I don't seem to be able to balance the volume of my speakers at all. I can't get my fronts to match my centre. I've got a pair of Tannoy Mx2-M fronts and an MxC-M front. All part of the same series so surely they should match, yet the fronts, the Mx2-M's are significantly quieter than the centre. I've tested it using the test tone and to get the centre too about the same volume I have to reduce the centre by 5.5 dB, this seems a big difference for a set of speakers that should be ideally matched. Any thoughts, P.S How do you configure the delay from fronts to rears, there doesn't seem to be a test for it. I though it would do something like beep in front left/right + rear left/right at the same time so you can fiddle with the delay until you can only hear one beep.
