Has the ever been a What HiFi review of in wall speakers - I can't seem to find anything in the archives! I'm building a new extension and was considering 3 B&W CWM 6260 Front and centre built in to the TV cabinet and then using B&W M1 Rear speakers. With these I was considering the REL Quake.Only problem is that it seems impossible to actually test this set up out - noone seems to have any that I can listen to. Is it ok to mix and match like this? Any advice? FYI am considering use with Onkyo TX SR 875 (after the recent test - looks awesome!) and Pioneer PDP 508XD. Will also use for music via the Onkyo and a Sonos Setup. Big thanks you for any light you can shed on the question.
