I have a whole house audio system and would like to put a subwoofer on each floor. My Denon receiver has a single Subwoofer Out jack. Is there a device or other technique that would allow me to split this signal and direct each branch to a separate self-powered subwoofer?
Something along these lines may help:

Another way to do this would be with the Aperion Wireless Audio Home Link. One sender connected to the Denon Sub out and then an Aperion receiver unit connected to each subwoofer, should solve your problem. The cost is low - $150 for a pair of send receive units and extra recievers for $79.

i know the JL Audio's let the first subwoofer act as a master and the rest act as a slave (there choice of words). so you plug the first one in from your Denon and the rest follow in a chain from there.
