The challenging task of the SW393 is to equip any high end multichannel system with unparalleled power and depth. Whilst at the same time the goal of all ADAM subwoofers has still been maintained: And that is the voluminous bass must never allow for a lack of both precision and accuracy
A 1000 W PWM amplifier drives the 15” diaphragm and works with a very strong neodym magnet and an underhang ‘long throw’ voice coil that allows for linear excitations of up to ± 2 cm.
The SW393 features a wide range of very useful and highly sophisticated controls. There is, for example, a phase switch, a level control, a high pass filter for satellite output and a variable upper barrier frequency (50-150 Hz).
