dB Technologies Sub-618

The SUB618 is an active bass reflex subwoofer featuring a 600 W RMS Class D power amplifier and an 18" driver. Despite its compact cabinet, the system delivers outstanding sound pressure levels (up to 133 dB) and offers clean, impressively precise low-frequency reproduction. The excellent audio performance of the Sub 600s allows users to set up most PA systems with a single sub and two full-range speakers, avoiding any external processing or crossover thanks to a symmetrical Xover signal to the left and right speakers.

With the controls on the amplifier panel, users can work with mono or stereo audio input, activate polarity inversion, and choose the linking mode of the outputs (True Bypass or Xover). Whenever an extra punch is needed, a boost EQ for low frequencies can be set using the Sub Mode switch. The series comes with a full grille design in a lightweight wooden cabinet (total weight 31 kg), reinforced with a durable, scratch-resistant black cover. Sculpted side handles enhance portability. The top design facilitates stacking subwoofers in larger systems and features an M20 pole thread for stacking full-range speakers.
