VR251
Overview

The VR251 has been engineered as a high output fullrange solution for a wide range of applications, from music and speech reinforcement to delay or fill coverage. The 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 VR251 a uniquely versatile solution. High acoustic output capabilities enable the VR251 to deliver clear speech and clean music to large audience areas.The plywood enclosure includes several threaded mounting points, suitable for use with either forged shoulder eyebolts or a user-supplied wallmount bracket. Optional array brackets simplify the installation of attractive flown arrays with the VRS218 subwoofer. The subwoofer has the same height as the VR251. The VR251 is available in black finish. A foam-backed powder-coated steel grille 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 five years from the date of purchase.
