One Systems 108/HSB 8" Direct Weather Subwoofer

Support Documentation:

The 108/HSB is a single 8" high output, low frequency subwoofer sound reinforcement system. The speaker utilizes an injection molded enclosure designed for use in direct weather applications. This product is intended for venues where additional low frequency acoustic output is required in conjunction with the 108/HTC, 108/HTH, 106/HTH and 104/HTH One Systems enclosures.
The 108/HSB may be used in outdoor installations, as well as indoor applications where extended low frequency output or additional bass response is required. The unique design of the 8-inch woofer provides an excellent combination of high sound pressure levels and low distortion.

The 108/HSB is designed for bi-amp applications only. The 108/HSB does not include an internal passive crossover.

The enclosure may be configured for either low impedance (8 ohm) operation or 70V/100v high impedance operation. Wiring instructions are found on the last page of this data sheet.
