But… it’s close enough. Is it the room, the actual speaker itself, my brain, or a combination? Below are the nonlinear results. The minimum impedance dips to about 4.2 Ohms around 1.4kHz with a nominal impedance at about 5 Ohms. 5" (D) Max SPL for 20Hz to 20kHz is approximately 88dB @ 1 meter. Micca’s MB42X set is small and compact, but this pair sounded poor next to all of the other contenders. They can offer you a more than decent performance and a nice, elegant appearance. Meaning that placing the speaker against a wall would be pointless. Ground plane measurements are perfect for this but are subject to aiming/ground absorption (grass) and related issues above 400Hz. These Micca speakers are a perfect and cheap bookshelf speakers under $100 for the home. This is a review and detailed measurements of the Micca RB42 bookshelf/desktop computer speaker. 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. The rounded corners make a better impression than SX6sharp ones. This speaker is quite a bit smaller than the Neumi, which I discuss in my video above, but I was optimistic about its performance based on many other past reviewers’ positive impressions. But because of other factors such as aesthetics, pride of ownership, etc. Well, I’d be remiss for not delving in to that a little bit here. Note the legend provided in the top left of each image which helps you understand speaker orientation provided in my global plots below. 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. You may ask just how useful the above prediction is. Amplification Type. Distortion is very high below 200Hz with greater than 5% THD at typical listening levels. Even though the response is not flat, the MB42X has a frequency response range of 60Hz to 20KHz. The MB42X … The tweeter is level biased just slightly below neutral to reduce listening fatigue without losing a ounce of detail. 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. And you will have a way to compare various speakers’ SPL limitations with each other. I couldn’t take listening to the speakers anymore. Micca MB42X-C Specifications: Woofer: Dual 4″ Carbon Fiber Cone with Rubber Surround; Tweeter: 0.75″ Silk Dome; Crossover: Full 18dB/Octave* Enclosure: Ported; Frequency Response: 60Hz-20kHz; Impedance: 4-8 Ohms; Sensitivity: 86dB 1W/1M; Power Handling: 100 Watts (Each) Dimensions: 5.3″ (H) x 15″ (W) x 7.1″ (D) If you can help by chipping in, I would truly appreciate it. Notice how well it matches the predicted in-room response. This model can really compete with options that are more expensive and will be up to par with almost any $100-150 speaker. 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. I would strongly suggest using an EQ to help with the response. Both speakers have 4.5″ woofers made of Kevlar. I measured the response of the speaker’s vertical and horizontal axis in 10-degree steps over 360-degrees. 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 cabinets are somehow bulky for bookshelf speakers, with 6 in width, 7 inches in depth, and 10 inches in … Some prefer not to normalize the data. 5" (H) x 5. Micca Mb42 has a filtering capacitor on its tweeters. Both are currently free software. 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. 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. You also want to listen to music you enjoy because auditioning a stereo system shouldn’t feel like a chore. System Components. Since many will likely use this with a PC. One of the things I absolutely need to mention in my review is the build quality of Micca speakers. 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. The reason for the two measurements is because it is unfair to expect a small bookshelf speaker to extend low in frequency. Not simply because of subjective performance. Here’s my Amazon affiliate link if you want to purchase it and help me earn about 2% of the price. Above this, the distortion is anywhere from 2-3% THD in the midrange at these same listening levels. 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 The green line shows the final measurement where either distortion and/or compression failed. The Micca MB42x MKIII is a terrible speaker if you intend to listen to it as a budget audiophile speaker (or anything resembling that). 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. Tweeter: 0.75-Inch Silk Dome. Micca MB42X. It truly reaches those low-frequency depths and produces them well. Frequency Response. Though, I suggest you buy the Neumi BS5 if you are in the market for a sub-$100 bookshelf speaker. On top of that, it's fairly safe to say that Polk Audio T15 are more popular speakers, based on their 4,000+ reviews. 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. Nominal Impedance. Here’s the rundown of my subjective notes and where it fits with objective: Overall?…. 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). For the size of the speakers, the bass works really well. It’s rare I have a mid/woofer be limited in excursion due to inductance. The Micca MB42X has less variability on the high end than the Dayton B652, which will ultimately sound better for vocals and most instruments. I demoed these speakers without a crossover and without EQ. The blue shaded area represents the ±3dB response window from my calculated mean SPL value. I have provided both an absolute SPL version as well as a normalized version of both the horizontal and vertical sound fields. The Micca MB42X is a pair of compact speakers featuring a 4-inch carbon fiber woofer and a 0.75-inch silk-dome tweeter. 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 … 2-way. Power Handling: 75 W. Sensitivity: 85dB. The only way to achieve this is in a large parking lot or open field. The B652 is louder, but no flatter, on the low end. These data are captured using Klippel’s TRF module and a mixture of ground-plane measurement and 4-pi free-field measurement. SX6comes in two colors black and natural walnut. 