Never Miss a Deal.

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.

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.

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.

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

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...

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.

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.

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.

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.

Coming from a cheap $60 2.1 system, I recently upgraded my computers audio system to bx5 d2s and m-track mkII. I really like them, but felt the low end was a bit lacking as i was used to having a dedicated sub.



So I started looking around for a 10" sub with balanced connections to be paired with my 5" monitors, and there didn't seem to be many reasonably priced options. This sub seems to directly compete with 10" subs like m-audio's bx sub, krk10s, presonus t10, behringer k10s, and some others. The only problem is that all of those are ~$350-$450, with the exception of the behringer, and others didn't go down to 20Hz.



So for me, it came down to the behringer and this one. Finding the frequency response for the behringer was way harder than it should've been. An employee at BandH said in the product Q&A that it's 40-150Hz. So the frequency response doesn't go as low, it costs like 20 bucks more, and it's less powerful (180W RMS). Monoprice's sub seems like a no-brainer to me as far as bang for your buck is concerned.



Got across the US in less than 5 days. Packaging wasn't the best (plastic bag around the sub, a piece of styrofoam on all 8 corners of the sub, and inside a large box, which fit snugly inside another box) but it did a real good job. No cosmetic problems with the sub or any technical issues from what i seen so far (I've had it for a couple days now).



This thing gets loud much louder than i can imagine anyone should ever need if its being used in a home and/or studio. When turned all the way up, this thing pushes a serious amount of air out the rear port. The volume and crossover knobs make it easy to tune the sub to your liking (I have volume nearly at the minimum of -30dB and the bass is really full without being overpowering).

.

If you're looking for a fuller sound from your audio, at this price point, this definitely seems to be the best option. Construction seems really solid, so as long as I take care of it it should last me a while (assuming no component failures). That's the one thing that concerns me at this price, but I'm really happy with this purchase so far! Can't give it a 10 because nothing's perfect, but i really don't have any complaints other than my concern of longevity (which really only stems from my disbelief that they are able to sell this product for much less than competitors while still making money).

PROS: - price (why i chose this over others)

- frequency response down to 20Hz (no other subs at this price with balanced audio that can do that)

- XLR and 1/4" in/out

- powered

CONS: this is monoprice's first sub designed for use with studio monitors i believe

I upgraded from an old Klipsch 2.1 system and also purchased the monoprice powered 8" speakers and cables from monopice of course while running it all through a Tascam 2x2, all i can say is WOW.

I have been waiting to get this sub for over a year. I read the reviews and thought for such a low price I would take a gamble and pick one up. I am sure glad I did. I have compared this to my friend's Mackie Studio Sub and I find it sounds just as good. Also the ins and outs on this sub are better in that it has XLR for both In and Out. Sound quality was better than I expected. Build quality again better than expected for this price. I ordered on a friday afternoon and it arrived the next morning, a Saturday. I produce booty bass and breakbeats and this sub can handle everything I send to it. Its loud enough to rattle my house when turned up. And its not punchy but nice warm full bass.

PROS: Cost, Build Quality, Sound Quality, Volume.

CONS: None that I have found.

I recently bought a pair of JBL LSR305s and find them to be fabulous speakers. However, good as they are the woofers are only 5” and the bass can be improved.

The obvious choice is the JBL LSR310S, which has a 10” woofer and a 200 watt class D amplifier. But $400 seems like a lot to spend for a sub when the 305s are about $260 for a pair. So I started researching other options, of which there are plenty.

One little-reviewed sub caught my eye, the Monoprice 605999. Its specs are similar to the 310S, and costs $176 (about $150 on sale).

When I read the Monoprice description, I thought that perhaps Monoprice is positioning this as a low-budget alternative to the 310S. I decided to try it, feeling that I always could send it back.

So far I am very happy with this sub. It came well-packed, looks and feels really solid, and was very easy to set up.

Since I’m far from an audiophile, I asked a friend who is a musician and a recording engineer to listen to it to provide a good review for you. He describes himself as “hard to please” in audio. He’s owned and used a number of subs in his studio and as a musician, and uses the Focal CMS65s in his studio (I mention this to help you to evaluate his responses, which are below).

His comments as we listened to The Dark Side of the Moon in a very large room (25’x25’ with a 15’ ceiling), source was high-quality Spotify (320kbps AAC) through a Chromecast Audio, using two LSR305s and the Monoprice sub:

“This is astounding. For the money it’s extraordinary, it’s a great sub for the price. I’d have guessed it would cost $500 or more. It’s tight, articulate and clean. It’s musical and sounds really good. I’m going to get one to use with my Focals.”

