The ESR range has been developed for a specific niche market where an all-in-one box is required to give clear detailed reproduction over a wide area. The ESR106, 212 and 215 are full-range three-way boxes with wide distribution characteristics. They can be used vertically for theatre, church or cultural center type installations, or in the case of the ESR212 and 215 horizontally mounted to provide excellent coverage over a multi-layered seating area for stadium or grandstand type applications.
Economies of scale are achieved by requiring only one ESR amplifier to operate a three-way active stereo system, where other systems would require processors and multiple amplifiers to achieve a similar configuration.
In situations where extended bass response is not required, but high-resolution full-range audio reproduction with exceptionally good coverage is required, the ESR range offers an ideal solution.
