AVBX 12 D4 II Subwoofer Box | Passive Sub Box | 300 mm | 1100 W

Designed to deliver impactful low frequencies in a refined, space-saving format, the AVBX 12 D4 II combines the full authority of a 12-inch VOCE II subwoofer with an ultra-compact sealed enclosure optimized for modern vehicle interiors.

Equipped with the AV 12 D4 II driver, featuring a dual 4-ohm voice coil, the enclosure provides excellent power handling and great installation flexibility, enabling high-output configurations without compromising clarity or control.

The 15 mm high-density MDF construction, reinforced with internal bracing, ensures outstanding mechanical stability and damping, while the sealed design delivers tight, extended bass with natural decay and definition. Engineered for true musicality, the enclosure reproduces every nuance of the low-frequency spectrum with depth and precision.

Its dual 2S² orientation architecture allows for down-firing or up-firing installation, adapting to acoustic goals and available trunk space. The Sub Smart Plug terminal simplifies connections with a hybrid interface offering both Plug & Play and push-connect options, ready for high-current wiring.

Every element of the AVBX 12 D4 II has been developed to express the VOCE II vision: no excess, no compromise — just deep, elegant, and controlled bass designed to enhance every moment on the road.
