Each pair combines a full-size oval woofer with dedicated midrange and tweeter elements in a single speaker assembly. Its 4-ohm load is suited to car audio head units and compatible external amplifiers.\u003c\/p\u003e\u003cp\u003eWith 140 watts RMS handling per pair and 520 watts peak handling per pair, the ST-694 is intended for systems that need more output capability than many original-equipment speakers. The rated 92 dB sensitivity supports useful output from modest-power sources when the system is set up properly. Its 30 Hz to 20 kHz frequency-response rating is designed to cover bass, midrange, and high-frequency content from one coaxial location.\u003c\/p\u003e\u003cp\u003eThe 6x9-inch polypropylene woofer cone provides the primary low- and mid-frequency foundation, while the polyester foam surround supports cone movement. A 2-inch midrange and 1\/2-inch PEI balanced-dome tweeter handle upper-frequency detail within the coaxial assembly. This layout makes the ST-694 a practical choice for listeners seeking a straightforward full-range speaker replacement.\u003c\/p\u003e\u003cp\u003eSoundXtreme specifies an aluminum 1-inch voice coil and an Electric Crystal Motor tweeter magnet. The speakers use spade terminals for conventional speaker-wire connections. Protective grilles are included, providing an option for exposed or custom installations.\u003c\/p\u003e\u003cp\u003eBefore ordering, compare the vehicle's available mounting opening and rear clearance with the ST-694's published cutout and depth measurements. The speakers can be connected to a compatible head unit or amplifier, but clean power and correct polarity are important for proper operation. They can serve as a rear-deck, door, or custom-installation upgrade where the mounting dimensions and clearance are suitable.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Way Coaxial Design:\u003c\/strong\u003e Integrates woofer, midrange, and tweeter elements into each speaker.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6x9-Inch Woofer:\u003c\/strong\u003e Provides an oval cone area for full-range car audio use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e140W RMS Per Pair:\u003c\/strong\u003e Supports sustained playback within the published pair rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Ohm Impedance:\u003c\/strong\u003e Matches many common car audio speaker outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolypropylene Cone:\u003c\/strong\u003e Provides a durable woofer diaphragm material.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePEI Balanced-Dome Tweeter:\u003c\/strong\u003e Handles high-frequency reproduction in the coaxial assembly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe ST-694 uses a polypropylene woofer cone, polyester foam woofer surround, PEI tweeter dome, and aluminum voice coil. Its coaxial layout places the midrange and tweeter components over the woofer, helping consolidate full-range reproduction into a 6x9-inch speaker location. Included grilles can help protect the speaker faces where clearance permits their use.\u003c\/p\u003e\u003cp\u003eVerify the 5-5\/8 x 8-7\/16-inch mounting cutout, 3-3\/16-inch bottom-mount depth, and 7\/16-inch top-mount depth before installation. Connect positive and negative speaker leads to the corresponding spade terminals, and avoid operating the speakers at audible distortion. Disconnect the vehicle battery before electrical work and use mounting hardware suitable for the vehicle's speaker location.\u003c\/p\u003e","brand":"SoundXtreme","offers":[{"title":"Default Title","offer_id":45660878045254,"sku":"ST-694","price":57.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/81-D9aRG7NL.jpg?v=1784447850","url":"https:\/\/audiowatt.store\/products\/soundxtreme-st-694-6x9-4-way-coaxial-car-speakers","provider":"Audio Watt Store","version":"1.0","type":"link"}
