Class D amps were first applied to battery operated systems that needed maximum efficieny to extend battery life. Think hearing aids and cell phones. Subwoofers were next because the circuits available at the time didn't allow fast enough sampling to operate over the entire audio band, but they could make a decent bass amp that didn't require much of a heatsink, which is a large, expensive part. Now there are full audio bandwidth class D power amps available (TI and other make ICs, Tripath, modules, etc.). Expect to see more of them and fewer analog amps as time passes.
