In the living room we use a pair of KEF KC62s that integrate with LS50 Wireless II speakers controlled by an a KEF app that runs on an iPad. Each speaker has an output to a sub. In the media room we use a pair of Velodyne SMS-1s that take LR output from an Ayre KX-5 Twenty preamp and send room corrected output to one of a pair of HGS-15s. I'm not sure about the stereo contribution of the subs, but pairs of subs are certainly effective.
