I use an Audio Control PCA in my HT. I use old Electro-Voice Sentry III studio monitors (one 15" woofer per speaker). These speakers need a little electronic LF boost anyway. I like using the PCA for movies, it gives a nice low end boost (and tactile feel) and works really well for older movies that don't have the LF of modern flicks. Use the video input. The PCA will create VERY low bass so make sure your system can handle it.
