Audison APBX 8 AS2 Prima Series 8" Active Sub Box with Dynamic Bass Tracking

The Prima APBX 8 AS2 active subwoofer, with 8-inch driver,features a dedicated high performance amplification module which enhances all the passive box technologies, such as the 2S² (2 Sides / 2 Sounds) design, the Plug & Play terminal block and ultra-compact size. The amplification module, with power outputs of 250W RMS is developed with he-li technology (high efficiency / low impedance), which thanks to the absence of the DC-DC voltage booster reaches the impressive 90% efficiency level, very close to the theoretical limit of the D-Class. New input stage DBT (Dynamic Bass Tracking) technology allows 100% use of the he-li (High Efficiency Low Impedance) amplifier power and to enjoy a tense and dynamic bass even at very high listening volumes. Eliminating the voltage booster was made possible thanks to the development of the new dual coil drivers, which inherit all the technological background of the Prima subwoofers, but differ for the ultra low impedance. This feature ensures a perfect synergy with the he-li (High Efficiency Low Impedance) technology, maximizing the combination of amplifier, speakers and sealed box, to obtain low, powerful and crisp frequencies. Features - Integrated 250 W RMS @ 0.4 Ω D-Class amplifier featuring he-li technology (high efficiency / low impedance) without switching power supply, for a performance next to ideal. Input stage DBT (Dynamic Bass Tracking) technology allows 100% use of the he-li (High Efficiency Low Impedance) amplifier power and to enjoy a tense and dynamic bass even at very high listening volumes. Butterworth low-pass filter at 12dB/Oct. with variable cutting frequency (50-300 Hz), phase control (0 - 180 °) and adjustable bass-boost 0÷6 db @ 45Hz. Defeatable filter to use the sub dedicated output of a bit or AP bit processor. High level audio input on multi-pin connector for maximum OEM integration and low level on RCA for aftermarket sources.
