Key Features
  • Passive Design
  • 8" Long-Excursion Woofer
  • 150W RMS Power Rating
  • Integrated 60W Transformer
The black Atlas Sound SM8SUB70-B is a passive surface-mount subwoofer with a multi-tap transformer designed to deliver reliable low-frequency reinforcement for foreground music systems in waiting rooms, offices, retail stores, restaurants, and more. When driven by your 70.7V, 100V, or 8-Ohm power amplifier (available separately), this subwoofer provides a power capacity of 150W RMS. The SM8SUB70-B is equipped with an 8" long-excursion woofer capable of covering the low-frequency range from 55 to 100 Hz.

An internal 18 dB/octave crossover at 125 Hz ensures proper input bandwidth, and the high-efficiency 60W transformer accommodates a range of power taps. Fuse protection for the driver inhibits damage from overloading. The small-format wood enclosure is flyable via 1/4"-20 inserts, and features an input panel with a barrier strip and two parallel 4-pole speakON inputs.
