Hi everyone. Just got the ff: M22Ti fronts, VP150 center & 3 M2i rears. Need advice on best placement:

1. M22Ti - How high should I position them relative to ear level at viewing/listening position and relative to the TV screen (JVC AV-48WP30).

2. M2i - I will wall mount these about 4-5 ft behind viewing/listening position. How high should I place them?

And while we're at it, can anyone tell me where eye level should be relative to the tv screen for optimal viewing?

Appreciate any feedback. Cheers!
