Gravity G3-15D2 15" Dual 2-Ohm Car Subwoofer

The Gravity G3-15D2 is a 15-inch car audio subwoofer made for systems that need dedicated low-frequency output beyond what full-range speakers can reproduce. Its large woofer format is intended for enthusiasts building a bass-focused upgrade in a vehicle with adequate enclosure space. The dual-voice-coil design provides flexibility when planning a compatible amplifier and wiring configuration.

Rated for 1,200 watts RMS and 2,400 watts peak power per subwoofer, the G3-15D2 is designed for substantial continuous power handling when matched with an appropriate amplifier. Its published 30 Hz to 500 Hz frequency-response range covers low bass through upper-bass duties. An 87 dB sensitivity rating is also specified.

This model uses a competition-grade pressed paper cone paired with a high-roll foam surround. That material combination is designed to support controlled cone movement while providing the compliance needed for bass reproduction. The foam surround also forms the visible outer suspension of the woofer assembly.

Gravity specifies an advanced air-flow cooling system for the G3-15D2. Cooling is an important consideration in a high-power subwoofer system because sustained playback can create heat at the voice coils. This design feature is intended to support operation during extended listening sessions.

The G3-15D2 is suited to a custom car-audio installation using a separately selected enclosure and amplifier. Its two 2-ohm voice coils allow the final load to be planned around the amplifier's stable impedance range. Confirm the enclosure dimensions, available mounting space, amplifier capability, and complete wiring plan before installation.

Key Features

• 15-Inch Woofer: Provides a large cone area for dedicated bass reproduction in a custom vehicle audio system.
• 1,200W RMS Rating: Supports amplifier matching based on continuous power handling rather than peak output alone.
• Dual 2-Ohm Voice Coils: Gives installers wiring options when configuring the subwoofer load for a compatible amplifier.
• Pressed Paper Cone: Uses the specified competition-grade cone material for the moving diaphragm.
• High-Roll Foam Surround: Supports cone travel and forms a durable outer suspension around the cone.
• Air-Flow Cooling System: Is specified to help manage heat during extended high-power playback.

Design & Installation

The G3-15D2 combines a competition-grade pressed paper cone with a high-roll foam surround in a 15-inch subwoofer format. Its published construction also includes an advanced air-flow cooling system. These elements are intended for a dedicated bass driver rather than a full-range speaker application.

Use the G3-15D2 in a properly designed enclosure that fits both the subwoofer and the vehicle's available space. Select an amplifier with power delivery and minimum-impedance capability appropriate for the final dual-voice-coil wiring arrangement. Mounting depth, cutout diameter, enclosure volume, terminal type, and included hardware were not confirmed in the available product specifications, so verify these details before purchase or fabrication.
