Gravity SGR464 4x6" 4-Way Coaxial Speakers

The Gravity SGR464 is a pair of 4x6-inch, 4-way coaxial car speakers intended to replace factory speakers in vehicles that use this compact oval size. It provides a full-range speaker solution for systems with worn, damaged, or basic OEM door speakers. Its 4-ohm impedance supports use with many factory and aftermarket car-audio speaker outputs.

This speaker is suited to drivers looking to refresh sound in factory locations without moving to a separate-component speaker system. The 4-way coaxial layout places multiple drivers within each speaker assembly, allowing one location to reproduce a broad portion of the audible range. It is a practical choice for front or rear locations when the vehicle accepts a 4x6-inch speaker.

Gravity rates the SGR464 at up to 180 watts peak power, with a published sensitivity of 90 dB. Its stated frequency response is 120 Hz to 20 kHz, covering midrange and high-frequency content for everyday listening. As with other compact full-range speakers, deeper bass performance depends on the vehicle installation and the rest of the audio system.

An alpha cellulose cone forms the main sound-producing surface, while a moisture-resistant rubber surround supports the cone's movement. The speaker also uses an anti-resonant stamped steel basket designed to provide a stable mounting structure. Together, these materials focus on dependable use in typical automotive environments.

The SGR464 can be used with a factory radio or an aftermarket head unit that supports 4-ohm speakers. It may also be part of a larger upgrade that includes an external amplifier and dedicated low-frequency reinforcement. Verify the vehicle's factory speaker opening, mounting depth, mounting-hole pattern, and available clearance before purchase.

Design & Installation

The SGR464 uses alpha cellulose cones, moisture-resistant rubber surrounds, and anti-resonant stamped steel baskets. These construction details support the speaker assembly in automotive door, dash, or rear-deck environments where compact fitment and vibration resistance matter. The published magnet size is 2-3/4 inches, and the published mounting depth is 2-1/4 inches.

Use the spade speaker terminals to connect positive and negative speaker wiring, observing correct polarity at both speakers. Before installation, compare the vehicle's opening, depth, terminal clearance, and mounting-hole pattern with the speaker dimensions; adapter brackets or wiring adapters may be required depending on the vehicle. The package includes two SGR464 speakers and a warranty card.
