Audison AV 12 D2/D4 II

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

At its heart is a dual 4-ohm voice coil architecture that offers exceptional wiring flexibility. The 1.5-inch voice coil made of copper-coated aluminum wire, combined with an FEM-optimized magnet arrangement, ensures efficient energy transfer and excellent thermal management during extended listening sessions

The subwoofer is equipped with an extended profile dust cap and Radial Reinforcement Framework (R.R.F.) to improve cone stability and minimize deformation at high excursions. The robust die-cast aluminum basket is equipped with intelligent cable management hooks, while the spring-loaded clamps enable secure connections with 8 AWG high-current cables

Whether in a single-sub or multi-driver setup, the AV 12 D4 II guarantees tight, controlled and deeply responsive bass performance - true to the Audison philosophy of combining acoustic excellence with refined Italian design.


Features:

• 550 W RMS continuous power handling:
  Exceptional thermal stability and mechanical robustness provide reliable management of 550 W RMS continuous power, enabling sustained high bass performance.
• 38.6 mm (1.5 inch) CCAW voice coil (Copper-Clad Aluminum Wire):
  Combines exceptional thermal handling with reduced mass, maximizing responsiveness, precision and durability under demanding listening conditions
• Airflow Venting Cooling (A.V.C.) prevents restrictions caused by overheating of the voice coil:
  Proprietary AVC technology optimizes airflow and cooling through strategically placed internal channels that efficiently dissipate heat and ensure consistent performance at high sound pressure levels.
• Optimized for compact sealed enclosures:
  Designed to deliver the best possible performance in compact sealed enclosures (12-14 L / 0.4-0.5 ft³), it provides deep, controlled bass response even in space-constrained setups.
• Includes protective metal mesh grille:
  Included is a durable black mesh grille and mounting screws that provide reliable cone protection without compromising acoustic transparency or visual elegance.
• Radial reinforcement framework (R.R.F.):
  Integrates internal structural beams under the cone, significantly increasing mechanical rigidity and effectively reducing the risk of deformation during highly-excursive operations, ensuring consistent performance, precision and reliability over time.
• Die-cast aluminum basket with integrated cable guide hooks:
  The sturdy aluminum basket provides maximum rigidity and heat dissipation, while the integrated cable management hooks allow for clean installation even in tight spaces
• Dust cap with extended profile and VOCE II styling:
  The enlarged dust cap with the refined details of the VOCE II speaker series was developed using FEM simulations to optimize cone stiffness and structural damping.
• Two integrated cable management hooks:
  Two guides incorporated into the outer structure simplify neat and secure cable management. These hooks are located entirely within the footprint of the subwoofer and ensure compatibility with tight installation spaces.
• Die-cast aluminum basket with magnetic cover:
  Provides excellent mechanical damping, improved heat dissipation and stable airflow while maintaining structural integrity and high performance over time.
• Spring-loaded horizontal terminals (8 AWG ready):
  Side-by-side heavy-duty terminal blocks allow for short, clean wiring runs and simplified series or parallel configurations and support high-current cable connections.
• FEM-optimized magnetic circuit geometry:
  The entire magnetic assembly was designed using Audison's proprietary FEM simulation platform to precisely concentrate magnetic flux around the voice coil gap for improved efficiency, responsiveness and control.
• eID technology:
  Features Elettromedia's eID system for full traceability, product authentication and direct access to technical documentation and support.
