I recently had the opportunity to buy 2 sets of Paradigm Reference SA-10R in-wall speakers for $150 each set, brand new. I want to put together a 5.1 surround sound system utilizing at least 2, and maybe all 4 of these speakers. Right now... all I have at home is a pair of NHT Super Ones that I use for music, etc. My questions is.... should I get rid of the Super Ones and use the 4 SA-10R's as my fronts and backs (and then obviously get a center and sub later)? Or should I keep the Super Ones as my fronts and just use one pair of the SA-10R in-wall speakers for my rears? I can always just sell the second set I guess. Any input would be greatly appreciated. Thanks.
