but the sound isn’t flat or static. The MB42X feature silk dome tweeters and 4-inch carbon fiber woofers. As for bass… well, there’s really not much there. MB42comes only in … But, again, since this region is down so low relative to the treble region, it doesn’t really help. Mic placed about 0.50 inches - relative to the baffle - from each drive unit and port. I have provided both an absolute SPL version as well as a normalized version of both the horizontal and vertical sound fields. Power Handling: 75 W. Sensitivity: 85dB. Norah Jones “Tell Yer Mama”: Mechanical noise… Tinsel lead slap? This is a review of the older Micca MB42x, Click here to go to the updated review of the MB42x.If you just want to know more about the MB42x, this review is a pretty good read which is why I left it up, but it's not indicative of the sound of … I honestly didn’t believe them until I tested the MB42X by Micca myself. However, note: the 80Hz signal is a “brick wall” and does not emulate a typical 80Hz HPF slope of 24dB/octave. The dashed red line is for reference and shows the 1% distortion mark (but has no bearing on pass/fail). The distortion is high. I made it through about 7 songs before I just stopped. In my experience, all these factors play in to how the listener “connects” with the system. If you question the performance and can demo the speakers in your own home, I suggest you take advantage of the opportunity. If you have a high-Q resonance at 450Hz the 300Hz resolution data will not show this resonance because the frequency resolution only has a data point at 300Hz and 600Hz; skipping right over the 450Hz. System Components. So Polk Audio T15, while being a cheaper option, tends to get more favorable ⭐ reviews than the $90 Micca MB42X, as seen on the chart below. The blue shaded area represents the ±3dB response window from my calculated mean SPL value. Crossover Channel Qty. Tweeter: 0.75-Inch Silk Dome. If you want help understanding what this data means, watch the video below. Harmonic Distortion and Compression are provided at varying levels to get an idea of what happens as the voltage into the speaker is increased and overall output volume increases. Both speakers have 4.5″ woofers made of Kevlar. The above data can be summed up by looking at the tables above but is provided here again: Thiele-Small and Large Signal Analysis: copyright © 2019 gethugothemes all right reserved, Klippel’s In-Situ Room Compensation (ISC) module, Linear Lumped Parameter Measurement Module, Klippel’s Training 1 - Linear Lumped Parameter Measurement tutorial, Klippel’s Training 3 - Loudspeaker Nonlinearities tutorial, Songs from the Big Chair (2014 Deluxe Edition - Disc 1), Mark Keali’i Ho’omalu and Kamehameha Schools Children’s Chorus. I would strongly suggest using an EQ to help with the response. Micca has been a friend to budget audiophiles for a while now, releasing a series of affordable, compact and sometimes oddball speakers that do enough things right to catch audiophiles’ attention. Now that you understand my motives, let’s get started with the review. Both are currently free software. The response curve of the Micca MB42X MKIII is extremely non-linear; exhibiting as a wholly recessed midrange, a prominent bump between 1-2kHz and poor linearity above 4kHz. 2 speakers. But… it’s close enough. The impedance of a speaker varies depending on the frequency being played, and it is normal for most 8ohm rated speakers have impedance that dip as low as 4ohms or even lower. The result of painstaking fine tuning through balanced application of science and art, the crossover yields a transformed sound signature … My Micca MB42X-C is within the return window, I'm thinking of return the Micca and getting the matching Dayton MK442. frequency response graphs, CSD waterfall plots, subjective gear reviews. Components: Oppo BDP-103 playing music off my thumb drive feeding signal via HDMI to a Denon AVR-X4000 which then feeds in to a refurbished Adcom GFA-545 for power. Not simply because of subjective performance. Meaning, if a speaker is ideal and you tell your stereo to increase by 6dB by turning the volume knob +6dB, the output will increase by 6dB. With the frequency response range of 60Hz-20kHz, they offer a smooth and balanced performance. are all based on a 2.83 volts RMS logarithmic sweep at 1 meter to meet the standard sensitivity measurement spec. Note: This is not a standard merge of nearfield and farfield nor a merge of ground-plane and farfield. In the nearfield listening, the output was about the same level because of distortion limitations; I didn’t like them above 90dB. As you will see below, my music selection did a great job at providing enough range for me to identify the issues that readily appear in the data. Notice how well it matches the predicted in-room response. This speaker does not have that at all. passive. The MB42X is a very reasonably priced model, so you don’t have to drain your bank account in order to enjoy good sound quality. The Police “Wrapped Around Your Finger”: There’s nothing in the bassline below about 140Hz. The compression is high. The Micca MB42X is a pair of compact speakers featuring a 4-inch carbon fiber woofer and a 0.75-inch silk-dome tweeter. If there is a single set of data to use in your purchase decision, this is probably it. Midbass was lacking emphasis. The MB42X is a great choice for audiophiles who crave thunderous bass. https://youtu.be/iCjJufvW0IA. It definitely feels fine for the price and looks like it can last for many years. And, finally, here is a great video of Dr. Toole discussing the use of measurements to quantify in-room performance. The MB42X cabinets are somehow bulky for bookshelf speakers, with 6 in width, 7 inches in depth, and 10 inches in … Buy the Neumi BS5 if