rc-7 vs rc-64 whats the difference between the 2

[pietsch288]

I have rf-7 mains and a rc-7 center and I small treated room (15.5 x 23 x 9.5) My receiver is the denon 2808 and I use audyssey flat. I can hear most of all the detail. I feel like during action scenes the center gets a little loud but I need to leave it at or close to the same volume so I can hear the dialog. I did borrow one of my buddies rf-7's and tried it as a center and liked the actions better (seemed alot smoother) but the dialog was a little too laid back plus I can't leave the center standing in the middle so I would have to lie it down and rearrange the face like a center channel and that way too much work also my center is above my screen and an RF-7 is really heavy. So my question is.......rc-64-is it smoother than the rc-7 while keeping the dialog "up front". thanks rich
