The MSUB-A122 leaves me with two questions. First, is it the world’s best crazy-cheap speaker, or does that honor fall to the Dayton Audio B652? I can’t decide, so let’s just call it one of the best speaker bargains in the world. Second, what would a stack of four of these things on each side of my room sound like?
Frequency response
47 to 130 Hz ±3 dB
Bass output (CEA-2010 standard)
• Ultra-low bass (20-31.5 Hz) average: NA
20 Hz NA
25 Hz NA
31.5 Hz 98.3 dB
• Low bass (40-63 Hz) average: 115.3 dB
40 Hz 112.3 dB
50 Hz 117.9 dB
63 Hz 115.6 dB
I made the frequency response measurement seen in the chart with the crossover set to 150 Hz, using ground plane technique with a Clio FW analyzer in stepped sine mode. The sub sat on the ground and the microphone was placed 2 meters from the front of the sub. The measurement is smoothed to 1/6th of an octave. Obviously, this isn’t a deep-bass subwoofer. Whoever engineered it seems to have taken the meager resources at his disposal and wisely focused 100% of his efforts on the range from 40 to 100 Hz. Combined low-pass function of the crossover, driver and enclosure is about -16 dB/octave.
To measure bass output, I used the CEA-2010 method. The MSUB-A122 has plenty of output in the low bass octave (40-63 Hz), comparable to what I’ve measured from average 10- and 12-inch subs. There’s still decent output at 31.5 Hz, but below that, bupkis.
Incidentally, when I hooked up the Dayton Audio B652s I checked the subwoofer’s speaker-level and line-level outputs with a digital multimeter to see if they include any high-pass filtering to take the bass out of the satellite speakers. They don’t.
Did you get a chance to listen to it?
Yes! See page 2 under "Performance"
Not sure if I got a bad one or what but mine sounds ok except for every few minutes when it bumps like it got a big bass signal. It is quite annoying. I had to disconnect it. I would return it but I threw away the box and it would cost a lot to return so it will just sit here. Maybe if I get a new receiver it will be better. Some day...
Hi Registered,
Sorry the subwoofer didn't meet your expectations. We'd love to get some more feedback from you so that we can work on improvements to our products or possibly determine if you might have gotten a defective product. Also, you don't necessarily have to return it in the original box as long as you return all the included materials. Please contact us through our live online chat feature on our website so we can further discuss the issues you are having and also see what we can do to make the return process easier for you.

You get what you pay for! I shudder to think of all the people who will WASTE $84 on this abomination of a product! It shouldnt even really be called a "sub" or "subwoofer", because there is nothing "sub" about it's frequency range! If you are looking for enhanced MID-bass, by all means, waste your money! If you are looking for a woofer that will MAKE YOUR MAIN SPEAKERS SOUND WORSE, give this a try! Otherwise, save your money and get a REAL subwoofer. There are PLENTY of good choices under $1000. Find one that fits your budget AND your expectations of sound quality...and if quality matters AT ALL....stay away from monoprice entirely!
John Nemesh. Keep pushing your overpriced products with your company at AVAD and stop being so butt-hurt you can't keep ripping people off forever. I am sorry you aren't going to milk a few grand from a poor sucker.
1. Where does the $9 shipping come in? Mine showed up at ~$32.
2. I'm surpised at jnemesh! He missed using an exclamation point on two sentences! He is obviously an inferior poster!
