It powers my 12" Dayton subwoofer very well. Bass seems tight and controlled. Lots of options for control except for volume. The volume level at lowest option was way too loud. I ended up facing the sub driver about two inches from a side wall and putting absorbing material on three sides. It blends well now and has nice tight bass. I do wish it could also have a low pass choice of 40 cps. I tried the speaker level inputs and it kept setting off the amp overload safety. I use a single line level input now because of the lack of volume choices. Excellent price for the power.
