I own two other subs -- a nice Sony for my living room theater system, and a big Klipsch sub on my "virtual pipe organ" setup. No, this little unit isn't directly comparable to either, but it does what it does surprisingly well. I didn't buy it to shake the walls, the way my Klipsch can when I play the organ, but to add some missing heft to the music I play at bedtime for relaxation. In the bedroom, I have a small Pyle amp with Bluetooth built in, connected to a pair of rather dinky little "satellite" speakers, each one having a 4" driver and a tiny dome tweeter in a metal cabinet. They sound decent but certainly don't put out any punch whatsoever. At night I use the YouTube Music app to play quiet sedate classical or New Age Music, or very calm pipe organ music before I go to sleep. Using only the two little satellite speakers, the music is ok but not all that satisfying, lacking lower midrange and bass tones that I know are in the music (I hear them when I play the same music on my living room system). Using the supplied stereo RCA patch cable, I simply connected the "recording out" jacks of my Pyle amp to the input jacks of the sub and fired everything up. I cracked open the sub's volume control, and instantly began to hear the lovely deep tones that had been missing from my music. Not wanting to keep the neighbors up at night, I've left the sub volume quite low. I turned up the frequency knob to the point where it seems that the sub takes over the bass about where the small speakers lose it. So I'm more than happy with this purchase. It cost a fraction of what I paid for my other two subs, and while it wouldn't be adequate for the virtual pipe organ, and perhaps only barely adequate for the living room theater, it is all I need for my little bedroom music system. So I can't say that this little unit will be enough sub for everybody in every situation. It certainly isn't made to shake the walls in a big room, or even in a modest theater setup. It probably wouldn't last very long if you tried to make it do what only a larger sub can do. But for supplementing some smallish speakers in a bedroom or office system, or a desktop audio setup, it ought to be just right. It was packaged beautifully and securely, was delivered exactly on time, and everything I needed was in the box. Good product.

Just received my Monoprice 8" subwoofer and it sounds great with my Sharp XL_HF203b high fidelity stereo unit along with MICCA MB42X speakers. Just enough bass to fill in the bottom. I live in an small apartment so I can't blast out my neighbors. My living room is only 12 ft X 17 ft so this is the right size for me. My setup is less than $300.00 and I can't complain. The small almost 12" cube size is what I like. Strong bass if adjusted correctly otherwise it can get muddy. Pictured next to my book case.

I have a Monoprice Pure Tube Amplifier ... which I run through Klipsch bookshelf speakers. The idea of my system is not to shake the walls, or let the neighbors know what I am listening to. I wanted the warmest/highest quality sound, so I could play some vinyl on my Fluance turntable. While I cannot personally afford to be an audiophile, I'd like equipment which at least compliments my growing record collection in a way that stays true to the warmth and crispness of the medium. One issue with the amplifier is that it runs only 10W per channel ... which equates to about 50W. Most subwoofers these days run 100 - 300W ... so finding something in the 50 - 60 W range was tough. If you run a higher Watt subwoofer, it won't damage the system, but it's a waste of money, so this was the perfect amount for my small tube amplifier. Klipsch speakers tend to a be a little on the bright side, which can get grating. I wanted a subwoofer to give me just a small punch of bass to round out the sound and this did exactly that ... no more/no less. At first, I was suspicious that this was even working. I didn't feel any rattle on the shelves or vibrations on the floor. However, after turning it on and off while the song was playing, it became apparent that this was working and rounding out the sound nicely with some much needed lows. If you are looking for something to really 'punch' you ... the way some subwoofers do ... this is not it. If you have a smaller system with limitations on the number of Watts, it's adequate for your needs. While I do wish it gave a little more punch, it does what it is supposed to and I am not surprised in either direction as to its performance. The louder your system plays, the more bass will come out of this. As my amp isn't really designed to be played loud ... and I don't use my system's volume knob much past the 5 o'clock position, even tweaking the actual output knob on the subwoofer won't make my living room sound like a Dolby theater. This was a bit larger/heavier than I thought it would be, given its 60W performance. I own an Altec Lansing speaker set, which includes 2 small speakers and a subwoofer and that subwoofer is about 1/4 the size of this one and packs the same amount of punch. I'd prefer a Klipsch subwoofer, but given the small output of my amp, the added cost (3x what this costs) wasn't worth it to me. Where I really notice this from a sound perspective is classical music, especially with a cello. On rock and roll music, such as The Rolling Stones ... or on pop music, like The Weeknd, the lows it produces kind of blend into the music and aren't extremely perceptible unless you turn it off and on. Once you do, you'll appreciate having this. Most true audiophiles aren't fans of bass ... which is why the best speakers are on the bright/crisp side. For vocals and guitar solos, bass usually gets in the way and takes away from those parts of the song. If you are a rap music, pop, R&B fan who wants to dance along to the music, you'll likely want a subwoofer which is a bit more dynamic and less crisp. Pricewise, like the size, I think it's a little more than it should be. Given its limitations, I'd expect this to be more in the $50 - $80 range. However, there aren't many decent subwoofers out there lower than 100W, so I guess the north of $100 price speaks more to the novelty. I have owned many Monoprice products. While they in no way would ever compete with a Klipsch or B&W speaker/system, for a budget price, they perform better than generic/unbranded sound equipment. While their claims of being 'equal to' some of the bigger names in audio equipment is not really accurate, they'll give you a decent piece of equipment at a low price. Overall, I can't really sing this thing's praises too highly because it is truly not amazing ... or a difference maker. It rounds out the sound good enough to be better than nothing ... but it's not going to give you that 'floaty' euphoric feeling which true audiophile equipment might. If you have a low Watt amp, or are working in an office, or live in an apartment where you have to be conscious about the volume level, it might be just what you are looking for. If you are searching for a thumping subwoofer, it is probably not what you are searching for. I hope my honest review, after having used the product, was helpful to you.