I think it's a keeper.

PROS: Great sound
Solid build
Inexpensive
Studio quality
Works great with JBL 305s

CONS: None apparent.

This thing is a monster didn't even break in yet i've heard subs 18 inch ones like qsc kw181 yorkville behringer etc. This one is nice belive or not fills the room with bass like an 18 perfect for mastering music and also watching bass heavy movies like dark knight godzilla and pacific rim perfect subs well done monorprice.

PROS: bass heavy sound back options slot port no distortion

CONS: price lowered $50 day after i bought it. shipping 5 days

Great sub, real affordable. I need to treat my room professionally but as a replacement and temporary fix to the issue, this has been great

Was hoping this would be a good buy and it did not disappoint. It has plenty of power, so much that I couldn't image anyone turning this up to 0db. I would describe the sub as a little punchy, with a good smooth balance of lower note reproduction. The sub was VERY punchy in the beginning, but smoothed out over about 10 hours for me. I can only see it getting better.



I'm driving this with a Focusrite Scarlett 8i6 preamp, down with Monoprice TRS-XLR cables to the sub, and back up to Rokit 5 G2s with Monoprice XLR cables. I was a little worried in the beginning about the sub because I was having trouble getting it balanced with Rokits, but after a few days and fiddling with some of the monitor/sub settings, I think I found the perfect combination. I also think the sub has had time to settle and break-in. For anyone wondering about the settings I use, the Rokits are neutral except for +3db on volume, the sub is set to 2nd notch above the lowest for volume and about 85hz for low pass filter. The Rokit specs say 53hz for the lowest, but I found they roll off sharply about 75-80hz. The rest of the settings are stock. I am not doing anything to the source signal (EQ, processing, etc).



Overall the system would rival anything out there. The sub really adds a clear low end that the Rokits are missing. I'm very happy with the purchase.

PROS: Fantastic power, clarity (once broken in), unbranded front grill, and ease of hookup.

CONS: Large size

I purchased this sub to compliment my JBL LSR305's. This thing does the job. I was worried that the power of this sub would be lacking due to the low price, but I had no need to worry. This thing is LOUD, it shakes the entire room. Not only does this sub offer loud bass, but it is also very clear and punchy. So far i have no complaints, as it does exactly what I wanted it to do very well. This sub is heavy and is built nicely. If you want loud booming bass this is for you.

PROS: Nice build quality
Plenty of power
Sounds great
Removable faceplate
Fast shipping

CONS: No included foot switch

if your getting the studio monitors, get this sub. you will not be disappointed. if you have a family, responsibilities, and a budget, this is such an affordable way to get the quality you need for the price you want. i could not have realized my dream without monoprice!!!!!

PROS: boom boom boom! read the manual. it all works. period. delivery was seriously the next day!!!!

CONS: none

I recently upgraded my home studio monitors to a pair of Yamaha HS5's, and almost immediately returned them because they sounded as one reviewer put it: "anemic". It became immediately clear to me these monitors needed a sub to accompany them. But, I am on a budget and had just shelled out nearly $500 for the HS5s, and could not justify ANOTHER $500 for the HS8S Subwoofer. I waited and waited and tried to time it just right when the Monoprice Sub went on sale and fell on a "20% off" day. Finally that day arrived and I pulled the trigger for less than $200 total, including some interconnect cables and shipping. I live near the MP factory, so shipping is always a joy, usually next day. Upon unboxing and plugging in the sub, and playing some tunes thru it and the HS5s I knew I had made the right decision. The room came alive with the low end that I was missing. It sounded spectacular. Unfortunately, a few days into break-in, the right channel developed a crackling sound, which I traced back to the sub. Fortunately, Monoprice's RMA procedure was a breeze and 2 days later I had a replacement thumping away. I added a cheap "Quik Lok PS-25" pedal from Amazon to perform pypass, and boy it really helps to toggle the sub on and off to highlight the difference. I can't think of any reason to toggle the sub off other than to reinforce how awesome it sounds with it on.

this is priced a bit above what i paid awhile back, but it's still a good deal. simple, easy to configure, rocks the house.

bargain!

Nice sounding sub for a very reasonable price. Still in the breakin period, but already impressed with the performance. Using for a home music studio, pared with JBL 3 series monitors. This sub cost 1/2 the price of the JBL sub and I really can not tell the difference. Second pair of monitors is the monoprice 8" monitors. The sub goes really well with those also. Have not tested it against the spec sheet yet, it needs time to season before that.

