Product Overview

The AV 10 D4 II is the 10-inch subwoofer of the VOCE II line, designed to deliver fast, impactful and finely controlled bass within reduced enclosure volumes.

Its dual 4-ohm voice coil configuration offers maximum installation versatility, while the 1.5-inch CCAW voice coil and FEM-optimized magnetic structure ensure precise response and excellent thermal stability, even during demanding playback.

Despite its compact footprint, 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 enhanced damping, and the proprietary Airflow Venting Cooling system for continuous heat dissipation.

Optimized to perform at its best in compact sealed enclosures (12–14 L / 0.4–0.5 ft³), it offers deep, controlled bass response even in space-limited setups, making it an ideal choice for refined systems where detail and dynamics must coexist in perfect balance.

Every element reflects the VOCE II philosophy: precision engineering, signature low-frequency response, and unmistakable Italian design.

Important Notes:

Dual 4-Ohm Voice Coil Wiring Flexibility: Features dual 4Ω voice coils allowing series wiring (8Ω final impedance) or parallel wiring (2Ω final impedance). Series configuration suits most factory and aftermarket amplifiers rated for 4-8Ω loads. Parallel configuration (2Ω) extracts higher power from 2-ohm stable amplifiers but generates more heat—ensure adequate ventilation, use thick-gauge wiring (minimum 8 AWG), and verify amplifier is rated 2-ohm stable before parallel wiring.

Sealed Enclosure Optimization Required: Engineered specifically for compact sealed enclosure performance (12–14L / 0.4–0.5 ft³ recommended volume). Sealed alignment delivers fast transient response, tight controlled bass, deep low-frequency extension, and compact installation size. While ported designs are theoretically possible, sealed enclosures maximize the subwoofer's engineering strengths and sound quality characteristics. Incorrect enclosure volume, inadequate bracing, or poor sealing compromises performance and may cause mechanical damage.

Amplifier Power Matching Critical: Match amplifier RMS output to 550W RMS rating at your configured impedance (8Ω series or 2Ω parallel). Underpowering causes clipping distortion damaging voice coils. Overpowering beyond thermal limits causes voice coil failure. Ideal amplifier range: 400-600W RMS. Use proper gain structure, signal processors, and subsonic filtering (25Hz high-pass) protecting against excessive excursion below Fs (36Hz).

Professional Installation Recommended: Premium subwoofer requires precision enclosure construction with proper internal volume, bracing, sealed joints, and acoustic damping material. Amplifier configuration, gain structure, crossover settings, and system integration demand expertise ensuring optimal performance and preventing damage. If unfamiliar with advanced car audio installation, use qualified installer.

Protective Grille Included: Durable black metal mesh grille with mounting screws included providing reliable cone protection without compromising acoustic transparency or visual elegance. Install grille for installations where physical contact possible (trunk installations, behind seats) or omit for maximum aesthetic impact in protected show vehicle installations.

Frequently Asked Questions

Q: What size enclosure do I need for the AV10D4II?

A: The AV10D4II is optimized for compact sealed enclosures between 12-14L (0.4-0.5 ft³). Sealed enclosure design is critical - this subwoofer is specifically engineered for sealed applications and will not perform optimally in ported enclosures. Proper internal volume, quality construction with adequate bracing, and correct mounting ensure the subwoofer achieves its design performance delivering deep, controlled, and fast bass response.

Q: How do I wire the dual 4Ω voice coils?

A: The dual 4Ω voice coils provide two wiring options: Series connection (positive of coil 1 to negative of coil 2) presents 8Ω to the amplifier - suitable for most amplifiers and standard power applications. Parallel connection (positives together, negatives together) presents 2Ω to the amplifier - requires amplifier stable at 2Ω loads and provides higher power transfer. Verify your amplifier's impedance stability and power ratings at your chosen configuration before wiring.

Q: What amplifier power do I need for the AV10D4II?

A: Match amplifier RMS output to the 550W RMS rating at your chosen impedance (8Ω series or 2Ω parallel). For 8Ω series wiring, use amplifier rated 400-600W RMS at 8Ω. For 2Ω parallel wiring, use amplifier rated 400-600W RMS at 2Ω (verify amplifier 2Ω stability first). Underpowering reduces performance potential; overpowering risks thermal or mechanical damage. Quality amplifiers with proper gain structure prevent clipping which causes more damage than power ratings.

Q: Can I use this subwoofer in a ported enclosure?

A: The AV10D4II is specifically engineered and optimized for sealed enclosure applications (12-14L sealed). While technically possible to design a ported enclosure, the Thiele-Small parameters and mechanical design are tuned for sealed operation delivering the intended fast, tight, and accurate bass response characteristic of the Voce II line. For best results and to achieve design performance, use sealed enclosure construction as recommended.

Q: What makes Voce II different from other Audison subwoofers?

A: The Voce II line represents Audison's premium component range featuring advanced engineering including FEM-optimized magnetic circuits, CCAW voice coils, Radial Reinforcement Framework, Airflow Venting Cooling, and meticulous Italian craftsmanship. Voce II components deliver audiophile-grade sonic performance emphasizing accuracy, transient response, control, and musical detail rather than just maximum output. The AV10D4II specifically excels in compact installations where space limitations cannot compromise sound quality expectations, making it ideal for sophisticated car audio systems prioritizing precision and finesse over pure SPL competition.
