The active subwoofer GT-SW2-HD in the first octaves, is complementing the rest of the Atohm Gt speaker range, featuring the same flowing and sleek lines and same piano lacquer finish. Within its limited volume (22l) it houses a dedicated 500W amplifier coupled to 2x23 cm specific driver units. This exceptional duo powered by the 500W amplifier is propelling the excursion up to +/-19mm (Lastest version). The strong driver motorization, the ideal charge coupled device (QT about 0.77) and the unconditional control of the signal (X-guard technology) delivers an amazing reproduction of extreme low frequencies (23Hz@-3dB) with an unprecedented speed and sound level. With these exceptional qualities and its active treatment, the GT-SW2-HD is connected in perfect harmony with the entire GT range.
