Setting up a simple HT in a spare room/"study" (former kid's bedroom). Got Sony SS-F5000 floor standers for front and CS-5000 center from ebay (sounds fine). But have pair of either Polk R15s or T15s that I'm thinking of using as surrounds. Will brand or timbre matter that much for surrounds/rears in this case? SS-B1000s are hard to find for a decent price, and I've heard are inferior in sound to the Polks anyhow.
PS Using old Yammy HTIB 8 inch sub for LFE
thanks
