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.

• 550 W RMS continuous power handling
  Exceptional thermal stability and mechanical robustness ensure reliable management of 550 W RMS continuous power, allowing sustained high-performance bass output.
• 1.5 in. (38.6 mm) CCAW voice coil (Copper-Clad Aluminium Wire)
  Combines exceptional thermal handling with reduced mass, maximising responsiveness, precision, and durability under demanding listening conditions
• Airflow Venting Cooling (A.V.C.) prevents voice-coil overheating-related limitations
  Proprietary AVC technology optimises airflow and cooling through strategically placed internal channels, efficiently dissipating heat and maintaining consistent performance at high SPL.
• Optimised for Compact Sealed Enclosures
  Engineered to perform at its best in compact sealed enclosures (21 L / 0.74 ft³), offering deep, controlled bass response even in space-limited setups.
• Protective Metal Mesh Grille Included
  Comes with a durable black mesh grille and mounting screws, providing reliable cone protection without compromising acoustic transparency or visual elegance.

The 1.5-inch Copper-Clad Aluminium Wire voice coil, coupled with an FEM-optimised 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 minimise deformation during high excursion.

The rugged die-cast aluminium 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.
