Audison APBX 8 R – loaded 8-inch reflex subwoofer enclosure

The APBX 8 R is a shallow, loaded 8-inch subwoofer enclosure with a reflex (ported) design. Audison’s 2S² format allows the enclosure to be installed firing upward or downward: down-firing is intended to extend low-frequency output, while up-firing provides more punch and definition. A protective metal grille and levelling feet are included.

Installation and system matching

Measure the available space and account for the selected firing direction, grille clearance and cable access. Confirm that the amplifier is stable at 4 ohms and is set up for the enclosure’s impedance. This is a loaded powered enclosure with passive subwoofer only; an external amplifier and vehicle-specific wiring are required. Profound Sound can advise on amplifier matching and provide professional mobile installation.
