micca mb42x frequency response

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 . Distortion is minimal. 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. Though, I suggest you buy the Neumi BS5 if you are in the market for a sub-$100 bookshelf speaker. Before I dive in to the subjective feedback let me first give you the layout of my room…. It’s not bad, but not great either. The red line shows the final measurement where either distortion and/or compression failed. Requires Amplifier: Yes. Multitone distortion testing. This speaker does not have that at all. 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. The voltage just before this is used to help determine the maximum SPL. 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. 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. 2 speakers. For all the reasons listed above: What I provide here is objective-heavy analysis. 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. You would need a resolution of at least a half the width of the Q-factor; generally, 20Hz is adequate. The above data can be summed up by looking at the tables above but is provided here again: Thiele-Small and Large Signal Analysis: 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). 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 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. At least not to me. The old design of the Mb42 did not have a cross over frequency but the new model has a crossover frequency. In a poll I found most listen to music in this range. As for bass… well, there’s really not much there. frequency response graphs, CSD waterfall plots, subjective gear reviews. I purchased this speaker to compare against my recently reviewed Neumi BS5 (link here). 5" (D) Whether you use them as stereo speakers or part of a multi-channel home theater system, their ability to handle 90 watts the SP-BS22-LR's deliver wide frequency response and sophisticated sound quality regardless of the source. And below is the Predicted In-Room response compared to a general Target curve equaling -1dB/octave. Power Handling: 75 W. Sensitivity: 85dB. 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). The ISC module permits results with as-close-to-anechoic as one can achieve without being anechoic. Norah Jones “Tell Yer Mama”: Mechanical noise… Tinsel lead slap? Such is the case in my evaluations. 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. The dashed red line is for reference and shows the 1% distortion mark (but has no bearing on pass/fail). Too objective for subjectivists; too subjective for objectivsts. It definitely feels fine for the price and looks like it can last for many years. This means, more demanding audiophiles may consider the sound to be somewhat dull and lacking depth. 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. Now that you understand my motives, let’s get started with the review. For example, most free-field measurements are only reflection-free until approximately 3 milliseconds, or about 300Hz. Some prefer not to normalize the data. Nearly 70 measurements in total are represented in my data. Micca RB42 Review - These are the brand new Micca RB42 mini bookshelf speakers. The result is a much improved budget-tier bookshelf speaker that is performant across the entire range. 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 … Max SPL for 20Hz to 20kHz is approximately 88dB @ 1 meter. 60 - 20000 Hz. 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. At this point I decided to move closer to see if listening in the nearfield would help (spoiler: it didn’t). When used without a subwoofer, these speakers might sound not rich enough to some users. I don’t typically listen to “audiophile” music because I just don’t enjoy it. Fluance SX6 speakers are much taller than Micca MB42X. The Micca MB42 is one of the most purchased bookshelf speakers up to date. 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. In the nearfield listening, the output was about the same level because of distortion limitations; I didn’t like them above 90dB. 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. 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. Note: I don’t generally audition speakers with the typical “audiophile” music. 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 frequency response rolls off over 16k significantly, while there are some spikes and dips in the lower ranges from 128 Hz to 800 Hz. 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. On one hand, Mb42 doesn’t have a crossover. Additionally, the MB42X utilizes a highly optimized 9-element crossover with full 18dB/octave* alignment and compensation network. This takes a 360-degree set of data and “collapses” it down to a rectangular representation of the various angles’ SPL. The speaker has a 4-inch woofer that is made from carbon fiber that helps to deliver rich bass sound. 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. 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) 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. You may ask just how useful the above prediction is. Featuring the range of 60Hz-20kHz, such frequency response allows for a rather balanced sound. 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. Because of the enhanced crossover, the … I couldn’t take listening to the speakers anymore. As I said above, the provided frequency response graphs were given with a limited set of data. These data are captured using Klippel’s TRF module and a mixture of ground-plane measurement and 4-pi free-field measurement. 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. Frequency Response: 60Hz-20kHz. 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. 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. On top of that, it's fairly safe to say that Polk Audio T15 are more popular speakers, based on their 4,000+ reviews. One major downside to “gating” or “windowing” the impulse response is this low-resolution does not show resonance in the midrange. The Micca MB42X has less variability on the high end than the Dayton B652, which will ultimately sound better for vocals and most instruments. MB42comes only in … However, some is given using Klippel’s graphing. 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. Below are the nonlinear results. 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 measured the response of the speaker’s vertical and horizontal axis in 10-degree steps over 360-degrees. 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). In my experience, all these factors play in to how the listener “connects” with the system. Some prefer to normalize the data. The overall performance didn’t actually suit the price category of these speakers. It's … It’s not even worthy enough to hold a baseball. Depeche Mode’s “Enjoy The Silence”: sounds distant; hollow through the entire midrange. I demoed these speakers without a crossover and without EQ. 5" (H) x 5. They can offer you a more than decent performance and a nice, elegant appearance. 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. 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. The rounded corners make a better impression than SX6sharp ones. They sound more expensive. Either way, it’s a useful visual to get an idea of the directivity characteristics of a speaker or driver. For frequencies lower than 60Hz, you may not hear them, but will notice the intense vibration coming from the woofer. Updated driver level matching to result in overall smoother response; Posted in: Micca MB42X, Micca MB42X-C. The evolution of the original irreverent and irrelevant and non-authoritative site for headphone measurements, i.e. The Micca MB42x MKIII is a terrible speaker if you intend to listen to it as a budget audiophile speaker (or anything resembling that). There’s truly nothing positive I can say about this speaker. However, 20Hz resolution is roughly 50ms of window-free response. I have thousands of high-quality albums ranging from pop to metal to jazz and all around. The distortion is high. If you want help understanding what this data means, watch the video below. Below are the results. If there is a single set of data to use in your purchase decision, this is probably it. And you will have a way to compare various speakers’ SPL limitations with each other. 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. 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. The vocals are more in the foreground, but the sound isn’t flat or static. 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.
