Sonance - VP82 RECTANGLE - Visual Performance 8" 3-Way In-Wall Rectangle Speakers (Pair) - Paintable White

Hi, Thank you for your question. I apologize; I'm not sure I fully understand your question. These speakers mount to the drywall wall using tabs we refer to as "Roto-Lock clamps" These clamps will automatically rotate into position and begin clamping the speaker to the drywall by turning screws that are located on the front of the speaker. We do not offer a back mounting plate as an alternative mounting solution. If you are asking about a backbox for the speaker or sound enclosure, we have an optional retrofit backbox that can be added to the speaker to minimize sound transfer. This accessory can easily be added to the back of the speaker during installation.
