Gravity GR-1686H 6.5" 2-Way Coaxial Car Speakers

The Gravity GR-1686H is a pair of 6.5-inch 2-way coaxial car speakers designed to replace worn or basic factory door speakers. It provides a straightforward upgrade path for vehicles that accept 6.5-inch speakers. Its full-range coaxial format combines the woofer and tweeter into each speaker assembly for simplified installation.

With 230 watts maximum power handling per pair, the GR-1686H is intended for everyday in-car listening with either a compatible factory radio or an appropriately matched aftermarket system. The 4-ohm impedance supports common automotive speaker applications. Its 90 dB sensitivity rating is specified for efficient output from modest power sources.

The speaker uses a Nomex and silk cone woofer construction to support controlled midrange and low-frequency reproduction. A soft-dome tweeter is integrated into the coaxial design to reproduce upper-frequency detail. The specified 60 Hz to 20 kHz frequency response covers the core range of music, speech, and general entertainment playback.

A 15-ounce magnet and 25 mm voice coil are specified for the GR-1686H. These components form the motor and moving-coil structure that drives the speaker cone. The design is suited to replacement and entry-level custom car-audio installations where space is limited.

The GR-1686H is a practical choice for cars, trucks, and SUVs with compatible 6.5-inch speaker locations. It can be used as a direct speaker replacement or as part of a broader system upgrade with a compatible head unit or amplifier. Confirm vehicle mounting dimensions, connector fitment, and available mounting depth before installation.

Key Features

• 6.5-Inch Coaxial Format: Combines woofer and tweeter functions in each speaker for a compact full-range replacement solution.
• 2-Way Speaker Design: Separates low/midrange and high-frequency reproduction through dedicated driver elements.
• 230W Maximum Handling: Provides a stated maximum power capacity of 230 watts per pair.
• Nomex And Silk Cone: Uses the specified cone materials for responsive everyday music playback.
• 90 dB Sensitivity: Supports useful output with compatible factory radios and moderate aftermarket power.
• 4-Ohm Impedance: Matches the common nominal impedance used by many automotive audio systems.

Design & Installation

The GR-1686H uses a 15-ounce magnet and 25 mm voice coil in a compact 6.5-inch speaker platform. Its coaxial layout places the tweeter within the woofer assembly, helping it fit applications where separate component-speaker mounting locations are not available. Spade-style speaker terminals are specified for connection.

Verify that the vehicle accepts 6.5-inch speakers and confirm mounting depth, cutout diameter, screw locations, and door-panel clearance before purchasing. Use vehicle-specific adapter brackets or wiring harnesses when required, and match the speakers to a compatible 4-ohm radio or amplifier output. Product listings identify a pair of speakers with speaker wire, screws, and a user manual; contents should be checked upon receipt.
