Cerwin-Vega H15DV2 15" Dual 2-Ohm Car Subwoofer

The Cerwin-Vega H15DV2 is a 15-inch HED Series car audio subwoofer designed to add low-frequency output to a custom vehicle sound system. Its dual 2-ohm voice coils provide wiring flexibility for matching the subwoofer to a compatible mono amplifier. It is a passive subwoofer, so it requires an external amplifier and an enclosure.

This model is suited to listeners building a bass-focused system who have room for a full-size 15-inch driver and enclosure. Its 750-watt RMS power rating supports use in systems designed for substantial continuous bass output. The 25 Hz free-air resonance and 11 mm Xmax support low-frequency extension when used with an appropriate enclosure.

The H15DV2 uses a 4-inch voice coil, ferrite motor structure, and dual voice-coil layout. These elements are intended to support power handling and give installers impedance options. With both 2-ohm coils connected, it can be wired for either a 1-ohm parallel load or a 4-ohm series load.

A polypropylene cone and treated foam surround form the moving assembly, while the stamped-steel basket provides the mounting structure. The driver has a sensitivity rating of 86 dB at 1 watt/1 meter. Its published Thiele/Small parameters can help an experienced installer or enclosure builder plan a system around the subwoofer.

The H15DV2 can be used in either sealed or ported enclosures, allowing the system to be tailored to installation space and listening preferences. A sealed design is commonly selected for a more compact enclosure approach, while a ported design is commonly used when enclosure volume and tuning are planned for greater low-frequency output. Confirm amplifier stability, enclosure dimensions, and vehicle clearance before installation.

Key Features

• 15-Inch HED Subwoofer: Provides a large cone area for a bass-focused car audio system.
• Dual 2-Ohm Voice Coils: Supports 1-ohm parallel or 4-ohm series wiring configurations.
• 750W RMS Power Handling: Matches with an amplifier sized for 750 watts RMS.
• 4-Inch Voice Coil: Supports the driver's published continuous power capability.
• Ferrite Motor: Provides the magnetic motor structure for the woofer.
• Sealed Or Ported Compatibility: Allows enclosure selection based on system goals and available space.

Design & Installation

The H15DV2 combines a polypropylene cone, treated foam surround, ferrite magnet, and stamped-steel basket. Its published overall diameter is 15.63 inches, and its overall height is 8.39 inches. The 4-inch voice coil and 11 mm maximum linear excursion specification are part of its bass-driver design.

Allow for a 13.94-inch cutout and at least 7.66 inches of mounting depth, plus clearance for terminals and enclosure construction. Connect both voice coils and select series or parallel wiring only when the connected amplifier is stable at the resulting load. Use the published parameters when designing a sealed or ported enclosure, and secure the driver with appropriate mounting hardware.
