Lowell SM805A
8" 70V In-Ceiling Sound Masking Speaker Assembly


The Lowell SM805A sound masking speaker ships completely assembled for suspended installation. It includes a 12W speaker with factory-wired 70V 4W transformer mounted in a 325 cu.in. backbox with grille, pre-installed wire hangers, and separate 4' chain. The installer-friendly system features externally accessible speaker leads at a single gang handibox cover with a 1/2” Romex connector located on the rear of the enclosure. The backbox and grille have a black powder epoxy finish.

Lowell's unique wire hangers allow for fast, trouble-free installation with easy positioning of the masking speaker for upward dispersion. Each pre-mounted hanger is formed of rigid, plated wire for stable, kink-free suspension from the structural deck using the Shooks and 4' chain provided. Rigging hardware to attach the chain to the deck or other building structure is to be furnished by the installer.

A six-position rotary switch with externally accessible knob is factory installed to provide a convenient method of changing transformer taps. This rotary switch is particularly useful to balance the masking speaker system.
