JBL's HTI88BB Rough-In Mounting Kit is an optional installation accessory tool for JBL's HTI88 In-Wall Subwoofer. Use the kit to minimize speaker visibility and allow the subwoofer to achieve its recommended height 12" from the floor. A connections panel with push-type terminals is supplied for threading wires or banana plugs.
Recommended Height Allowance
The kit allows the speaker to achieve its recommended height 12" from the floor which aids bass reinforcement.
The height achieved by the accessory also allows the speakers to be installed in a less visible place.
A connections panel with color-coded, push-type terminals allow easy wire connection.
