Gravity SGR574 5x7/6x8 4-Way Coaxial Car Speakers

The Gravity SGR574 is a pair of 4-way full-range car speakers designed for vehicles using 5x7-inch or 6x8-inch speaker locations. They provide a practical replacement option for worn or basic factory speakers while retaining a conventional 4-ohm load. The coaxial layout places multiple drivers in each speaker assembly to reproduce a broad portion of the audible range from one mounting location.

With a stated frequency response of 105Hz to 20kHz, the SGR574 is intended for everyday music listening, spoken-word playback, and general car-audio upgrades. Its 85 dB sensitivity rating and 4-ohm impedance make it suitable for use with compatible factory radios or aftermarket amplification. The 300-watt peak-power specification describes short-duration power handling rather than a continuous RMS rating.

Each speaker uses a silver alpha cellulose cone and a moisture-resistant rubber surround. This combination is intended to support regular automotive use where temperature and humidity can vary. A stamped steel basket provides the structural frame for the speaker assembly.

The 4-way design includes midrange and high-frequency elements in addition to the main cone driver. Gravity specifies 28 mm PEI midrange and tweeter components, along with a neo-mylar soft-dome tweeter designation. This arrangement is intended to distribute different portions of the audio range across multiple driver elements.

The SGR574 is suited to a straightforward front- or rear-speaker upgrade where a vehicle accepts 5x7-inch or 6x8-inch speakers. Spade terminals support conventional speaker-wire connections, though vehicle-specific harness adapters may be useful depending on the factory wiring. For systems needing stronger low-frequency output below the speaker's rated range, these speakers can be paired with a properly configured subwoofer system.

Key Features

• 5x7/6x8 Fitment: Designed for common oval factory speaker locations.
• 4-Way Coaxial Design: Combines multiple driver elements in each speaker.
• 300W Peak Handling: Supports stated short-duration peak power capability.
• 4-Ohm Impedance: Works with compatible car-audio speaker outputs.
• Silver Alpha Cellulose Cone: Provides the main cone-driver construction.
• Spade Terminals: Allow conventional speaker-wire connections during installation.

Design & Installation

The SGR574 uses silver alpha cellulose cones, moisture-resistant rubber surrounds, and an anti-resonant stamped steel basket. Its listed 6.5-ounce magnet and 25 mm voice coil are part of the speaker motor and voice-coil assembly. The speaker also incorporates 28 mm PEI midrange and tweeter components.

Confirm the vehicle's factory speaker opening, mounting depth, mounting-hole pattern, and connector style before ordering, as these measurements are not specified in the available product information. Connect each speaker to a compatible 4-ohm channel and observe amplifier or radio power limits to avoid distortion. Factory harness adapters or mounting adapters may be needed for certain vehicles and are not confirmed as included.
