Through proven performance, the patented VT/VTF series has earned worldwide recognition for its service reliability. These cost-effective units offer compact size, functional flexibility, optimal intelligibility, effective sound distribution and high-level output. All models feature a high-efficiency compression driver with maximum acoustic conversion efficiency, a feature that reduces the number of units required to achieve specific sound pressure levels and provides substantial savings in amplifier power requirements and labor costs. The die-cast, water-sealed construction resists vandalism, insects, moisture, corrosion, and vibration during indoor or outdoor use. Selection includes a basic 8-ohm version and 70.7 or 25-volt transformer models with DC blocking capacitor (C), where indicated.

All models are finished with barrier strips. The VT series models are surface mount units; The VTF Series are flush-mounted units for recessed installation. The VT Series mounts standard 4" EO backboxes; the VTF Series mounts 4" or 4 11/16" SQ backboxes and requires Model AR or MR adapter rings respectively (order separately). Optional mounting accessories are offered and include: indoor and outdoor enclosures, a bi-directional housing, adapter plates and rings. Model color suffix: Red (R) or Neutral Gray (N) Ex: VT-157UCS.
