Other Generators

Voice-Masking Generator

The newly redesigned VMG-2 is a portable, direct-field, multilayered speech generator designed to enhance speech privacy in fixed or mobile locations. The unit is designed for single-point, “at the perimeter” acoustical security for sensitive conversations spoken inside a room. Built for a variety of applications, the VMG-2 is perfect for addressing single-point vulnerabilities associated with flanking path vulnerabilities often found in hotel rooms, typical office spaces, and similar locations not otherwise designed to protect speech.



Volumetric Speaker

Suitable for drop ceiling spaces, plenum spaces, and raised floors, the volumetric speaker emits an appropriate level of sound into open areas to effectively mask speech for TSCM applications.


Heavy Emitter Contact Speaker

Suitable for walls, ducts, sub-floor, doors, ceilings, and pipes, the heavy emitter can be installed in various configurations. Used in conjunction with the stud-mounting bracket, it is perfect for building in to new construction or retrofitting existing construction.


Drywall Speaker

The drywall speaker has a self-adhesive backing for use in fixed installations. It can be temporarily secured to a wall for use with travel systems by using drywall-safe adhesive tape (not included).



Plenum-Rated Speaker Cable, 18/2

This plenum in-wall speaker wire has a low-smoke, flame-retardant jacket and meets specific requirements by most state fire marshal codes. Perfect speaker wire for installation in ducts, plenums, and other spaces used as environmental air returns. 1000 ft per box. Two- and eight-conductor cables available.
