SR-26Surround Loudspeaker

Introduction

The SR-26 Cinema Surround Loudspeaker offers high power handling, excellent sensitivity, and extended bass response in a very compact enclosure. The high power handling and rugged plywood enclosure are optimized for the task of digital soundtrack reproduction.

Instead of being tuned as an individual unit, the SR-26 features Array Optimized Tuning (AOT). The crossover is voiced for flat low frequency response when used in an array on a theatre wall. Conven- tional loudspeakers are voiced as a single unit.

The SR-26 features two high power long-throw 6.5” (165mm) low frequency transducers for smooth, extended bass response. The high frequency section combines a 1” (25mm) titanium diaphragm com- pression driver with a constant directivity horn for very high output capability and wide, even high frequency coverage. The 150 watt continuous power rating provides absolute reliability.

The compact black enclosure with black grille blends into any theatre decor. The baffle’s built-in 15° tilt places the loudspeaker at the optimum coverage angle for most applications. The Quick Mount bracket design allows for fast installation. The loudspeaker-half of the bracket comes pre-installed on each SR-26. The Quick Mount wall bracket is purchased separately to allow shipment to the job site ahead of the loudspeakers. A U-bracket is also available in lieu of the Quick Mount bracket sys- tem.
