Aaron,
You made an excellent choice.. I've had a 20-39PC for around six months. Hahahaha you better get some velcro tape now and start securing things down now.
I have a 20-39pc, Titans, cc-170 and Energy Take2's for surrounds. The single, powered sub provides MORE than enough bass in my living room. The Haunting (dts) is obscene, the THX intro on the Phantom menace ..oh yea! I upgraded from a Paradigm pdr-10 ..OMG what a difference! Enjoy!
