Gravity GR-5786H 5x7/6x8" 2-Way Coaxial Speakers

The Gravity GR-5786H is a pair of 5x7 / 6x8-inch coaxial car speakers designed as a replacement option for compatible factory speaker locations. It is intended for drivers who want to refresh worn factory speakers or add clearer full-range sound without moving to a separate-component speaker system. Its 4-ohm design supports use with many factory and aftermarket car audio systems.

Each GR-5786H speaker uses a 2-way coaxial layout, combining the main woofer and high-frequency driver in one assembly. This arrangement is well suited to door, rear-deck, or other factory-style locations where space is limited. The design is intended to reproduce midrange detail and treble while retaining the practicality of a full-range replacement speaker.

Silver alpha cellulose cones form the main radiating surface, while moisture-resistant rubber surrounds support cone movement and help the speakers hold up in changing vehicle conditions. The listed frequency response is 70 Hz to 20 kHz, covering much of the audible midrange and treble range. For deeper bass, these speakers can be used as part of a system that also includes a dedicated subwoofer.

An anti-resonant stamped-steel basket provides the speaker structure and is intended to reduce unwanted vibration. The speakers use 25 mm voice coils and a 6.5-ounce magnet specification. A neo mylar soft-dome tweeter is incorporated into the coaxial assembly for high-frequency reproduction.

The GR-5786H is rated at 230 watts maximum power handling per pair, or 115 watts maximum per speaker. Spade terminals simplify conventional speaker-wire connections during installation. Before purchase, confirm the vehicle's factory opening, mounting depth, screw pattern, and any adapter requirements, since fitment can vary by vehicle even when the nominal speaker size matches.

• Rubber Surround: Offers moisture resistance and supports cone movement.
• Spade Terminals: Enable straightforward conventional speaker-wire connections.

Design & Installation

The GR-5786H uses silver alpha cellulose cones, moisture-resistant rubber surrounds, and stamped-steel baskets. Its 25 mm voice coils, 6.5-ounce magnets, and integrated neo mylar soft-dome tweeters are housed in a full-range coaxial speaker format. This construction keeps the woofer and tweeter together for a compact replacement-speaker design.

Use the GR-5786H as a pair in vehicle locations designed for 5x7-inch or 6x8-inch speakers, after verifying physical fitment for the specific vehicle. Connect the speaker leads to the spade terminals while observing proper polarity, and securely mount each speaker using vehicle-appropriate hardware. An amplifier is not required by the published product description, but source power should be matched carefully to the speaker's stated ratings.
