I?m shopping for surrounds and need some advice. I want to find the best match for my system, both in sound and appearance, and if possible, in the $75-$150 . My room is about 14x18?.

What I have so far:
-Denon AVR 1908 (7.1, 90w, HDMI 1.3, Bi-amp-able)
-RT10 fronts
-CS250s center
-PSW10 sub (not bad really for $90 to my door)

What I?m considering:
-R1?s (not on Polk Vintage)
-RT15?s
-RT25?s
-RT15i?s
-RT25i?s

Any input?
