Bass-reflex active subwoofer from SUB 600 series that features a 12” woofer with 2.5” voice coil and a 600W RMS Class-D power amplifier with SMPS, delivering outstanding sound pressure levels (up to 129 dB) in spite of a very compact housing and provides an impressively precise low-end reproduction. Its remarkable audio performance allows 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 separate balanced X-Over signal feeds 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 X-Over). Whenever a further punch is needed, a low-frequencies boost EQ can be set thanks to the Sub BOOST Mode switch. The cabinet of the loudspeaker is made of black painted plywood with one top handle and a M20 pole mount. Frequency response: 46 - 123 Hz. Max SPL: 129 dB. Dimensions: 360 x 550 x 525 mm. Weight: 19,8 kg.
