Q: QuestionAre these to cap your subwoofer speakers?

Asked 4 years ago by Jo.

• A:Answer Hello. These backboxes are designed to work with our in-wall MC8 and XTC8 speakers. The speakers have an exposed back, so adding the backbox can help redistribute the sound waves to listeners below and help remove sound that can transfer to the floor above.
