Gravity GW15D2 15" Dual 2-Ohm Car Subwoofer

The Gravity GW15D2 is a 15-inch car-audio subwoofer designed for systems that need dedicated low-frequency output beyond what full-range speakers can provide. Its large driver format is suited to custom trunk, cargo-area, or other enclosure-based installations where space is available. The GW15D2 is sold as a passive subwoofer, so it requires an external amplifier and an appropriate enclosure.

Built around dual 2-ohm voice coils, the GW15D2 gives installers flexibility when planning the final impedance presented to a compatible amplifier. This makes it a practical choice for custom single-subwoofer systems as well as multi-subwoofer builds. Correct wiring and amplifier matching are important for dependable operation.

Gravity lists 3500 watts peak power handling and 1750 watts RMS power handling for this model. Its specified frequency response is 30 Hz to 500 Hz, covering the low-frequency range typically assigned to a subwoofer. With an 85 dB sensitivity rating, it is intended for use with a properly selected external car-audio amplifier.

The driver uses a competition-grade pressed paper cone and a high-roll foam surround. This combination is designed to support cone movement while maintaining the low-frequency character expected from a large-diameter subwoofer. An advanced airflow cooling system is also specified to help manage heat during extended use.

The GW15D2 can be used as the bass foundation of a custom car-audio upgrade, paired with an amplifier, enclosure, wiring, and a source unit or signal processor as needed. Its 15-inch size favors installations with sufficient enclosure and vehicle space. Confirm mounting clearance, enclosure requirements, amplifier stability, and wiring configuration before purchase or installation.

Key Features

• 15-Inch Subwoofer: Large-diameter driver intended for dedicated car-audio bass reproduction.
• Dual 2-Ohm Voice Coils: Provides wiring flexibility for compatible amplifier configurations.
• 1750W RMS Handling: Supports continuous-power system matching when properly installed.

• Airflow Cooling System: Helps manage heat during sustained high-power operation.

Design & Installation

The GW15D2 combines a pressed paper cone with a high-roll foam surround and an advanced airflow cooling design. These components are intended for the demands of an enclosure-based car-audio subwoofer installation. The driver is specified as a 15-inch model with dual 2-ohm voice coils and a 30 Hz to 500 Hz frequency-response range.

Plan this subwoofer as part of a complete system: it needs a compatible external amplifier, properly sized enclosure, speaker wiring, and adequate vehicle mounting space. Wire both voice coils according to the amplifier's supported impedance range, and use amplifier gain and low-pass crossover settings appropriate for a subwoofer. The listed package dimensions are 17.3 x 17.1 x 11.7 inches, but verify the actual driver clearance and enclosure dimensions before installation.