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. 60 - 20000 Hz. Note: This is not a standard merge of nearfield and farfield nor a merge of ground-plane and farfield. The sound might not seem “full” to some users without a subwoofer. 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. As you can see in the blue window above, the Micca MB42X Mark III is all over the place. Such is the case in my evaluations. But on the other hand, Mb42x has an enhanced crossover section. I purchased this speaker to compare against my recently reviewed Neumi BS5 (link here). Frequency Response: 60Hz-20kHz. Each of the units features a four-Inch woven carbon fiber woofer with rubber surround along with a silk dome tweeter. frequency response graphs, CSD waterfall plots, subjective gear reviews. Max SPL for 80Hz to 20kHz is approximately 100dB @ 1 meter. My Micca MB42X-C is within the return window, I'm thinking of return the Micca and getting the matching Dayton MK442. The veneer finish of SX6made an average impression on me. 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 . It suffers extreme non-linearity and high distortion. Woofer: 4-Inch Carbon Fiber. Now that you understand my motives, let’s get started with the review. Just “there”. The above spectrograms are the standard way of providing directivity graphics by most reviewers. Micca’s MB42X are an upgrade upon the older MB42s with an actual crossover (hence the appending “X”) that properly dedicates the correct frequencies to the tweeter and woofer respectively. They were that bad. With that in mind, what you see below is first the Total Harmonic Distortion at varying output levels. Too objective for subjectivists; too subjective for objectivsts. Micca’s build quality feels sturdy with light 3/8′ vinyl covered particleboard. Distortion is minimal. 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. Too objective for subjectivists; too subjective for objectivsts. The compression is high. 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. But, again, it’s a small bookshelf speaker with a 4-inch mid. 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. The overall performance didn’t actually suit the price category of these speakers. A good shop or manufacturer understands this and allows buyers to try items out at home before purchasing or they offer a reasonable return policy. :). At least not to me. The treble is also about 5dB higher than the midrange. But, again, since this region is down so low relative to the treble region, it doesn’t really help. I listened to these speakers and made my subjective notes before I started measuring objectively. There’s truly nothing positive I can say about this speaker. While I think anyone in their right mind would know not to expect tons of output (not just bass; but overall volume) from a speaker this size, what you would expect is a semblance of linear frequency response. The low-level voltage version is standard because it ensures the speaker/driver is in linear operating range. Please see my Analysis section below for discussion on this. This is a minor drawback, but I know that it might annoy some users since it is sometimes inconvenient to reach to the back of the speaker every time you need to adjust the volume. With the frequency response range of 60Hz-20kHz, they offer a smooth and balanced performance. A spectrogram is an alternate way to view this full set of data. It definitely feels fine for the price and looks like it can last for many years. The MB42X impresses with its powerful picture projection, it’s easy to mistake the speakers for a … When used without a subwoofer, these speakers might sound not rich enough to some users. Enclosure: Rear ported, matte black vinyl. As you can imagine, providing all those data points in a single FR-type graphic below is a bit overwhelming and confusing for the viewer. The tuning frequency of the enclosure is approximately 50Hz. 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). I try to do a few listening sessions over a couple days so I can give my ears a break and come back “fresh”. 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. Multitone compression testing. 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. Crossover: Advanced 9-element. The old design of the Mb42 did not have a cross over frequency but the new model has a crossover frequency. The midrange exhibits a trough centered on ~300Hz. Steve Winwood’s “Higher Love”: Wide left soundstage; missing something below 1kHz tonally; hollow sounding. frequency response graphs, CSD waterfall plots, subjective gear reviews. Each set consists of 2 graphics: Normalized plots make it easier to compare how the speaker’s off-axis response behaves relative to the on-axis response curve. 2 speakers. What really impressed me about these speakers was the crispiness of the sound (even at highs) and a deep bass. I listened first at my typical listening position about 11 feet away. … and that’s it. Dimensions (inches): 9.5 x 5.8 x 6.5. 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. Note, again, the volume wasn’t that loud. Nearly 70 measurements in total are represented in my data. That’s an easy, easy decision. Requires Amplifier: Yes. The Pioneer BS22 and Micca MB42X both use dome tweeters. And here is the nearfield setup (with the lawn chair in all its glory). Mic placed about 0.50 inches - relative to the baffle - from each drive unit and port. The voltage just before this is used to help determine the maximum SPL. Thus, this is sometimes referred to as “Spinorama” data. This is also an ideal option for someone who’s not ready to invest too much in a pair of speakers. Micca MB42X The Micca MB42X are small, elegant, and impressive bookshelf speakers that belong to a more affordable category of audio speakers. You can hide them with the help of a magnetic grill, which allows for a more customizable use, as you will be able to change the appearance of your Micca MB42X every day. 