RCC sub installation

Can the RCC subwoofer be installed before or after wall construction?

 The RCC subwoofer can be installed both before and after the drywall is mounted.

If pre-mounted (before putting up the drywall) use the small grill to cover the narrow output gap for the subwoofer.

If retro-fitted after the drywall is put up, use the grill that covers the entire cutout for the subwoofer. Both grills can of course be painted to match the wall finish.
