The Sound-Panel has three accessory mounting spacers available to create a professional indoor or outdoor install, where cavity depth prevents standard speaker installation.
Simply select the spacer size that suits your installation mounting depth and start your install.
Use the 16mm (5/8”) spacer to create a clean indoor or outdoor installation of the RV-FS402W(010-01790-00) / RV-FS402B(010-01791-00) Sound–Panel when the minimum wall or ceiling cavity is 25mm (1”).