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 evolution of the original irreverent and irrelevant and non-authoritative site for headphone measurements, i.e. Multitone distortion testing. There is nearly 5dB difference between the midrange and the treble. 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. So, if you’re one of those people, think about investing in a subwoofer. Distortion and Compression measurements were completed in the nearfield (approximately 0.3 meters). 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. It’s not bad, but not great either. The Police “Wrapped Around Your Finger”: There’s nothing in the bassline below about 140Hz. Some prefer to normalize the data. You can watch a demonstration of this testing via my YouTube channel: Crossover Channel Qty. I varied it between 85-90dB, occasionally going up to the mid 90’s to see what the output capability was. 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 have provided two sets of data: one set for horizontal and one for vertical. 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. All this result in a more open, dynamic, clean, and balanced sound, and numerous customer reviews prove it. In my experience, all these factors play in to how the listener “connects” with the system. The mean SPL, approximately 85.5dB at 2.83v/1m, is calculated over the frequency range of 300Hz to 3,000Hz. The vocals are more in the foreground, but the sound isn’t flat or static. Because of the enhanced crossover, the … It’s not even worthy enough to hold a baseball. However, these “collapsed” representations of the sound field are not very intuitively viewed. If you question the performance and can demo the speakers in your own home, I suggest you take advantage of the opportunity. Impedance measurements are provided both at 0.10 volts RMS and 2.83 volts RMS. The Micca MB42X are small, elegant, and impressive bookshelf speakers that belong to a more affordable category of audio speakers. The compression is high. I purchased my sample from Amazon and it cost US $149 including Prime shipping. The voltage just before this is used to help determine the maximum SPL. Using Klippel’s Distortion Analyzer 2, Large Signal Identification Module, Pro Driver Stand and provided Panasonic ANR12821 Laser along with Klippel’s Training 3 - Loudspeaker Nonlinearities tutorial, I measured the linear, nonlinear and thermal parameters of this drive unit. I have thousands of high-quality albums ranging from pop to metal to jazz and all around. And, finally, here is a great video of Dr. Toole discussing the use of measurements to quantify in-room performance. Let’s look at the measured in-room response I captured using my UMIK-1 and REW. 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. For frequencies lower than 60Hz, you may not hear them, but will notice the intense vibration coming from the woofer. As proof, Pioneer introduces the SP-BS22-LR bookshelf speakers. With the frequency response range of 60Hz-20kHz, they offer a smooth and balanced performance. Unless you absolutely need a speaker this size, you have the ability EQ until your heart (or ears) is content and you don’t plan on listening louder than talking levels in the nearfield… don’t buy this speaker. You would need a resolution of at least a half the width of the Q-factor; generally, 20Hz is adequate. Micca MB42 Bookshelf Speakers – An Affordable, Quality Set of Entry-Level Speakers for Those Who Are On a Budget. 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. Not “involving”. Sausalito Audio also has a good write-up on these curves here. And as a bonus, Micca MB42X speakerslook stylish too. Midbass was lacking emphasis. This takes a 360-degree set of data and “collapses” it down to a rectangular representation of the various angles’ SPL. 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. You can read as many reviews as you want, but let me tell you this: You won’t find anything better in this price category. Well, looking at the data we see a big trough smack in the midrange at about 300Hz. The higher voltage is to see what happens when the output voltage is increased to the 2.83vRMS speaker sensitivity test. 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. So, I came up with a different way to view the speaker’s horizontal and vertical sound field by providing it across a 360° range in a globe plot below. Either way, it’s a useful visual to get an idea of the directivity characteristics of a speaker or driver. 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. The result of painstaking fine tuning through balanced application of science and art, the crossover yields a transformed sound signature … Furthermore, you can find discussion in Dr. Floyd Toole’s book “Sound Reproduction”. The red line shows the final measurement where either distortion and/or compression failed. 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. When I later tested the speaker and looked at the objective data, I realized why I hated their sound. 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. https://youtu.be/iCjJufvW0IA. In the real-world, however, a speaker is a mechanical device and there are compression effects that can limit the output volume and, therefore, you could possibly only get an actual increase in volume of 5dB. Overall, I found the max SPL I could drive the speakers to was around 88-90dB at my listening position, depending on the music. The above data can be summed up by looking at the tables above but is provided here again: Thiele-Small and Large Signal Analysis: When a crossover is used the compression near the speaker’s Fs is attenuated and overall the compression effects are mitigated. They sound more expensive. The Neumi is the same price as these Micca speakers and the Neumi performance is leagues better than the Micca. Fluance SX6 speakers are much taller than Micca MB42X. The speaker has a 4-inch woofer that is made from carbon fiber that helps to deliver rich bass sound. However, I will explain these curves lightly and provide my own spin on what they mean (pun totally intended). The engineers at Micca have found a way to offer great quality in terms of how the speakers sound and durability, all at an affordable price. This, obviously, won’t allow you to adjust the quality of the sound and maybe make it more “full.” Which leads us to the next drawback. High quality home audio doesn't have to break the bank. Micca MB42x Bookshelf Speakers. 