I'm currently upgrading a 5.1 system to 7.1 and am interested in feedback from people that have struggled with the same decision as me i.e which speakers to use for the side/rear! Currently my system currently comprises (or will shortly when Bryston get their act together): Processor/Amplifier: Lex MC-12 / Bryston 9B / 4B Front: IMF Professional Monitors (Huge Monsters but I would never part with them) Center: B&W LCR60 S3 Rear: Currently B&W 2003's but these will shortly be re-allocated so I will need four speakers. Since the back of my room has a double glazed patio door, I am resricted to mounting the the rear speakers close (12") to the side wall rather than the preferred position of 4 ft apart from the room centre, I could mount them in the ceiling but downward firing would probably sound strange. Fortunatley I have no restrictions on the side speaker position. Since I can never match the front transmission line IMF monitors should I concentrate on making all the side/rear speakers the same tonal quality? B&W appear to have discontinued their dipole speaker range due to poor sales, seems that most people apparently prefer standard radiation pattern! Does anyone have experience with a similar configuration?
