STX Audio SX652 6.5" 3-Way Coaxial Car Speakers

The STX Audio SX652 is a pair of 6.5-inch 3-way coaxial car speakers made for refreshing compatible factory door or rear-deck speaker locations. Each speaker combines a woofer, bridge-mounted midrange driver, and bridge-mounted tweeter in one compact assembly. This design gives an existing vehicle audio system a more complete replacement speaker solution without requiring separate component speakers.

The three-driver layout separates low-frequency, vocal, and high-frequency duties within each speaker. The woofer handles the foundation of the music, while the bridge-mounted midrange and tweeter support clearer vocals, instruments, and upper-frequency detail. It is a practical option for listeners replacing worn factory speakers or building a straightforward aftermarket upgrade.

Each SX652 speaker is rated for 80 watts RMS, with a 160-watt RMS rating for the pair. The speakers are also rated for 650 watts maximum system power and use a 4-ohm nominal impedance. Their 90 dB sensitivity and 68 Hz to 20 kHz frequency response support use with compatible factory radios, aftermarket receivers, or properly matched amplification.

A black injection-molded woofer cone and rubber edge surround are used to support controlled cone movement and midbass response. The motor assembly includes a 1-inch aluminum voice coil and a 15-ounce magnet. A black steel basket provides the structural mounting foundation for the speaker assembly.

The SX652 is designed for common 6.5-inch vehicle speaker positions where fitment permits. It can be used in front doors, rear doors, or rear-deck locations after verifying the vehicle's opening, mounting depth, mounting-hole pattern, and wiring needs. The package includes a matched pair of speakers with gold-accent grilles for installations where visible speaker protection is needed.

Design & Installation

The SX652 uses black injection-molded woofer cones, rubber edge surrounds, black steel baskets, 1-inch aluminum voice coils, and 15-ounce magnets. Its coaxial construction places the woofer, bridge-mounted midrange driver, and bridge-mounted tweeter together in each speaker. The included grilles feature gold accents for a visible finishing detail.

Confirm the vehicle's speaker opening, available mounting depth, mounting-hole pattern, and connector requirements before installation. Observe correct speaker polarity when connecting the pair, and use compatible 4-ohm speaker outputs or amplifier channels. These speakers are suited to compatible front-door, rear-door, and rear-deck replacement applications.