I didn't have huge expectations for such an inexpensive subwoofer but I have been pleasantly surprised. It works just fine with my modest AV system and the sound is quite clear abd crisp. It is a nice feature to have a separate control for the crossover frequency as well as a level control. Money well spent, in my opinion.

Received unit in apparent good conditions. On further checking and to my horror the unit delivered was for 110v/60 hz power input and not what Singapore public power system operating at 230-220v/50 hz is designed for. Vendors selling internationally should have supplied dual voltage unit. Otherwise they should stick to just USA market only. I have to buy a step down transformer for my power supply in order to get it in operation. Have lodged a complaint with seller but as yet not heard back. What a disappointment.

Bueno bonito y barato.. para ser sincero detesto los subwoofer para la música.. pero para películas es fabuloso.. compre este subwoofer para mi recámara para cuando deseo ver alguna película o serie recostado. Comparado este con otro subwoofer que tengo de marca onkyo SKW-204 se adapta mucho mejor por ser compacto de 8 pulgadas. La función de autoapagado funciona perfectamente no como el onkyo que es un desastre porque pierde señal y se apaga. Suena muy bien con salidas analogas, aunque no excelente como el onkyo SKW-204 de 10 pulgadas que ese si es un bajo profundo y vivo, además que ese es construido de mayor calidad. Pero este es más económico práctico y decente e ideal para una habitación mediana y totalmente funcional. Un subwoofer nunca está de más y máximo debajo de mi cama que no estorba y sólo lo prendo para ver películas, aunque escuchando eminem suena de lujo. Es toda una ciencia el audio y cada equipo debe calibrarse de acorde a cada equipo y habitación, además que cada bocina debe usarse un tiempo para que estas se aflojen y suenen mejor.

Purchased to add bass to some computer speakers that I received as a gift. Had to daisy chain some cables in order to get everything working on my computer. The base can overpower the sound, however, there is a knob where you can adjust the bass to your liking. Would not get if you are a hard core audiophile, but I personally enjoy the difference for my set up. I purchased this through Amazon Warehouse as a resell/refurbished item. Outside of a few barely visible knicks and scratches, the subwoofer looks great, and worked well.

Hay que tomarse un tiempo para configurarlo, me tomo 3 días hacerlo, lo tengo conectado a unos altavoces activos con 1 salida RCA para subwoofer, primero utilice un conector RCA en Y y emitía un zumbido afortunadamente contaba con otro y se eliminó. aun asi no lograba que el sonido del subw destacara, por lo que decidí conectarlo a las salidas RCA (L,R) de los altavoces al subw, trate de ajustar mas o menos la perilla del crossover o freq para hacer el corte a los 80hz (que es lo que mas recomiendan los expertos) y el volumen al 60% y oh sorpresa funcionó, el sonido del subw ya destaca y se siente y ya con eso igual pude buscar una buena colocación en la habitación.

Decent for the price. Small and light-weight. It gives a fair amount of bass, but if you set the frequency control too high you end up with a constant hum, and if you put the volume too high it will rattle because of the light-weight construction. When set at the lowest frequency range and a modest volume it works quite well, giving a nice bottom-end to small bookshelf speakers. If you want to fill a large room I'd suggest a Polk PSW108 -- they are far superior to this one, although they cost a lot more, too.
