SR-110B 

Surround Loudspeaker

Introduction

The SR-110B 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-110B 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-110B features a high power long-throw 10” (254mm) low frequency transducer 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 fre-

quency coverage. The 200 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-

110B. 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 system.
