After talking with Def Tech (about too much power for the surrounds) and others in these forums I am running the 950/755 with so much pleasure. I use 3 2300CLR's across the front due to built-in cabinet situation and BPx surrounds. These speakers thank me everyday for the extra power. I am wondering from anyone if you think I will hear/feel a great difference with a separate sub since I now only use the subs in the 2300's all set to "large"?
