The Pulz ESM7 High Resolution 3-Way Cinema Screen Speaker System has been developed for use in prestigious large cinema environments. The ESM7 can deliver sound pressure levels in excess of 135dB with uniform on and off axis frequency response, tighter pattern control extending to low frequencies and wide dynamic range.
The system consists of 4 X 15” low frequency high efficiency drivers in conjunction with a unique coaxial Mid-High frequency driver. The 90° X 40° large format pattern control horn exhibits uniform Mid-High frequency response throughout the cinema auditorium.
The Mid-High frequency coaxial driver has been specifically engineered to overcome the incoherency of the traditional 3-Way approach due to which it delivers exceptional dialogue clarity and sound imaging, superior to the conventional Mid-High configuration.
The quad 15″ drivers are independently loaded in a direct radiator bass-reflex enclosure. This technique avoids “sympathetic failure” and provides better interface options with the amplifiers. The large port area reduces turbulence at full power output and low frequencies. A heavy duty spring loaded push type terminals ensures secure connection to the LF driver. The adjustable steel bracket allows the finer alignments of the horn to suit individual auditoriums, which can then be locked into position.
The system can be conveniently bi-amped with built in passive crossover between the Mid and High section or tri-amped using an Active Analog or Digital crossover.
The ESM7 is capable of meeting the requirement of SMPTE cinema specifications in very large auditoria.
