Hello Forum

Just ordered three M5HPOW for the LCR behind my 100" wide screen. The main viewing area is within the screen edges but there is seating outside the edges as well. I'm wondering about two installation items;

1. Toe-in of the L and R speakers. Should you do it with on walls? What did you use for angling spacers?
2. Tweeter height? should it be ear level or above or below.
