Dolby CSB115 – SLS 15-Inch Low-Frequency Screen Module
What is the Dolby SLS CSB115?
The SLS CSB115 is a mid/bass cinema screen channel module from Dolby's SLS line. It uses a single 15-inch long-excursion loudspeaker designed to deliver high-impact response behind the screen. Dolby pairs it with the SLS CS50 to form the bi-amped System 100A for smaller auditoriums.
How does the Dolby SLS CSB115 work?
The CSB115 covers 45 Hz to 800 Hz and is a passive 8-ohm cabinet rated at 450 W (60 V) AES/2 with 95 dB sensitivity. Calculated maximum output is 122 dB continuous and 128 dB peak at one metre. A powerful magnet assembly and advanced transducer technology keep the sound open and clear at high SPL.
In System 100A the CSB115 runs on its own amplifier channel with Dolby-supplied DSP crossover settings, while the CS50 mounts above it on the included steel U-bracket. An optional PXO.CS2015 passive crossover is available for single-channel operation. The cabinet has attachment points for a mid/high enclosure on top.
Construction is 13-ply 3/4-inch Baltic birch with a flat black latex finish and a barrier strip input. Drive it from a Dolby processor such as the CP950 or CP950A with a Dolby Multichannel Amplifier such as the DMA16302.
