STX Audio SX692 6x9" 3-Way Coaxial Car Speakers

The STX Audio SX692 Street Series is a pair of 6 x 9 inch coaxial car speakers for replacing worn factory speakers or building a straightforward audio upgrade. Each speaker combines three drivers in one assembly: a woofer, bridge-mounted midrange driver, and bridge-mounted tweeter. This format brings low, midrange, and high-frequency playback to compatible door or rear-deck locations without requiring separate component speakers.

Designed for compatible 4-ohm car audio systems, the SX692 pair can work with many factory or aftermarket head units and properly matched amplification. It is rated for 240 watts RMS per pair, equal to 120 watts RMS per speaker, with 800 watts maximum power handling per pair. A 92 dB sensitivity rating supports efficient everyday listening when the speakers are correctly installed and powered.

The three-way coaxial layout is intended for listeners who want fuller sound from a compact replacement-speaker format. The woofer handles the foundation of the music while the bridge-mounted midrange and tweeter address vocal and upper-frequency detail. Its stated 52 Hz to 20 kHz frequency response covers a broad portion of the audible range.

STX Audio uses a black injection-molded cone and flexible rubber edge surround to support controlled cone movement. A 1.2-inch aluminum voice coil, 20-ounce magnet, and black steel basket provide the speaker's supporting structure. These materials suit an installation where durability and a clean, coordinated appearance are important.

The SX692 set is intended for vehicles with compatible 6 x 9 inch mounting locations, commonly found in rear decks or doors. It includes two matching speakers and two black grilles with gold accents for visible installations. Before purchase, verify mounting opening, depth clearance, mounting-hole pattern, wiring polarity, and whether vehicle-specific brackets or harness adapters are needed.

Key Features

• Three-Way Coaxial Design: Each speaker combines woofer, midrange, and tweeter drivers.
• 6 x 9 Inch Size: Fits compatible rear-deck and door speaker locations.
• 120W RMS Per Speaker: Supports properly matched aftermarket amplification.
• 4-Ohm Impedance: Works with compatible factory or aftermarket audio systems.

• Matching Accent Grilles: Two black grilles with gold accents are included.

Design & Installation

The SX692 uses black injection-molded cones, rubber edge surrounds, 1.2-inch aluminum voice coils, 20-ounce magnets, and black steel baskets. Each speaker uses a bridge-mounted midrange driver and tweeter above the woofer cone. The included black grilles feature gold accents to complement the Street Series look.

Install these speakers only in a location that accepts a compatible 6 x 9 inch speaker footprint and provides adequate mounting depth. Confirm mounting-hole alignment, wiring polarity, and factory connector requirements before beginning installation. Use a compatible 4-ohm head unit or amplifier, and set amplifier gain conservatively to stay within the 120W RMS per-speaker rating.
