Polk Audio DSWPRO 550wi 10" Wireless Ready Subwoofer Each

Sounds great. The remote gives you several placement options that will affect sound quality. Also, it's nice that the sub automatically comes on when the a/v is engaged and automatically turns off when not in use

I would like an Ipad app to controll the volume and features

Remote a plus when speaker located out of easy reach. Plenty of power to shake the average home. Good clarity at high volume

Would be nice if it came with a grill
