So I bought a couple Klipsch rf-82s a couple months ago and I absolutely love them. That being said, they definitely have their shortcomings, particularly in the mids. A lot of music sounds great on them, but in songs where the mids are supposed to stand out (I notice it most with vocals, particularly female), they just aren't as loud as they should be, sometimes barely audible over the other instruments.
To improve the mid-range I'm considering getting a center speaker (probably rc-62, but I'll be listening to a few in-store). I already own a multi-channel receiver (Denon avr2312ci) so the speaker would be the only purchase. First of all, do you think there would be a significant improvement in the mid-range by adding a center? Secondly, is it even possible to play 2-channel music through 3 speakers? I was thinking I would use the 2312 (which has dolby pro logic iiz) to expand the stereo into either 5 or 7 channel (unless it can expand to just the front 3 channels, I'm not very familiar with dolby) and then set all speakers but the front 3 to off. Would doing this make me lose whatever would have been played from the surrounds, or would it be played through the front instead?
Any suggestions are welcome. My end goal is just to improve the mid-range sound quality, so if there is something else I could do that would have this effect I'd be glad to hear it.
