Bought it for a bedroom sub, but since it didn't match the description I am sending it back.

I have equipment to measure the frequency response. The low end reach is 35Hz at -3dB and 30Hz at -6dB. It is inaudible at 20Hz, so the spec if clearly wrong (even at unspecified attenuation).

PROS: + Well constructed.
+ Quality knobs & sockets.
+ Runs cool.
+ Auto standby.


CONS: - 30-35Hz low end, not 20Hz like in the spec table.
- Bass port makes wind noise and colors the sound. Overtones can clearly be heard from the port.
- Mine came with a bend corner from a drop, but the box was not damaged. It must have been dropped in the factory.

As Rdi from Santa Clara writes in his review, this sub is only good down to somewhere between 30 and 35 Hz. It is silent at 20 Hz. There is also noise (chuffing) from the port when playing at higher volumes. All that said, for the money, it's a pretty good, if not great value. Would make a very good addition to smaller speakers that only play down to 50 or 60 Hz or in a home theater. I would recommend them for use in all but higher volume, critical listening situations.

PROS: Price!

CONS: Doesn't even begin to reproduce sound at the stated specs. Chuffing oise from ports.

I'm only a few hours into owning this so take that for what it's worth, however I'm very, very pleased, I think I would be happy with this for 3X the price. I unboxed it hooked it up to my Rokit RP-8 G2s, and was instantly over the moon. Gone was the honky, dulling, mud that the Rokits tend to have, and suddenly present was the power of sub-bass, and there is more than my room or ears need. Should I need to level the house with Bass, I'm pretty sure I have the ability, but I can actually hear the full rich sound with far less overall volume, I can turn everything down, and be happy with what I'm hearing. FINALLY!



No joke, I had an Rokit RP-10s sub, that supposedly delivered equally in the power ratings, at a price 2X this. Going from memory, and recent visits to a freinds studio which also has one of the Rokits, I think Monoprice wins. That's even if you take the price differential and toss it out the window, even money, I'm not sure I'd trade this for it, if I had to go with what I was hearing. For half the money, No-Brainer in my opinion. We'll see how well that stands over time, but if this lasts 6 months, It's still a great deal.

PROS: Solid. Connections Galore. Balanced XLR in and Out, crossover works nicely, option to A/B via foot switch. Auto Power on/off/standby, great rubber feet. Built well, includes removable grille.

CONS: Not a major brand name, uncharted territory with reliability, and long term quality.

After a little LinkedIn research from what a friend told me, Jess McIntyre was in charge of designing the Pro Audio line for Monoprice after M-Audio was dismantled from the InMusic buyout.

My first sub came defective, but the RMA team replaced it free of charge or shipping, which is great because I live in Mexico.

Second unit arrived and worked like it was supposed to. In my secondary studio it sounded good, but there's not much treatment there. Main studio is well-built and it sounds perfect with the JBL LSR305's.

I am considering a second sub, and this one fits the bill. Will definitely buy this again.

The other reviews seem to be very accurate. There is port noise at high volumes and the freq response seems to be in the mid 30s not 20Hz.

Other than that though this sub is an amazing value. Sounds infinitely better than the Klipsch.

I do have a small home recording studio that I can put this in. However, my old JBL 12" sub went that I've had for about 20+ years went on me that I was using for my home theatre, so I was looking to replace that. So I figured, well, I should be able to use this somewhere! Let me tell you, I hooked it up to my home theatre, since the trs input will also accept an unbalanced input that a normal receiver puts out, and I'll be darned, it sounds pretty good! Now let me be fair and honest, don't expect it to sound like a $400 sub. It's not a $400 sub! It does not sound as good as the one it's replacing, BUT, for a third of the cost you are not going to beat this. So I gave it 10 stars since it's easily worth double the price, EASILY! I may just buy another one for the studio too! Heck, I may even buy a third for my upstairs home theatre set-up! I mean, I can buy 3 for less than 1 top of the line woofer and it will sound 90% as good. Unless you are an audiophile, you will not notice the difference, I'm tellin ya!

PROS: Great Price, lot's of connections

CONS: None for this price

I was a bit skeptical about this subwoofer, even after reading the reviews. But, while I thought and thought about it, they dropped the price so I pulled the trigger and ordered one. Two business days later, the UPS guy showed up with it. I had him bring it around back to my studio, he brought it in, laid it gently on the floor and then disappeared.



Unboxing was rather undramatic, mostly because there wasn't so much as a scratch on the shipping container. The sub came DOUBLE-BOXED, which is a GREAT way to protect anything during shipping, and the subwoofer was in perfect shape. I also ordered a pair of XLR cables to connect my JBL studio monitors to the sub. I already had/have XLR cables that I used to connect my Focusrite DI (Digital Interface) to JBL monitors, so I just unplugged them from the speakers and plugged them into the inputs on the sub.



Using the newly acquired XLR cables from Monoprice (VERY good quality cables, by the way), I connected the JBL monitors to the sub outputs, set the cutoff frequency to 120 Hz, the volume knob to 0db, powered up my JBL monitors, plugged in the power cord on the sub and turned the On/Off switch to the On position.



