ESR Series
The ESR range has been developed for a particular niche in the market where an all in one box is needed to give clear detailed reproduction over a wide area. The ESR106,212, and215are three way full range enclosures with wide dispersion characteristics. They can be used vertically for theatre, church or cultural centre type installations,orin the case of ESR212 and 215horizontally mounted to give excellent coverage over a tiered seating area for stadium or grandstand type applications.
Description
Similar to our popular ES range, the ESR cabinets are fully active and driven by a proprietary amplifier, which delivers equalized, and time aligned accurate signal to each of the components. Two ESR cabinets can be driven by a single ESR High Definition Amplifier, which houses all signal processing and amplification, as well as providing control for external subwoofer cabinet configurations if required.
In situations where extended bass response is not needed but full range high definition audio reproduction with extremely good coverage is required, the ESR Range offers an ideal solution. Economies of scale are achieved by the requirement of only one ESR amplifier to run a three way active stereo system where other systems would require processors and multiple amplifiers to achieve a similar configuration.
ESR106 - Active Driven 3 Way System
The ESR106 is an active driven 3 way system employing a unique column array of multiple 6" woofers for unparalleled high quality vocal and music reproduction in challenging acoustical spaces and ambient environments. Utilising 8 x 6" woofers, 2 x 6" mid bass woofers and a single 1" high frequency driver mounted on a wide dispersion horn, the ESR106 is constructed to represent one large point source, with each part of the system positioned so that it is proportional in size to the wavelength it produces, thus the radiated power of each band remains consistent and balanced throughout the system’s overall frequency range. The ESR106 has a controlled coverage at low and mid frequencies to reduce indoor reflections. The ESR106 is controlled and driven by a dedicated ESR2600D amplifier, using KV2 Audio proprietary SLA technology.
