audison APBX 8 RThe 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 ohm voice coil subwoofer has a powerful motor that maximizes efficiency. The low resonant frequency of the subwoofer, matched to the reflex enclosure keeps excursion low within the entire audio
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 ohm voice-coil subwoofer has a powerful motor that maximizes efficiency. 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 AF C4.10 bit/AF C4D/AF M4D 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 AF bit and AF D amplifiers
- Sturdy metal grid included for a total protection of the subwoofer driver.

Exact fit, no trimming needed
Style: One Piece
Ordered this for my Ford F-150 and it dropped right into the airbox perfectly — same dimensions as the OEM filter, same end seals, same fit. No gaps, no air bypass around the edges. Clean swap in under five minutes. Engine runs smooth and the price is unbeatable.
