Input:
at 1/3rd of what I expected to pay, I got what I needed. I use this as a 6th channel subwoofer for a dts receiver without a 6th channel amplifier. I agree with the other reviewers, simply leave the unit on 100% of the time  unless you go weeks without using, the on/off auto position is to be  avoided at all costs. I have not had this unit distort at all even when I  tested it at higher than needed volumes. I'm glad I passed on the larger  KLH models as this is all I needed.
