Application:
tHigh quality oor monitoring applications
tVery low dimensions, SPL and high quality sound
tIdeal for TV studios and theaters
Description:
The ESM26 is a full-range low prole 2-way, passive 2x 6” monitoring solution. The ESM26 features a
revolutionary passive delay line which dramatically reduces feedback and the same 1.75” NVPD
compression driver as used in the EX series. Designed to withstand the rigours of live performance,
the ESM26 features a sturdy steel grill, and a specially designed acoustic fabric protecting the
compression driver. All housed in a stage ready wedge shaped cabinet the ESM26 is truly one of the
most impressive monitoring solutions on the market.
The ESM26 is dedicated as a oor monitoring system (half space area). It is designed according to KV2
Audio's philosophies and oers enhanced dynamic range, increased resolution and high output with
exceptionally low distortion factors. The ESM26 has a balanced frequency response and exceptional
phase characteristics achieved by its electronic and acoustic design.
The balanced phase characteristic is achieved by means of a unique dividing network containing a
revolutionary passive delay line. The ESM26 also boasts electronic protection and monitors the
maximum signal, thermal level. The woofer and tweeter are protected by a reverse thermal-circuit
breaker (autoreset).
The ESM26 features a professional Baltic Birch construction with a wear resistant polymer coating and
a specially designed handle for simplied carrying and handling. ESM26 is also available in any RAL
colour.
Connection:
The ESM26 features two Speakon (NL4) connectors. The connectors are interconnected in parallel to
allow the “daisy chaining“ of additional ESM26's.
