Overview
- Designed to deliver impactful low-frequency performance in a refined, space-conscious 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 superior power handling and system flexibility, allowing for high-output configurations without compromising clarity or control. The high-density 15 mm MDF structure, reinforced with internal bracing, ensures excellent mechanical stability and damping, while the sealed design produces 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 2S² dual-orientation architecture allows both Down-Firing and Up-Firing installation, adapting to acoustic goals and available trunk space. The Sub Smart Plug terminal simplifies connections with a hybrid interface offering Plug-&-Play and push-connect options, ready for high-current wiring. Every element of the AVBX 12 D4 II is developed to express the VOCE II vision: no excess, no compromise—just deep, elegant and controlled bass designed to enhance every listening moment on the road.
