I wanted to share a very cool setup with everyone. I just got two Buttkicker LFE Shakers (http://www.guitammer.com/hometheater_home.html), which respond to low frequency energy to shake theater furniture. My processor's main outputs are sent to my amp and from there to my full range home theater speakers. It has two sets of outputs, though, and the secondary ones I have directed to my new ICBM. I filter off everything above 80Hz and direct everything to my dual Buttkicker amps as if they were subwoofers. The Buttkickers themselves are mounted on either side of my couch, so I have stereo tactile energy along with the sound. Maybe a little over the top, but great for both movies and games.
