SUB618 is a bass-reflex active subwoofer featuring a 600W RMS Class D Power Amplifier with SMPS and is equipped with a 18” transducer.

The system delivers outstanding sound pressure levels (up to 133dB) in spite of its compact housing, while providing a clean, impressively precise low-end reproduction.
Sub 600s’ outstanding audio performance allow user to build most of the PA systems with 1 single sub and 2 full range speakers, avoiding any external processing or crossover thanks to a balanced Xover signal to left and right speakers.
Controls on the amp panel allow user to operate with Mono or Stereo audio feed, activate polarity inversion and choose Outputs link mode (True Bypass or Xover). Whenever a further punch is needed, a low-frequencies boost EQ can be set thanks to the Sub Mode switch.
The series comes with a full grille design in a lightweight wood cabinet (total weight 31kg /68 lbs) strengthened with a hardwearing, scratch-resistant black covering. Carved side handles enhance portability. The design of the top side eases subs stacking in larger systems and features a M20 pole mount thread to stack full-range speakers.
