I have a similar layout and run 30' Coincident CST 1 speaker cable and shorter IC's...any issues I've had to deal with have not been speaker cable related...if I ever get monos or a different room with different layout possibilities, that could change
Cable Distances
Due to room layout my speakers will be about 30' from my equipment rack. My question is; should I run 30' of speaker cable or is it better to invest in small monoblocks placed behind speakers and run 30' of interconnect cable from a preamp.I only have the speakers for this system ( Apogee Centaur Minors) so amplifier selection is varible.