The On/Auto/Off switch was already in the 'Auto' position, and since the Focusrite DI was turned off, there was no signal going to the sub, so it stayed Off. I powered up my computer and the DI, launched Foobar2000, loaded a few 24-bit audio tracks into it and hit the Play button. HOLY CRAP this sub is LOUD! I turned down the volume control to about -6db, listened to the audio track, tweaked the volume on the sub a tiny bit more and settled back into my office chair to evaluate the sound quality.



I have to say that I was immediately impressed with this sub, even though a brand new, right out of the box sub isn't EVEN broken in yet. I suspect it'll take 100 hours or so before the sub really starts to shine, but that's okay. I went through the same thing with my JBL studio monitors, my AKG K712 cans, my tube headphone amp, the two tube preamps I use as buffers for guitar inputs to my Focusrite DI ... well ... everything has to break-in/burn-in before things starts to REALLY sing.



Getting back to the sub's sound quality, for the money, this thing is THE bargain of the century. Bass response is very clean, tight and punchy. It's NOT boomy or in your face and it reminded me very much of the same level of bass quality my AKG K712 headphone exhibit, which is perfect (at least to my ears).



While audio quality is a very individual and subjective topic, my last high-end home theatre system set me back in excess of $20K and was comprised of nothing but high-end gear. So, I'm used to high quality components and shelling out LOTS of dough to get the sound quality I want.



That said, my home studio is just a hobby, I had a hard time justifying spending megabucks on most of the hardware I selected, and virtually everything I purchased was either on sale or highly discounted. The Monoprice studio subwoofer was/is my last and final purchase, in terms of speakers, and I couldn't be happier. Not only did I get it on sale, but it FAR exceeded my expectations in EVERY area. I was telling my son about it and now HE wants one. He sets up/installs studios for a living, so he know his gear and he swears by ALL things Monoprice.



The bottom line is this subwoofer is an incredible buy and the sound quality is as good as anything I've ever heard (studio and/or home entertainment gear). I can HIGHLY recommend this subwoofer without hesitation. Sound-wise, it matches up perfectly with my JBL studio monitors, which was one of the BIG things I was concerned about. I WAS going to purchase the matching JBL subwoofer ... at OVER twice the price of the Monoprice studio sub ... only because I thought it would match better (sound-wise) with my JBL studio monitors. Obviously, that's NOT going to happen and I am THRILLED that the Monoprice sub works so amazingly well with my JBLs.



If you're in need of a studio sub, wait for this one to go on sale and then JUMP on it! I'm sure you'll be just as blown away as I am and continue to be with this sub. The more I listen to it, the more I love it. While I can't vouch for any other studio monitors, sound-wise it matches perfectly with my JBL monitors, which is the ONLY thing I really cared about.



THANKS, Monoprice. You guys ROCK!

PROS: Price, workmanship, features, sound quality, fast shipping (it shipped the day I ordered it), good packaging, EVERYTHING!

CONS: Nothing, nada, zip.

You get far more than you pay with this subwoofer. I've tried and returned several subwoofers that were more than 4 times the price and nowhere near as good. Monoprice you are going to become disruptive to the pro audio market.

PROS: well built, subtle design, nice quality finish

CONS: not one thing...

I can only speak from experience. some have wrote that they experience the pop sound when turning on or turning off. Even when I use the auto button, it'll pop auto on. Anyways I use it at volume -30db so i don't expect the drivers to be damaged in anyway, however i only had it for 5 days so i don't know BUT... i'm extremely satisfied with this product. I use it with my JBL 305 input sensitivity -10 and 4th notch at the volume. (Don't know if that's the most accurate caliberation so if anyone knows please let me know.) The sub itself is just way too powerful so i can't even turn the volume up a bit without bothering my neighbor.

buying this sub would be a wise decision if you're an audiophile as well as an producer/engineer ( like i am) whether u do it professionally or not. I mean this is just a sub and how clear can a bass get below 80hz anyways? you wanna spend $500 on a quality sub..?. not a good choice i'll tell ya. you think you're ok with just a 5 inch or 8 inch without a sub... that's also not a wise decision to make. you'd be biased to think that just cuz u don't have one yet.

trust me on this, like i said i only had this for 5 days so i don't know how long it may last me but so far i know for sure it's been a perfect match to my JBL 305's. hopefully it'll last longer than the warranty period.

PROS: powerful and everything else. reasonable price. Auto on/off is convenient, also footswitch is good.

CONS: Almost nothing except for the tiny popping sound. And a little bit of distortion if you haven't broken it in but yea like i said i only had it for 5 days and it's disappearing slowly. Plus, you won't hear that distortion since you're not going to be right next to the bass port of it which is facing away from you.

heavy lol call me a weak sauce all you want but it's a hassle to even reposition it 2 inches away from the original spot under the table.

Still playing with room placement, crossover point and gain, but am well pleased so far. Shipped in double box with corner pads which was a big plus for me as UPS tried their hardest to beat the outside box to bits. Looked awful until unboxed - not a scratch on it. Someone who designed the shipping boxing should be given a raise! Nice subwoofer for this price point one can say it's a great value. I have an 8" in another application which cost 5 times the price. I'd say it is not as powerful but does have somewhat better definition. This 10 is a nice unit - I would easily buy it again.

PROS: Plenty of depth and power. Trouble-free installation. Plays well with 8" Monoprice studio monitors.

CONS: Muddy when first installed, before full break-in. Hang in there - it gets more and more defined as the speaker goes through the first 50 hours or so.
