Dolby CS131MH Mid-/ High-Screen Channel Speaker

Exceptional coverage, and amazing detail.

Utilizing our exceptional asymmetrical dual-entrant horn design, the new Dolby® CS131MH mid-/ high-frequency screen speaker delivers all the subtle detail and nuance expected in today’s immersive cinematic experience.

The asymmetrical coverage pattern — 50° vertical with horizontal transitions from 55° at the top to 100° at the bottom of the waveguide — ensures optimized volume and throws to the rear seats with gradual widening and softening coverage for the closer seats. Very articulate, uniform dialog and soundtrack can now be enjoyed in every seat in the auditorium, rather than in just a select few.

The preassembled CS131MH horn unit utilizes an advanced input plate that features a high-current, spring-loaded terminal block allowing quick, tool-free connection during installation, as well as unique flip-card PCB electrical routing for simple passive or bi-ampled module selection.

When coupled with the CS136LF low-frequency module, the CS131MH works in concert to form the Dolby System 131, a new cinema screen channel system capable of highly effective screen channel performance in large auditoriums of approximately up to 111 feet (34 meters) in depth.

Features

• Dual-entrant asymmetrical horn design allows for close driver proximity which yields improved pattern control around the crossover frequency and provides even coverage and volume shading for all the seats in the auditorium

• Quality 2” HT polymer high-frequency compression driver exhibits superb performance in the articulation ranges

• Advanced input plate featuring high-current, spring-loaded terminal block and unique flip-card PCB electrical routing, allows quick, tool-free connection during installation and easy selection of passive or bi-amp module configuration

• Composite diaphragm, 2” mid-frequency compression driver couples in close vertical proximity to the high-frequency driver, enhancing sensitivity, intelligibility, and power-handling

• Preassembled horn design simplifies setup while reducing freight costs

• Intuitive tilt and pan mechanisms can be used with laser aiming sights in the speaker horn. This provides quick and accurate aiming of the horn using a common laser pointer.

• Optional BKT.FLR floor-bracket kit (sold separately) facilitates the mechanical connection of the speaker stack to the auditorium mounting surface*
