Thanks i dont yet have a SPL meter but i guess its time i took the plunge and get one.

Whats your take on speaker distances as my sony manual says about playing with the distances so you get a sense of being in the screen. eg setting the centre closer than it actually is gives a sensation of being in the screen.

Does anyone set their distances different from what they atually are and if yes why?

Also do i measure the rears from their tweeters way up the wall or just from the wall itself to my ear?

Ive searched everywhere for an answer to the last one to no avail.
