Rooze...I use CarverPro zr1600 amps for my subwoofers, and they certainly do the job. One advantage, for a SW, of the zr1600, or any digital amp, is that their efficiency is very high. Much music has no signal content in the SW range, and where the music does have such LF content it is usually only for a small portion of the time. Digital amps draw almost no power when there is no signal.
