DESCRIPTION
The VR51 has been engineered as a high output full range
solution for a wide range of applications, from music and speech
reinforcement to delay or ll coverage. Two horns are included with
each VR51: the factory-installed low Q horn can easily be rotated or
replaced with a high-Q horn as needs dictate. The ability to select
among four coverage patterns with either vertical or horizontal
mounting makes the VR51 a uniquely versatile solution. High
acoustic output capabilities enable the VR51 to deliver clear speech
and clean music to large audience areas.
The cross-ply laminated birch enclosure includes several threaded
mounting points, suitable for use with either forged shoulder
eyebolts or a user-supplied OmniMount 120.0 Series wall mount
bracket. The VR51 is available in either black or white nishes. A
foam-backed powder-coated steel grill protects the drivers. The
entire loudspeaker is fully tested at the time of manufacture and is
warranted to be free from defects in materials and workmanship for
a period of ve years from the date of purchase.
