R4-III

The R4 Series III is a full range, three-way loudspeaker system that remains one of Clair Brothers most popular cabinets. The R4-III incorporates an innovative Directional Baffle Midrange System (DBM)^TM that creates high intelligibility. The R4-III has been engineered for optimal individual performance or in horizontal or vertical arrays.

This touring cabinet is also ideal as an installed system for clubs, proscenium theaters, auditoriums, and amphitheaters. A single 18" transducer produces solid low end reproduction. High frequency is provided by a 2" compression driver attached to a 60º x 40º constant-directivity horn, which may be rotated for several coverage options. An independently loaded midrange transducer is augmented through the DBM system.

The Directional Baffle Midrange system^TM is not a conventional horn, but an extension of the conical shape of the twelve-inch midrange transducer. The R4-III is thus able to achieve high intelligibility ("Q") without the harshness inherent in traditional horn-loaded systems.

With the introduction of this system, the R4-III delivers improved overall response, requiring no additional low frequency reinforcement. The result is smooth, transparent reproduction of speech and music program material.

Constructed of Baltic birch, the cabinet stands up to the requirements of any professional audio application. Notched extruded aluminum corners provide rigging and dolly caster support as well as added protection against corner abrasions.
