Loaded with a 15" neodymium speaker in a precisiontuned bass reflex housing, this professional-grade subwoofer delivers powerful, direct and remarkably dynamic response. The cubeshaped enclosure is made of 18-mm birch multiply coated with black or white lacquer. Other RAL colors are optionally available. A rugged steel grille backed with laminated acoustic foam rubber protects the front.

Frequency response ranges from 47 Hz to 150 Hz (+/- 3 dB), with 102 dB axial sensitivity @ 1W/1 m under half-space conditions and 135 dB maximum SPL at 10% THD under half-space conditions. Power handling is 600 watts RMS.
