Dolby DSR1090 – 10-Inch Two-Way Cinema Surround Speaker

What is the Dolby DSR1090?

The Dolby DSR1090 is a two-way passive surround speaker for small and medium-sized cinema auditoriums. It is designed for 5.1, Dolby Surround 7.1 and Dolby Atmos systems and performs equally well in rear-surround, side-surround and overhead positions. A 10-inch woofer and a 1-inch compression driver on a 90° x 60° waveguide give smooth, detailed response across its operating range.

How does the Dolby DSR1090 work?

Each DSR1090 runs from one amplifier channel through its factory-installed passive crossover, so it is ready to play out of the box. The 10-inch woofer covers low and mid frequencies while the 1-inch compression driver and waveguide handle the highs with 90° horizontal by 60° vertical coverage. Rated at 250 W @ 40 Vrms and 8 ohms, it produces 119 dB continuous SPL at one metre in whole space and 121 dB in half space.

In a Dolby Atmos room the processor sends each surround and overhead feed to the DSR1090 array, with low-frequency content below about 50 Hz typically redirected to bass-management subwoofers such as the Dolby 118-I-BK. Processing comes from a Dolby CP950A, and a Dolby Multichannel Amplifier such as the DMA32301 powers the array.

The top-of-cabinet input plate uses a high-current, spring-loaded terminal block with room for series or parallel wiring. Two optional mounting kits, the YK-1090 sidewall kit and the MMA-1090 multi-mount accessory kit (sold separately), cover wall and overhead installs. Dolby's finish minimizes reflection of projector and ambient light.
