I've wall-mounted my MA RXFX surrounds with centre of speaker at 1.6m. Sat on my new sofa(bed) my ears are about 0.9 - 1.1m depending how much I slouch. The front RX6 tweeters are at ear-level in a normal seating position and I've angled the centre up to ear level as it sits on low stand below my screen. Does that sound too high for the surround speakers? Used to have them on stands at ear height (in previous room) and that was too low I'm sure, but now I'm worried I've gone too high!
