At the forefront of subwoofer technology, Audison take lows to new heights with this active subwoofer. Capitalising on a class D amplifier's ability to drive extremely low impedance loads, the woofer itself utilises two low impedance voice coils offering an overall nominal impedance of 0.16 Ohms. This means the 400 Watt onboard amplifier can work with extreme efficiency offering mind-blowing bass for such a compact sub/amp combination. With both high and low-level signal inputs, the amplifier offers a built-in Butterworth lo-pass filter (12dB/octave) that can be bypassed when fed via a bit DSP. The APBX 10 AS is equipped with a quick release smart plug for easy removal if extra space is required!
