Outer Limits 4x4 Board

Greetings all , does anyone know the max size (depth) of speaker that will fit behind the grills in the barn doors. My custom draw setup dictates that the speakers must be behind the grill as the door shuts hard up against them.
Cheers

Just measure the depth that you have in the door cavity. I think due to the metal bits through the cavity you would only fit 6" speakers in the door in which case they arent very deep anyway
