Audison Voce II - AV 12 D4 II - 12 Inch Subwoofer

The Audison AV 12 D4 II Subwoofer 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.

Key Features

1. 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.

2. 1.5 in. (38.6 mm) CCAW voice coil (Copper-Clad Aluminum Wire)

Combines exceptional thermal handling with reduced mass, maximizing responsiveness, precision, and durability under demanding listening conditions

3. Airflow Venting Cooling (A.V.C.) prevents voice-coil overheating-related limitations

Proprietary AVC technology optimizes airflow and cooling through strategically placed internal channels, efficiently dissipating heat and maintaining consistent performance at high SPL.

4. Optimized for Compact Sealed Enclosures

Engineered to perform at its best in compact sealed enclosures (12–14 L / 0.4–0.5 ft³), offering deep, controlled bass response even in space-limited setups.

5. 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.

6. Radial Reinforcement Framework (R.R.F.)

Integrates internal structural rays beneath the cone, significantly increasing mechanical rigidity and effectively reducing deformation risks during high-excursion operations, ensuring consistent performance, precision, and reliability over time.

7. Die-cast aluminum basket with integrated cable-routing hooks

Robust aluminum basket maximizes rigidity and thermal dissipation, while integrated cable-management hooks facilitate clean installations even in confined spaces

8. Extended-Profile Dust Cap with VOCE II Styling

The enlarged dust cap, featuring refined detailing consistent with the VOCE II speaker range, is engineered through FEM simulation to optimize cone rigidity and structural damping.

9. Dual Integrated Cable Routing Hooks

Two molded guides built into the outer structure simplify neat and secure cable management. These hooks are entirely within the subwoofer’s footprint, ensuring compatibility with tight installation spaces.

10. Die-Cast Aluminum Basket with Magnet Cover

Offers excellent mechanical damping, improved heat dissipation, and stable airflow, maintaining structural integrity and high performance over time.

11. Spring-Loaded Horizontal Terminals (8 AWG Ready)

Side-by-side heavy-duty terminals allow short, clean wiring paths and simplified series or parallel configurations, supporting high-current cable connections.  

12. FEM-Optimized Magnetic Circuit Geometry

The entire magnetic assembly has been engineered using Audison’s proprietary FEM simulation platform to concentrate the magnetic flux precisely around the voice coil gap, enhancing efficiency, responsiveness, and control.

13. eID Technology

Features Elettromedia’s eID system for full traceability, product authentication, and direct access to technical documentation and support.
