miniDSP 2x4 Balanced (March 2016)
In this great article, Gene goes at great length to optimize the Audioholics Showcase theater room by tuning multiple subs. A great review complemented by measurements and a youtube video. Make sure to check it out!
Bass nirvana was finally achieved in the Audioholics Showcase theater room system through multi-sub plus equalization through the mDSP device. I now have smooth, even, tight, extended bass for EVERY SEAT, not just a couple of preferred seats.
