The AV 12 D4 II brings the unmistakable VOCE II sound signature to the deepest frequencies, combining powerful output with absolute control and musicality. Designed for sealed enclosures, it delivers precise, distortion-free bass in compact spaces—making it an ideal choice for high-performance in-car installations.

At its core is a dual 4-ohm voice coil architecture, offering exceptional flexibility in wiring configurations. The 1.5-inch Copper-Clad Aluminum Wire voice coil, coupled with an FEM-optimized magnetic assembly, ensures efficient energy transfer and superior thermal management during extended listening sessions.

The subwoofer features an extended-profile dust cap and Radial Reinforcement Framework (R.R.F.) to enhance cone stability and minimize deformation during high excursion. The rugged die-cast aluminum basket integrates smart cable routing hooks, while the spring-loaded terminals allow secure connections with high-current 8 AWG cables.

Whether used in a single-sub or multi-driver setup, the AV 12 D4 II guarantees low-end performance that is tight, controlled and deeply engaging—faithful to the Audison philosophy of blending acoustic excellence with refined Italian design.
