Description
Compact size, uncompromising performance. The AV 10 D4 II is the 10-inch subwoofer from the VOCE II line, designed to deliver fast, punchy, and finely controlled bass in smaller enclosure volumes.
- Dual 4-ohm voice coil configuration offering maximum installation versatility
- 1.5-inch (38.6 mm) CCAW voice coil for lightness and optimal conductivity
- FEM-optimized magnetic structure ensuring precise response
- Excellent thermal stability, even during demanding playback
- Advanced technologies identical to the 12-inch model despite the reduced footprint
- Radial Reinforcement Frame (R.R.F.) for superior mechanical strength
- Extended profile dust cap for better damping
- Exclusive Airflow Venting cooling system for continuous heat dissipation
- Optimized for compact sealed enclosures of 12-14 liters (0.4-0.5 ft³)
- Deep, controlled bass response, even in limited space configurations
- Ideal choice for refined systems where detail and dynamics coexist in perfect balance
- 16.8 mm linear excursion (Xmax) for significant air displacement
- 20 mm mechanical excursion (Xmech) for extreme performance
- Polypropylene cone for fast and controlled response
- Fiberglass former for thermal and mechanical resistance
- High-flux density ferrite magnet (134 x 55 x 36 mm)
- Die-cast aluminum basket for rigidity and heat dissipation
- VOCE II philosophy: precision engineering, characteristic low-frequency response, and incomparable Italian design
