1x Audison APBX 8R Prima Series 8" 4Ω SVC Ported Subwoofer Enclosure System (APBX-8R)
APBX 8 R - REFLEX SUB BOX 200mm 4Ohm
The APBX 8 R loaded enclosure was developed with reflex loading, with tuning designed to concentrate SPL in the lowest frequency range. The aim was to exploit the natural boost in output found in most cars below 60 Hz known as “cabin gain”. The 8-inch single 4 Ω voice-coil subwoofer has a powerful motor that maximizes efficiency in combination with the AP8.9 bit amplifier. The low-resonant frequency of the subwoofer, matched to the reflex enclosure keeps excursion low within the entire audio spectrum, allowing also the use with a pair of AP4.9 bit / AP4 D bridged channels, capable of delivering 260 W rms.
Features -
• Ultra-low profile (5.16 in. / 131 mm) box with slot-ported design perfectly tuned to fully exploit the APS 8 R driver.
• 2S² (2 Sides/2 Sounds) design provides the ability to choose between Down-Firing mounting to increase the low-frequency extension and Up-Firing install to obtain more punch and definition.
• Levelling feet with velcro inserts included for a secure grip with the carpet while maintaining easy removal.
• SSP (Sub Smart Plug) features both traditional push contacts and a Plug-&-Play terminal block to easily configure the impedance as required and provides a quick release.
• Rounded corners allow easy positioning in the trunk and act as reinforcement to reduce enclosure resonance.
• Special designed cone-dustcap-basket geometry which guarantees a long linear excursion capability (9 mm, one-way).
• Massive driver motor assembly, optimized with FEM (Finite Element Modeling) for perfect control under high excursion conditions.
• Water-repellent pressed paper 8 in. cone, featuring a profile developed with FEM and optimized with the Klippel Scan Vibrometer.
• Specifically developed to be combined with either the AP8.9 bit (2 CH bridged) or AP4.9 bit /AP4 D (2 CH bridged) amplifiers taking advantage of the bass boost feature and integrated parametric equalizer of the built-in DSP.
1x Audison AF-C4D Class D 4 Channel 90W X 4 @ 4 Ohms Amplifier (AF-C4D)
AF companion amplifiers are designed to add powerful amplifier channels to AF bit processor amplifiers. A plug-and-play signal input harness is included to make connection to AF bit amplifiers straightforward. AF companion amplifiers are also perfect for use with systems controlled and managed by a standalone bit processor, such as a bit One HD Virtuoso. AF companions have a “straight wire” architecture, without analog preamp functions such as crossover filtering, and are intended for use with external processors. AF M4D boasts four high-fidelity amplified channels 90W x 4 @4Ω*, 150W x 4 @2Ω* with the audiophile sound of the latest generation Audison D-Class technology. Higher switching frequencies, steeper filtering, and higher-tolerance components deliver sound above and beyond the expectation of Class D – in an amazingly compact package!
