It's been suggested to me that the best tower match for my Polk CSi30 center would be the RTiA's, as far as tonal and timbre cohesion (I have been looking at a new set of floorstanders to replace my R20 bookshelves for the new house).
Just the other day, I found a great deal on RTi8's from OneCall.com and then realized that these are from the slightly outdated "RTi" series, not the new "RTiA"...my question now is, does anyone know if just the newer RTiA's must be used with my CSi center, or can an older RTi be used, and what is the difference between them?
