Focal 1028be ... what’s your toe-in?

With prior inverted dome Focal tweets I used zero.

Also, adding felt to the sides further smoothed the response. 
The key with Focal is that there are 3 conditions:
1. No center2. Center, Left and Right but little in between.
3. Smooth sound field that is seamless from L to R with no gaps.

Best,
E

totally room and system dependent unfortunately
