I've always been a fan of multi-speaker set-ups. In another life I had (for 30yrs) a Marantz Model 19 with a pair of Large Advents on each side. Don't think I ever had it past half volume. Afraid neighbors two blocks away might complain. That system took a lot of space. One day I decided I wanted to have BIG sound but have the system disappear into the room. These Pioneers fit the bill. The sound from 3 is greater than 1. The 2 at center, well, that was to compensate for the 6 up front. The Sub. Believe it or not, at these settings, No Boom, no distortion. Plenty of UMPH! The challenge was to get this little sub woofer to be seamless with all these speakers and fill this 4800 cubic foot space. It worked! Music presence is awesome. Surround sound is really good, but for MUSIC I like the sound of 2.1 and when alls adjusted, 5ch all stereo with center off. You would'nt know the surround mode was off. By the way, I sold the 19 but still have the Advents out in garage.
