I'm to the point of installing my in-wall speakers in my HT and need to decide on a screen. It's a front projector set up I can have the center channel slightly off-center left to right and above the screen. It's tweeter is "focusable" to aim it at the seating area. In this configuration I can use a retractable screen OR I can spend more $$ for a permanent mounted micro-perf screen. In that case I can have the cc exactly in the middle of the screen at seated listening height. Aesthetically I prefer the former. Any experience with how much better the sound location will be with the latter? Thanks!
