The SM8SUB70 8" subwoofer system is perfect for restaurants, bars, and high-fashion retail outlets.The system utilizes a 8" woofer housed in a 915 cubic inch multi-angle, flyable, wood enclosure system to provide extended low frequency response with a wide variety of mounting options.(Not for outdoor use!).Inserts are included for use with 1/4"-20 drop forge eyebolts, optional SM8CBKT-B /-W mounting bracket.An 18 dB/octave three-pole passive crossover eliminates the need for a separate electronic network or dedicated amplification to power the speaker.Its low crossover point (120Hz) nearly eliminates localization, allowing a designer to boundary-load the SM8SUB70-B near a wall or into a corner for maximum output, while maintaining even coverage throughout the space.
