Hi all. Ive got a Denon AVR-1909 hooked up to a set of Tannoy SFX 5.1. The centre speaker that came in the box sounded a bit rubbish, and after reading a lot of info on tinterweb about the centre speaker on the tannoys, upgraded it to a M.A R180HD. A chap on here last night mentioned i should have all 3 front channels same make ie monitor audio to create seamless soundstage. I can get 2 pairs of the small 45's for fronts and rears. But ive also been thinking of getting a pair of M.A BR1 bookshelfs to reolace the 2 fronts and keep the rear tannoys. Or do I get the BR1's for the front and get the radius 45's for the rear!? Confused.com!!
