Audison AV 10 D2/D4 II

Compact in size, uncompromising in performance. The AV 10 D4 II is the 10-inch subwoofer in the VOCE II line. Designed to deliver fast, punchy and finely controlled bass from a small cabinet volume, its dual 4-ohm voice coil configuration offers maximum installation flexibility, while the 1.5-inch CCAW voice coil and FEM-optimized magnet structure ensure precise response and excellent thermal stability even with demanding reproduction

Despite its compact size, the AV 10 D4 II features the same advanced technologies as its 12-inch counterpart: the Radial Reinforcement Framework for superior mechanical strength, an extended profile dust cap for improved damping and the proprietary Airflow Venting Cooling System for continuous heat dissipation

Optimized for optimal performance in compact, sealed enclosures (12-14 L / 0.4-0.5 ft³), it offers deep, controlled bass response even where space is limited, making it the ideal choice for refined systems where detail and dynamics must coexist in perfect balance. Every element reflects the VOCE II philosophy: precision mechanics, characteristic bass response and unmistakable 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 completely 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.