In my recording studio, my old subwoofer needed replacing. Good low end is critical in order to get recordings to sound great. I found this on the website and noticed the professional connections on the back. It came quickly as described. Sounds great, and a great price! I highly recommend.

PROS: Pro connections on back.

Great sound.

Plenty of watts.

Relatively compact size.

CONS: none

I bought this subwoofer to go with a pair of JBL LSR305s and it's done its job really well. It definitely doesn't quite go down to 20Hz like it says in the specs, but it still sounds good and was easy to set up. My only real complaint aside from the frequency range is that it's hard to tell what the filter cutoff is set to because the numbers aren't clearly lined up with the ticks around the knob. Not a big deal, but it irked me a little.

I'm really happy that I chose to go with this over JBL's matching subwoofer because of the foot switch bypass option; it's really useful and works as advertised. It was absolutely worth the money and I'm only dinging it a star because of the useful frequency range versus the specifications.

As a reviewer here said, the sub does not go below 35Hz, but I do not think this is an issue. Also, you can certainly hear resonance out of the port. However, for the price, the filtering you get is a major advantage. My son is using this with his electronic drum kit. The fact that the satellites do not need to deal with low frequencies has opened them up and made them much louder before they clip. I think considering the connectivity, filtering, and cost, this sub is an excellent value.

Sub has much more gain than necessary. Volume control barely cracked for correct. balance with my nearfields. Sounds fine though.

I use this sub with my Tannoy ref monitors and they sound pretty damn good together. 7 months in and i'm satisfied. not here to complain about frequencies human ears can't even perceive not being present or some other ridiculous detail like that other dude lol.

I decided to replace my very old M-Audio BX8A monitors with this sub and the Monoprice 605500 5" powered monitors. Wow! What a great sound. It may not be JBL or Yamaha, but it does sound good to my ears. And at half the price. The sub produces clear and punchy bass, and as much as you could possibly need. So far i have no complaints, as it does exactly what I wanted it to do very well. Seems very well built and handles anything I've thrown at so far. Would highly recommend for any starter or even upscale home studio. Might even consider another set of 5" and start putting together a surround sound system. At these prices, that could be easily done sooner than later.

PROS: Nice build quality
Plenty of power
Sounds great



CONS: none so far

What can I say... Monoprice definitely makes wonderful/fantastic cables, and because of that, along with the great sale price and stellar reviews of this product, I ordered the 10" Monoprice subwoofer about a week ago, but after setting it up and listening to it a bit, I definitely regret it, it's one of the biggest audio mistakes I've ever made.

I admit to being somewhat of an audiophile, meaning I am an audiophile on a limited budget with high but also realistic expectations, that being said, I am hugely disappointed by this product.

The bass sound is not loud at all, I even had to check and double check to make sure I connected everything right(which I did) after putting on some music because I could hardly tell if the sub was working. Well, the blue light was on and I could feel the driver vibrating, but the sound was still really weak/anemic. I turned the volume/gain all the way up, used the phase switch, and moved the unit/subwoofer around a bit, but it made little difference, there just wasn't enough power to even be heard in my small space. And if this makes sense, when it did make noticeable, audible sound, it was very boomy and thud like, not clean at all.

I had another brand 12" sub(which unfortunately died a few years ago) costing less than $200 when I bought it, which sounded far and away superior to this product, it had much cleaner, deeper, fuller bass response, and was simply better in every way. With that I felt like I got my money's worth and more, I was pretty happy until it broke, but with this Monoprice sub, even though I got it on sale for $135 and I desperately want to return it, the return shipping cost may be so prohibitively expensive(over half of what I paid, or more) given my location that I may end up keeping it, the only thing is I'm not sure I'll be able to resist the temptation of breaking it myself, I hate it that much/think it is that bad, that it's not even worth the $135 I paid for it.

I know that being one of the few if not only negative review here my comment may be disregarded by some, and that's fine, it's your choice to make, but I would only say that you have been warned and will do so at your own peril, for I strongly feel that you will not get your money's worth and would advise anyone to look elsewhere for a better product.

I am only speaking honestly from my heart that which I believe to be true in the hopes that someone else won't be swayed by the "great" reviews here and be duped into buying this product, for if you do, whatever the expectations, you will be sorely disappointed.

Don't do it, you'll regret it.

PROS: Balanced XLR inputs and outputs(surprisingly rare on subs) which I used to connect to the Monoprice 5" Studio monitor speakers, which are significantly better by the way and I suppose I'll have to write a review on them, but for now... the pros are that the product was boxed well, taking it out was the best part, it was all downhill from there. : (

CONS: Everything else, especially the sound
