Lowell Manufacturing Company has announced the new UL-listed SM810, SM820 and SM410 Series of sound masking loudspeakers offering businesses greater conversational privacy and productivity in the workplace by adding specially shaped ambient noise to an open-office environment.
Each ready-to-install model consists of a loudspeaker (SM810: 8-inch 15W dual cone; SM820: 8-inch 50W coaxial; and SM410: 4-inch 15W single cone), factory-wired 4W 70V transformer, 760 cubic-inch steel enclosure (acoustically lined with fiberglass) with grille, and factory-mounted hangers.
Models are also available with bridge rails (instead of hangers), which can be quickly added using pre-drilled pilot holes in the enclosure.
The sound masking loudspeakers feature an SG handi-box cover with dual combination knockouts for flex conduit, and a Romex connector for installations without conduit, along with externally accessible input leads and mounting hardware (hangers with S-hooks and four-foot chain for single-point suspension or bridge rails for installation directly on lay-in tile ceiling grid).
The enclosure comes with either a black or white finish. All models will begin shipping spring 2013.
