I am thiking of getting this speaker for surround duties. Does any body have any opinions. The reason i'm after this particular one is to match the b&w cdm 9nt and cdmnt centre. Will be using kef q55.2 for rears. Currently i am running my speakers through a roksan kandy anmp which is connected to a yamaha dsp e800, this processor will be upgraded, cant make up my mind as yet what to go for. Any help on the ds7 will be apreciated, cant seem to find that much info on it. I will be demoing it, which i know is the only way to decide, but opinions will be apreciated thanks in advance. The sub duties are carried out by a servo 15.
