I am considering making some changes to my front speakers due to wanting to conserve some floor space in my family room. It isn't an ideal room configuration with the TV in the corner and non-perfect speaker placement. I have a Denon 891/2311 driving them in a 3.1 setup right now. The new left would go on a shelf and the new right and center would be on a shelf above the TV.
I currently have 9 yr old T45s and a C40. How much different, (or better or worse) would going with B6s and a C4 be compared to the older speakers. I also have S10 dipoles in the garage.
I am also considering Ascend Sierra-1s. (Basically, I want to get rid of the big towers and have a matched center) Any help or suggestions would be very much appreciated for this noob.
