Polk Audio PSW111
Crutchfield Customer Review (What's this?)
Had trouble with the unit not turning off when my amp was turned off, but talked to your tech people and they told me because my sub woofer wire was running up inside one wall and across my attic and down the opposite wall that it could be picking up stray voltage from electric wires inside the wall or in the attic which would signal the sub woofer to stay on. I ordered a 50' shielded sub woofer cable and installed it and it seemed to do the trick. This unit has lots of power and can shake the walls, but it is more of a boomer than a thud type of base which is why I only gave it 3 stars. I am still thinking of returning this unit.
Pros: Plenty of power, and shuts off automatically but it takes a while to shut down.
Cons: Too much of a boomer. I would rather have it be more of a thud type base
