Hi Andrew
Thanks for the suggestion -- I have experimented a bit in the past with throws and the like and can find little difference to be honest, probably because the mains are about 6-8 inches forward of the screen. The TV was actually one of the biggest sound quality improvements to the system, as the old Sony Trinitron really was just a great hulking lump of audio disturbance, looking back.
