Summary: This subwoofer kicks bottom!! As long as it is being used in SMALL room,then it is QUITE potent!I have sold and installed this in three surround systems over the years to great effect.Too bad they don't make them anymore.
Summary: I have a full Polk 7.2 setup and I have two of these incredible units. The base is crisp and clear with low distortion at high volumes. I would definitely recommend this sub-woofer to anyone looking to beef up their current setup.
Summary: I bought this sub used, in top condition I used it with my Denon AVC-2000 amp (unfiltered out) and a Yamaha RX-950 receiver which has a fixed crossover at 8o Hz into the sub out. I also had a chance to compare three subs, the Yamaha YST-SW215, the Energy EXL-S8, and the Onkyo SKW-150.
Summary: This is an excellent subwoofer and packs plenty enough punch for a small or midsize room. Don't let its size or or excellent pricing fool you or put you off. My previous subwoofer went poof and right away I did my research on the web and in stores.
