712 Cubic Inch, 8" Masking Speaker System, White

OUR PART #  M1000-W

The M1000 masking speaker assembly is designed to accurately reproduce the required spectrum of masking signal into the plenum space. The innovative 734 cubic inch square enclosure ensures ample low frequency response. A specially designed 8" dual cone loudspeaker is included in the package. A high efficiency 70.7V internal transformer is coupled to an external tap selector switch for easy system tuning.
The exclusive Atlas Sound EZ hang brackets simplify installation. This innovative suspension system utilizes (2) collapsible plated hangers configured to allow quick upward, downward, or side firing installation. The hangers are factory-installed on the unit and fold flat for shipping. To meet most any local code requirement, the M1000 includes an innovative cover containing both knockouts and a strain relief. This system will allow the use of rigid or flexible conduit (if required) and easily accommodates "through" connections on the removable plate. UL 2043 listed for use in air handling spaces.
