Hello all...I need some advice. About 6 months ago I bought a pair of LSi25's for two-channel use only, but with the intention of setting up a home theatre system when I could afford it. With that in mind, I recently purchased a NAD T763 reciever and I also have a Sony DVD/CD/SACD player (don't remember model number). Well, it turns out that I really want to invest in a home theatre system now and would like it to be all LSi series. So I was thinking of adding a LSiC for the center and a pair of LSiFx's for the rears. Does this sound like a reasonable set up? Do I need to get a seperate subwwofer since the 25's have a powered sub? Can I mount the LSiFx's onto a wall? I didn't notice if they have that capability. Thanks for the advice.
