Along this same thread, I have Optimus Pro77
speakers for my surrounds. They are a two-way, w/4" woofer. I am actually very pleased with their performance for this duty. I have NHT superones and a supercenter up front. I was thinking of having superzeros in back, but now am thinking that I am quite satisfied as it is. The 1050 made the Optimus speakers sound *better*.
Good luck - just thought I would put in my .02.
