Atlas Sound SM8SUB70-B
Surface Mount 8" Subwoofer System - Black
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/SM8CBKT-W mounting bracket and OmniMount 30 series hardware.

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.

A premium 70.7V transformer allows the SM8SUB70 to be paralleled with any 70.7V commercial audio system to provide extended low frequency response and more overall audio impact for foreground music systems. (Unit is also 8ohm compatible). Perfect for use with other SM series full range loudspeakers Available In black (SM8CXT-B) or White (SM8CXT-W).
