Rated 5 out of 5 by from Great sub for the money!There really should be nothing to complain about for the price paid $75. It sounds great and does the job. My rock records sound great again. Matches well with all types os speakers.

Rated 5 out of 5 by from Combined with the BOSS BG300 Digtal Bass ProcessorI now have full control over the sub using a BEHRINGER 802 mixer and the Boss BG300. Used a Radio Shack 3amp 13.8 volt power supply to run the Boss. Did have to place the sub on a table because I live in an apartment building but at lease it is concrete thank god. The sub works too well now no muddy or disstorted sound just super pleasing clear tight bliss! I can't even bring the vu meter to the zero level and stay flickering at the 20 mark. For 125.00 dollors the combo is not beatable anywhere. Thanks Joe Mal Your Music Pal

Rated 5 out of 5 by from Perfect for my needs.This little 8" sub is perfect for my small apartment. If I had a more powerful one, I would just have to turn the gain down on it. I have the gain set to about 50% on this one as is. Pumps out a lot of bass, depending on what type of music I play. I like many genre's so it varies a lot for me. For Reggae and most Blues, it definitely improves my listening experience. R & B tunes sound great as well. On some Rock & Roll songs you can barely tell it's there, but that is just how it is recorded. I set the crossover to the voice of Johnny Cash, so the singing don't come through the sub. Then I set the gain to blend in with the speakers. I love it. Glad I didn’t spend a pile of cash on a sub. The money I saved on this subwoofer will go towards a pre-amp.

Rated 5 out of 5 by from Still Trying to Find a FaultI bought this to supplement a set of very expensive Audio Physic Brilon 2.0s I inherited. I wasn't expecting much and essentially purchased the sub just to see if a sub would be the right avenue to go with these mini monitors. While it did take me a second to get the levels and positioning of the sub perfect, I can't not reasonably distinguish where the sub ends and the speakers begins. It's perfectly integrated with my Audio Physics and YBA Amp. Accurately digs deep enough for Boards of Canada and Flying Lotus, while still being musical enough for the round airy bass drums of David Brubeck and Terry Reid recordings. I can't really find a reason to upgrade at this point. Please keep in mind that I am in a very small room with a modest speaker and amp system. I'm not sure that this is the way to go for your large room theater set up, but I can wholeheartedly recommend this sub for any small room/mini monitor set up. It's good enough to hang with a $3000 set of German mini monitors!Also it did take a few weeks of listening before the sub really came to life. It was a bit flabby at first but now it's fast and musical. For $89.99 I can't imagine a reason not to at least try it. A great product all around. I'm very very happy.

Hi I have a home theatre system speakers connect to an amplifier but without a subwoofer can I connect this subwoofer to the amplifier with the speaker wires????

Question about the high level inputs and crossover, when using the high level inputs is the output full range or is it determined by the crossover settings? Eg: if I set the sub to 150hz will the speakers only get 150hz and up or will it be full range?

Asked by: scoobnz
No, the high level outputs are a full range pass through so the crossover will only effect the subs low pass.

Can the feet on these be replaced with carpet spikes?

Asked by: blankman2g
Yes, but they cabinets will need to be drilled to accommodate spikes since the included feet are mounted using standard wood screws.

My amp is the SMSL SA-60 and my speakers are Klipsch Reference which are 8 ohm speakers. Can I run speaker wires from the SMSL SA-60 to the subwoofer speaker inputs, then run speaker wire out of the sub to the Klipsch speakers? Can my amp handle the load?

Asked by: ponsonby
Yes that connection will work fine. The subwoofer amp does not introduce a load to the amplifier, it will only see the normal load of the speakers.

Does this subwoofer requires an amp for non-powered speakers?

Hi, I have a 1990's Onkyo TS-822 receiver with speaker outputs. Can I connect my speaker outputs to the sub's hi-level inputs? I would then hook the outputs to my two bookshelf speakers. 

Asked by: muzikloverct
Yes that is the correct way to use the speaker level inputs and outputs on this subwoofer.
