DESCRIPTION

The SB products are EAW's premium subwoofers designed for the most demanding professional applications. A broad range of capabilities and sizes provide the designer with selections that can be specifically matched to their application. Top quality drivers, engineered by EAW, provide the highest output and best sonic performance possible for a given form factor. All SB models are direct radiating, with optimally tuned, vented enclosures. SB subwoofers are the choice where the best sonic performance, highest reliability, and most robust physical construction are required.

The SB48zP is a highly compact subwoofer system optimized for permanent installation. Its small size allows placement in tight places while providing the extremely low frequency response of much larger systems. While the SB48zP works well with most full-range loudspeakers, its most frequent uses are in high quality multi-media systems. These applications include: A/V systems, meeting rooms, classrooms, exhibit areas, f/x reinforcement, cruise ships, TV studios, restaurants, and small retail spaces.

The SB48zP is designed to be used with today's sophisticated digital signal processing to optimize the LF response. EAW's MX Series processors are recommended for the required crossover and equalization.

Six Year Warranty.
