ESR 215 S

The Ultimate, Full Range, Large Scale System, Slim version

The ESR215S is a slim version of large scale full-range 3-way loudspeaker system with a wide horizontal dispersion of 110 degrees. Designed for use with the ESR3000MkII tri-amplified stereo electronic control pack, the ESR215S loudspeaker system features two 15" woofers, an 8" mid-range driver, and the same large scale NPVD 3" compression driver found in KV2 Audio’s VHD mid-hi enclosures. With a wide and smooth frequency response, the ESR215S is ideal for theatre or stadium applications. Like the ESR212, it incorporates multiple M10 fly points, and various brackets and flyware are also available.
