Its low-profile under-seat format is intended for cars, trucks, and SUVs where available cargo space is limited. The integrated design combines the subwoofer enclosure and amplification in one wired unit.\u003c\/p\u003e\u003cp\u003eThis model is a practical upgrade for listeners who want more bass presence from a factory or aftermarket speaker system. It is intended to supplement full-range speakers rather than replace them. Its compact enclosure makes it especially suited to installations where a conventional subwoofer box would be impractical.\u003c\/p\u003e\u003cp\u003eThe GRWF10 uses a 10-inch driver in an active, enclosed powered-subwoofer configuration. Published product data identifies a 2-ohm subwoofer load, a 20 Hz to 150 Hz frequency-response range, and a signal-to-noise ratio above 90 dB. A built-in low-pass filter helps limit the unit to the bass range it is designed to reproduce.\u003c\/p\u003e\u003cp\u003eSystem-tuning controls include adjustable bass boost and phase-shift adjustment. The bass boost can increase low-frequency emphasis, while phase adjustment can help the subwoofer blend more smoothly with the vehicle's main speakers. A fixed 20 Hz subsonic filter is also listed in published technical data.\u003c\/p\u003e\u003cp\u003eThe GRWF10 supports wired signal connections and is listed with high-level input capability for integration with systems that use speaker-level outputs. Its automatic power on\/off function is intended for high-level connections, reducing the need for a separate turn-on arrangement in compatible installations. For a complete upgrade, it should be professionally wired to the vehicle's electrical system and secured in a location with adequate clearance and ventilation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-Inch Powered Design:\u003c\/strong\u003e Combines a 10-inch subwoofer and built-in amplifier in one enclosure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnder-Seat Profile:\u003c\/strong\u003e Fits applications where trunk-mounted bass systems are not preferred.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Level Auto Turn-On:\u003c\/strong\u003e Supports automatic activation when using high-level signal connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Low-Pass Filter:\u003c\/strong\u003e Lets the bass frequency range be tailored to the system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Bass Boost:\u003c\/strong\u003e Provides adjustable low-frequency emphasis for personal tuning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase Shift Control:\u003c\/strong\u003e Helps align bass output with the rest of the vehicle audio system.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe GRWF10 is listed as an active enclosed subwoofer with an aluminum housing and a rectangular, low-profile form factor. Its compact 15 x 11.4 x 3-inch unit dimensions are designed for under-seat or other space-conscious vehicle mounting locations. A bi-color power-status LED provides a visible operating indication.\u003c\/p\u003e\u003cp\u003eBefore purchase, measure the intended mounting area for clearance around the 15 x 11.4 x 3-inch enclosure and allow room for wiring and ventilation. Installation requires a wired vehicle-audio connection and power wiring; high-level input capability can help it integrate with factory systems that do not provide dedicated RCA preamp outputs. Secure the enclosure firmly rather than leaving it loose beneath a seat, and set gain, low-pass filter, bass boost, and phase controls after installation.\u003c\/p\u003e","brand":"Gravity","offers":[{"title":"Default Title","offer_id":45629043376198,"sku":"GRWF10","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71HaZ1-NX8L.jpg?v=1784376420","url":"https:\/\/audiowatt.store\/products\/gravity-grwf10-10-powered-under-seat-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
