I'm putting together a new 7.1 system. I already have most of the pieces, including 2 Polk RTi38s (fronts), 4 Polk RTi28s (surround and rear), and the CSi40 for the center. I also have 2 10" subwoofers from my old 5.1 system that I was going to use. Now I'm wondering if the RTi38s will provide enough mid-base. My 5.1 system had pretty weak main cabinet speakers (old ~50w Technics), but they had 8" woofers in them to go along with the sub. I should be receiving my new receiver in a day or two. I have heard all the speakers individually, but never all together. I guess I'm crossing my fingers and hoping they sound good together. From the research I've done, they should. From those of you who are familiar with these components, will I be disappointed or miss any of the "mid-bass" from the RTi38 fronts? Feel free to give input or comment on my setup as well (as I can still return the speakers if I wanted to). Thanks in advance for any input. This is my first post BTW.
