I am moving house shortly & DIYing a dedicated HT room. I currently have Monitor Audio RS6/LCR/RSFX and planning on upgrading to the GX range when they land in Australia. I'll likely keep the RSFX on the side walls and have capacity for a pair of rear surrounds which will give me a 7.1 setup. I'm wondering for the rear pair, would it be better to have a similar set as the RSFX or are a pair of direct radiating speakers better?
