Summary: The output for this unit is absolutely phenomenal. The dimensions of this sub is very small but it will rattle a few things. In fact, I have two units, one connected to a Denon 2112 CI and the other connected to a Pioneer Elite VSX-51. I use Monster cables on both with AudioQuest rca splitters. The clarity and quality will not disappoint -- at all. I would only recommend for medium and small rooms. For large spaces, you may want to go larger, but don't have to.
Summary: I bought this because I did not have the space in the room I wanted it for a bigger box. It has a nice sound, but its volume is a little on the feeble side. I had to trim my mains by 10db to get the kind of balance I wanted. As with all subs placement is critical, and I was somewhat limited in placement options but finally got it in the best possible spot....
Summary: This sub is exactly as expected. It will give you a good bottom end to round out your 5.1 system. I can clearly hear the base guitar, and base sax tones perfectly. Works outstanding when listening to techno dance. My room is irregular and 15 x 29 in size. I adjusted it to blend in with my large front speakers. My system is medium size and the receiver only pumps out 100 watts. My front speakers have a 8" woofer, 8" driver, 3" mid, 1" tweeter.
Summary: I originally purchased this as I read the specs and know the companies reputation. That being said I purchased it for my bedroom which is about 13x18. A good size master for my average 3 bed to bath. I was pleased with it's depth and just wish it had a little more bass. I should have gone with an 8 inch not a 6.5 with an 8inch passive. Or maybe even a 12 as I am an audiophile who searches for perfection at a reasonable price for my budget.
Summary: I have this sub attached to a Denon AVR-1610, along with a pair of BIC DV62 F/L and a BIC Center speaker, and it sounds great whether you're using it for movies or music (for rap music, it sounds awful no matter how much you adjust, but I don't listen to it anyways, so it's no bother to me as I was just testing all forms of music on it....
Summary: I bought this to enhance the sound of the ceiling speakers in my 3 season room. I wanted something small that would fit under a table or love seat so my choices were limited. I first tried the Yamaha FSW-050. The size was perfect but the love affair ended there. It was very boxy sounding and had no adjustable crossover. I could not get it sounding to my liking so I decided to return it and purchase the Velodyne Impact-Mini.
Summary: I just bought a house and had a room with surround speakers built into the ceiling, but needed left and right speakers and a good sub to go with my TV. Ended up purchasing a pair of the Orb Audio MOD1 speakers (two thumbs up there as well) along with this subwoofer. Not sure if a center channel would be justified as the speakers are sitting on a 48" tv stand (not a lot of separation). This sub is very well made and I am pleased with the bass that it puts out.
