The Prima APBX 10 AS2 active subwoofer, with the 10-inch driver, features a dedicated high-performance amplification module that 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 400W 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 (0.16 ohms for APBX 10 AS). 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. The controls section is complete and provides optimal regulation of the low-frequency emission in the car cabin. The Butterworth low pass filter at 12dB/Oct. with variable cut-off frequency (50-200 Hz) can be bypassed when used with an AP bit processor with pre-out output dedicated to the sub. The adjustable bass-boost control (0 ÷ 6 dB) at 45 Hz allows the user to emphasize the response on the lower side of the spectrum. The high-level speaker-in input on the multi-pole connector eases the integration with OEM audio systems while the low-level input on RCA is dedicated to the connection with after-market sources. The subwoofer automatic turn on/off function ART (Automatic Remote Turn-On) can be configured to be controlled by the source remote signal, by the voltage variation on the high-level input, or by the audio signal on both inputs. Phase control (0-180°) completes the equipment. The SSP (Sub Smart Plug) terminal block is provided with a single Plug&Play connector to be able to disconnect the box easily and safely.

APBMW BIAMP 2 Plug & Play T-harness provides the ability to:1. Take the front speaker output signal from the OEM head unit through the under-seat woofer connector and route it to the AP bit amplifier input.2. Separately route the signal from the AP bit amplifier outputs to the front midrange housed in the car door and to the sub underneath the seat, without the need to cut the OEM cables.The APBMW BIAMP 2 is compatible only with BMW and MINI vehicles that are not provided with an OEM amplifier. The package contains a pair of cables, for left and right channels. The cables are 450 cm long to reach the vehicle boot, where the Audison Prima AP bit amplifier is installed.

The APS 8 D is designed to deliver maximum performance in a sealed enclosure with ultra-compact volumes from 7.5 lt. to 8.5 lt. It features push connectors for ease of wiring and configurations and has been developed with a primary goal: to deliver high output in tight spaces. Output is a matter of excursion; the more air the cone moves, the more output. However reduced mounting depth traditionally has meant low excursion. Prima subwoofers employ a special cone-dustcap-basket geometry which guarantees large excursion of the mobile group, while keeping the mounting depth to a minimum. The surround and spider have been carefully designed to prevent the rocking-mode phenomenon. The cooling circuit has been designed with air vents on the basket underneath the spider, eliminating the need for vents on the bottom-plate. This allows the subwoofer to be mounted close to the back wall of the enclosure, making the most of the reduced mounting depth.