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). There is a high-Q peak centered around 115Hz but that doesn’t do much except add some unnatural ‘umph’ to kickdrums via the harmonic. I said it. I chose not to run Dirac Live with these speakers because I wouldn’t recommend anyone buy these and I didn’t want to waste my time with these speakers anymore. If there is a single set of data to use in your purchase decision, this is probably it. Looking back at the data, this is the only area in the response that is linear within about 1/2-Octave above/below. 8" (w) x 6. MB42comes only in … Again, as a pointer to the wide horizontal envelope, notice how the Rear Wall Bounces Curve is relatively high in amplitude (for a front-facing tweeter, at least) until about 10kHz. This can easily be done with APO Equalizer and Room EQ Wizard (REW). Depeche Mode’s “Enjoy The Silence”: sounds distant; hollow through the entire midrange. From this you can determine how much absorption you need and where to place it to help remedy strong dips from the reflection(s). Below is a breakout of the typical room’s Early Reflections contributors (floor bounce, ceiling, rear wall, front wall and side wall reflections). The ISC module permits results with as-close-to-anechoic as one can achieve without being anechoic. I have to warn you: this model doesn’t feature bass or treble controls. 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). This can easily be done with APO Equalizer and Room EQ Wizard (REW). And in a speaker like this; one that is most likely to be used from 80Hz all the way out to 20kHz, that is a problem. The MB42X speakers are a perfect option for the indoor use. Micca RB42 Review - These are the brand new Micca RB42 mini bookshelf speakers. Updated driver level matching to result in overall smoother response; Posted in: Micca MB42X, Micca MB42X-C. 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. This means, more demanding audiophiles may consider the sound to be somewhat dull and lacking depth. Norah Jones “Tell Yer Mama”: Mechanical noise… Tinsel lead slap? There’s truly nothing positive I can say about this speaker. It's … As for bass… well, there’s really not much there. Here’s a link to the Neumi BS5: Now, let’s get to the data so you can see why I heard what I heard. For all the reasons listed above: What I provide here is objective-heavy analysis. At this point I decided to move closer to see if listening in the nearfield would help (spoiler: it didn’t). Each bookshelf speaker features an advanced 18dB/Octave crossover design. You can also join my Facebook and YouTube pages if you’d like to follow along with updates. The MB42X feature silk dome tweeters and 4-inch carbon fiber woofers. Micca MB42X specifications: - woofer: 4" carbon fiber, rubber surround - tweeter: 0. Below are the results. Bruno Mars’ “24K Magic”: Biting highs somewhere above 4kHz. Comparatively, this Micca speaker isn’t even in the same ballpark. I currently own the Micca MB42X and the now discontinued Micca Club 3. The dashed blue line represents the -20dB (10% distortion) threshold for failure. The linear excursion is capped at 1.4mm one-way due to inductance variation. And with a bookshelf speaker like this, it should absolutely be crossed above 100Hz to limit any playback near the Fs of 87Hz. Finally, the volume controls and the power switch are placed in the back of the main speaker. 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. 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. The result is a much improved budget-tier bookshelf speaker that is performant across the entire range. 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). 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. In the nearfield listening, the output was about the same level because of distortion limitations; I didn’t like them above 90dB. The following set of data is populated via 360-degree, 10° stepped, “spins” from vertical and horizontal planes resulting in 70 unique measurements. I did not want my knowledge of the measurements to influence my subjective opinion. The null at the transistion around 4000Hz looks less severe than it is because I am only have data for one-third octave measurements. If you want help understanding what this data means, watch the video below. I would strongly suggest using an EQ to help with the response. A good speaker will have little compression (< 1dB), where poorer speakers may suffer greater compression (> 2dB). YUCK. This speaker does not have that at all. This speaker also seems to be the favorite of youtube bloggers, helped partly by generous seeding of … I have provided a “normalized” set of data as well. The Micca MB42X maximum power is 75 watts per speaker. The reason these speakers are one of the best budget bookshelf speakers is mainly down to the crossover, a feature that was not included in the previous model. That means a data point every 300Hz. Before I dive in to the subjective feedback let me first give you the layout of my room…. The Micca MB42x MKIII is a terrible speaker if you intend to listen to it as a budget audiophile speaker (or anything resembling that). 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.
