More info

The S3600i offers an unheard of value in the audio industry. Dual high efficiency 18" drivers, a conservatively rated 1700W amplifier with ICEpower® sound technology, and a brand new dual opposed enclosure that relies on Newton's third law of motion to completely cancel all reactive energy. The end result is a subwoofer that extends into the single digits in all but the largest of rooms, offers vision blurring mid and upper bass capabilities, and does all of this while remaining completely inert.





  • Two, USA built, proprietary 18" drivers with powerful motor strength and efficiency.
  • Patented digital ICEpower® 1700W amplifier with DSP control
  • CNC precision cut cabinets that are finished in our industry exclusive satin black texture
  • 17Hz-200Hz +/-3dB (7Hz-11Hz typical in-room extension)





  • Ultra-low bass (20-31.5 Hz): 120.7dB
  • Low bass (40-63Hz): 132.1dB



*Subtract 9dB for an equivalent RMS 2m ground plane measurement distance.
