WR Series

The WR series products offer flexible system configuration as well as special treatment for weather resistance and extended durability in extreme environments.

The WR (weather resistant) series expands with a compact subwoofer designed to provide extended range for the WR series full-range cabinets. The WR-151SCX incorporates a single 600 Wrms 12″ loudspeaker. The WR-151SCX offers identical cabinet dimensions as the WR-6415DXW for easy combination in tight packed arrays. Threaded rigging points and optional mounting hardware are available.

The WR-151S offers two exposure ratings: CX (covered exposure) for applications where cabinets are covered or protected, and DX (direct exposure) where cabinets are unprotected and directly exposed to the environment. The CX versions are protected with a thick ISO-flex polyurea coating on the exterior surface. The DX versions augment the protection rating by employing a fiberglass exterior. Stainless steel fittings and mounting hardware are offered on both versions.
