These rough-in kits are designed to expedite installations as well as deliver higher overall performance and customer satisfaction. Thanks to its super resilient and fire retardant plastic, which is over ¼" thick, the RK back box significantly reduces musical over-hang that is found when speakers are installed in double-sided walls (walls dividing multiple rooms). This newly designed back box snaps easily to the rough-in kit and enhances speaker performance by utilizing given air space, delivering clear and clean sound quality.
