i'm getting ready to upgrade to surround sound and would like to use my 2 existing speakers (polk audio sda 2a). they are 15+ years old but in great shape (they went about 6 years without being played at all). they have the interconnect cable between the 2 speakers for "true stereo" that reportedly eliminates crosstalk distortion. can i use these as my left and right front speakers with a surround sound system, and purchase only the subwoofer, center, and 2 side speakers? if so, what would you match-up with these? they are 39 1/2" high and weigh 65 lbs. each, but i don't know any of their technical specifications (i think these are supposed to be "bright" rather than "warm"?)
the room they will be in is a "great room" 16' by 19' with a high slanted cathedral-type ceiling, and it opens up into the kitchen and breakfast nook behind it. also, the fireplace is in the center of the facing wall where the stereo and center speaker would ideally be. so everything in the front will have to be skewed a little to the left of the fireplace.
i will use the system for movies and music, but mostly music (about 90/10). i don't listen at extreme levels but occasionally i crank it up a little. for music, should all 5 speakers be the same, rather than 2 smaller surround speakers in the rear?
i'm very excited about the new sacd & dvd-a formats and plan to get a new receiver & universal player (i already have several discs but can't play them - getting itchy). i would like the receiver & player to also match up with the polks and each other (i like what i've read about the denon avr-2805 & 3805, and dvd-2900, but have been told i need a "warmer" sounding receiver, such as a marantz or h-d, for the polks)
my budget's in the $2,500 range (can wait on the subwoofer if i have to). any advice will be greatly appreciated.