you’re looking for a budget set of bookshelf speakers. Typical merged responses still suffer low resolution in the midrange where the response is merged due to the necessity of windowing the impulse response to remove reflections. Before I dive in to the subjective feedback let me first give you the layout of my room…. On the specs side, you get an 85 dB sensitivity and 60Hz-20kHz frequency response. Thanks to the ISC module, the data I am providing here is higher resolution (~30Hz resolution) than an average person can provide without access to an anechoic chamber or the like. In a poll I found most listen to music in this range. I'm wondering if anyone has any experience with the Dayton MK442 as a center (I know people like to purchase as pairs and use them as L/R's). Klippel’s In-Situ Room Compensation (ISC) module is then used with the ground plane measurement to provide a ‘reference’ curve to the 4-pi measurement which then corrects for the room’s influence and allows me to generate a reflection-free far-field response from an indoors measurement. Note, again, the volume wasn’t that loud. Note: I don’t generally audition speakers with the typical “audiophile” music. Micca Mb42 has a filtering capacitor on its tweeters. The compression threshold was exceeded above this SPL. Using Klippel’s Distortion Analyzer 2, Linear Lumped Parameter Measurement Module, Pro Driver Stand and provided Panasonic ANR12821 Laser along with Klippel’s Training 1 - Linear Lumped Parameter Measurement tutorial, I measured this drive unit’s impedance and small-signal parameters. The null at the transistion around 4000Hz looks less severe than it is because I am only have data for one-third octave measurements. 75" silk dome - crossover: 12dB/Octave - enclosure: ported - frequency response: 60Hz-20kHz - impedance: 4-8 ohms - Sensitivity: 85dB 1W/1M - power handling: 75 watts (each) - dimensions: 9. I said it. And with a bookshelf speaker like this, it should absolutely be crossed above 100Hz to limit any playback near the Fs of 87Hz. It’s not bad, but not great either. And as a bonus, Micca MB42X speakerslook stylish too. Is it the room, the actual speaker itself, my brain, or a combination? Looking back at the data, this is the only area in the response that is linear within about 1/2-Octave above/below. I also love the matte finish and the magnetic grill. All of these parameters translate to a speaker that needs to large enclosure (so the Qtc will not be any larger; as the Qts itself is already relatively high), high low cutoff point (due to high Fs) and low sensitivity (even though the on-axis average SPL is ~ 85.5dB, the SPL in the bass region is in the low 80’s). This measurement follows the IEC 60268-21 Long Term SPL protocol, per Klippel’s template, as such: Each voltage test is 1 minute long (hence, the “Long Term” nomenclature). The MB42X bookshelf speaker from Micca inherits the looks of its predecessor, the MB42s model, with a simple ebony laminated wood grain design that allows it to blend into any room or décor. You would need a resolution of at least a half the width of the Q-factor; generally, 20Hz is adequate. With the frequency response range of 60Hz-20kHz, they offer a smooth and balanced performance. Too objective for subjectivists; too subjective for objectivsts. The Micca MB42x MKIII is a terrible speaker if you intend to listen to it as a budget audiophile speaker (or anything resembling that). The difference in the midrange to upper-midrange/low-treble is nearly 5dB and then a 3dB dip from low-treble to upper-treble above 7kHz. Such is the case in my evaluations. Micca lists these “Feature Highlights” on their site: That’s a big “no” to every-single-one of the above “features”. Audioholics has a great writeup on what these data mean (link here) and there is no sense in me trying to re-invent the wheel so I will reference you to them for further discussion. Multitone distortion testing. I purchased this speaker to compare against my recently reviewed Neumi BS5 (link here). Frequency Response of the Micca MB42Xand the Pioneer BS22 The similarities between the speaker responses might arise from the fact that there are significant similarities in their construction. From this you can determine how much absorption you need and where to place it to help remedy strong dips from the reflection(s). The low-level voltage version is standard because it ensures the speaker/driver is in linear operating range. 2-way. The bass was lacking because of the small woofer, and the treble had a … At this point I decided to move closer to see if listening in the nearfield would help (spoiler: it didn’t). All this result in a more open, dynamic, clean, and balanced sound, and numerous customer reviews prove it. The Pioneer BS22 and Micca MB42X both use dome tweeters. I listened to these speakers and made my subjective notes before I started measuring objectively. The speaker has a 4-inch woofer that is made from carbon fiber that helps to deliver rich bass sound. The distortion is high. Below are both the horizontal and vertical response over a limited window (90° horizontal, ±40° vertical). Since many will likely use this with a PC. Well, I’d be remiss for not delving in to that a little bit here. Plus, the rear port would be blocked killing the low end contribution it provides. Dimensions (inches): 9.5 x 5.8 x 6.5. Generally speaking, higher sensitivity speakers (like pro-audio speakers with 100dBSPL @ 2.83v/1m spec) suffer relatively no compression while lower sensitivity speakers (low 80’s dBSPL @ 2.83v/1m) suffer more compression. When used without a subwoofer, these speakers might sound not rich enough to some users. I purchased my sample from Amazon and it cost US $149 including Prime shipping. Below are the results.
