Please take a look at the Paradigm Defiance Series Subs. Start at $400 and go to $1499. Starting at $549 they have Anthem Room Correction which can be run on an Apple or Windows PC or a Mobile Device, Full App Control of the sub from a mobile device; which allows you to find all the rattles in your room at specific frequencies by doing a "Sweep" (from 20Hz - 120Hz that you can lock and adjust in 1Hz increments) so you can isolate those things rattling at every frequency and know what frequency it is. It also allows you to hear where the dips are in the room at those frequencies. And finally, all those have wireless capability as well if you can't get a physical wire run where you need the sub to be.
