Audison Prima APBX 8 AS2 Car Active 8 Subwoofer Compact Enclosure 250W RMS OB#. WHAT’S IN THE BOX. 1 x Audison Prima APBX 8 AS2 Car Active 8 Subwoofer Compact Enclosure 250W RMS OB#. A super efficient 8? Active subwoofer, the APBX 8 AS delivers incredible bass from a compact enclosure. Rewriting the rules on impedance matching and power supply demand this musical sub bass offering is capable of astonishing performance from relatively low current draw. The enclosure can be mounted face up or face down depending on the kind of bass required and with the included bass level control you can have as much bass as you like at any time. 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). Plug & Play terminal block. The amplification module, with. Power outputs of 250W RMS. 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. Nput 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. 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 an 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 in the lower side of the spectrum. The high-level speaker-in input. 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’s 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. SSP (Sub Smart Plug). Terminal block is provided with a single Plug&Play connector to be able to disconnect the box easily and safely. Subwoofer Voice coil Ø mm in. 250 W Continuous Power 500 W Peak Power. Sub box size mm in. 386 (15.2) x 158 (6.22) x 298 (11.73). High density flux ferrite. Weight of one component kg (lb). 6,3 (13.89). Input stage DBT (Dynamic Bass Tracking) technology allows 100% use ofthe he-li (High Efficiency Low Impedance) amplifier power and to enjoy atense and dynamic bass even at very high listening volumes. Butterworth low-pass filter at 12dB/Oct. 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. 6 ART turn on function (Automatic Remote Turn-On) selectable among: Remote-in, Hi-level, Audio signal. Box with ultra-low profile 6.22 in. / 158 mm in air suspension, designedto take full advantage of the performance of the 8-inch APS 8 DLhigh-impedance driver. The SSP (Sub Smart Plug) terminal block is provided with a Plug & Play connector to be able to disconnect the box easily and safely. The 2S² (2 Sides / 2 Sounds) design provides the ability to select betweenDown-Firing positioning to increase the low frequency extension and Up-Firing install to obtain more punch and definition. Down-firing levelling feet with Velcro inserts included for a secure grip with the carpet, ensuring extreme ease of removal. Rounded corners allow easy placement in the trunk and act as a reinforcement to reduce enclosure resonances. Exclusive design of the cone, dust-cap and basket geometry to achieve a wide linear excursion (9 mm in one direction), keeping the depth required for assembly to a minimum. HRC AP remote control included. 14 Sturdy metal grille included, for a total protection of the subwoofer driver. I WILL NOT SEND OUT TO NEW EBAYERS WHO HAVE UNCONFIRMED ADDRESSES.
