About this product

The JBL® HTi88BB rough-in mounting kit is an optional installation accessory for the JBL HTi88 in-wall subwoofer. Use it to minimize the subwoofer’s visibility and put it at its recommended height: 12 inches (about 300 millimeters) from the floor. You’ll get big, thumping JBL bass at a perfect height – but the HTi88BB won’t draw attention to itself. A connections panel with push-type terminals is included
