It adds low-frequency extension where factory speakers or smaller subwoofers cannot provide sufficient bass depth. Its dual 4-ohm voice coil configuration gives installers useful wiring flexibility when matching the subwoofer to a compatible amplifier.\u003c\/p\u003e\u003cp\u003eBuilt for controlled bass reproduction, the AV 12 D4 II is intended for listeners who want a detailed low end without requiring an oversized enclosure. It is optimized for sealed-box use and is suited to installations where available cargo or cabin space is limited. Audison rates it for 550 watts continuous power handling and 1100 watts peak power handling.\u003c\/p\u003e\u003cp\u003eA 38.6 mm (1.5-inch) CCAW voice coil combines copper-clad aluminum wire construction with a glass-fiber former. The motor structure uses a ferrite magnet and Airflow Venting Cooling technology to help manage heat during sustained operation. This design supports consistent performance when the subwoofer is driven by an appropriately matched amplifier.\u003c\/p\u003e\u003cp\u003eThe polypropylene cone uses an extended-profile dust cap and Radial Reinforcement Framework to improve structural stability during excursion. Audison also uses FEM optimization in the magnetic circuit and dust-cap design to support cone rigidity and damping. The result is a subwoofer engineered for clean, controlled bass across its 25 to 400 Hz rated frequency response.\u003c\/p\u003e\u003cp\u003eThe AV 12 D4 II fits naturally into a VOCE II-based upgrade or a custom active system using a dedicated subwoofer amplifier. Its 4+4-ohm configuration can be wired in series or parallel according to the amplifier's approved impedance range. A protective metal mesh grille is included for installations where the cone may be exposed.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Supports flexible series or parallel wiring with a compatible amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e550W Continuous Handling:\u003c\/strong\u003e Provides substantial power capacity for a dedicated bass channel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.5-Inch CCAW Voice Coil:\u003c\/strong\u003e Helps balance thermal handling with reduced moving mass.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirflow Venting Cooling:\u003c\/strong\u003e Directs airflow through internal channels to manage voice-coil heat.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforced Polypropylene Cone:\u003c\/strong\u003e Uses R.R.F. structure and an extended-profile dust cap for stability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDie-Cast Aluminum Basket:\u003c\/strong\u003e Provides a rigid platform with integrated cable-routing hooks.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe AV 12 D4 II uses a die-cast aluminum chassis, ferrite magnetic assembly, polypropylene cone, nitrile-rubber surround, and glass-fiber voice-coil former. Its basket incorporates a magnet cover and dual cable-routing hooks, while spring-loaded horizontal terminals accept up to 8 AWG cable. A black metal mesh grille and mounting screws are included to protect the driver in exposed installations.\u003c\/p\u003e\u003cp\u003ePlan the enclosure and amplifier together before installation. Audison publishes sealed and reflex enclosure designs, including a 21 L compact sealed alignment with a 284 mm mounting hole; verify mounting depth, clearance, and final internal air volume in the vehicle. Use an amplifier stable at the final impedance created by the selected series or parallel voice-coil wiring, and apply the published crossover guidance as a starting point for system tuning.\u003c\/p\u003e","brand":"Audison","offers":[{"title":"Default Title","offer_id":45614236663878,"sku":"AV 12 D4 II","price":899.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71wFZmN33yL_17a6ea90-65ce-40bf-987f-ada3ad70bf25.jpg?v=1784363441","url":"https:\/\/audiowatt.store\/products\/audison-av-12-d4-ii-12-dual-4-ohm-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
