Its integrated woofer-and-tweeter design replaces a compatible full-range speaker position with a more capable two-way arrangement. These speakers are supplied without grilles for installations that retain the vehicle’s existing speaker covers or use a factory-style mounting location.\u003c\/p\u003e\u003cp\u003eWith 50 watts RMS power handling, 400 watts peak power handling, and 89 dB sensitivity, the STAGE3 48F is suited to aftermarket head units as well as appropriately matched external amplification. The true 4-ohm nominal load is designed to work efficiently with compatible car-audio electronics. Its 80 Hz to 20 kHz frequency response covers the main midrange and high-frequency range expected from a compact coaxial speaker.\u003c\/p\u003e\u003cp\u003eA PEI balanced dome tweeter handles high frequencies from the center of each speaker. This coaxial layout keeps the system simple by combining the woofer and tweeter into one assembly. It is a practical option for listeners seeking clearer high-frequency detail from a compact 4-inch replacement speaker format.\u003c\/p\u003e\u003cp\u003eThe woofer uses JBL's Plus One cone architecture, which increases usable cone area relative to conventional designs in its class. Its laser-etched cone is reinforced with 10% glass fiber and finished with a forged-carbon-fiber-inspired visual effect. Together, these design elements support the speaker’s low-frequency output within the limits of its 4-inch size.\u003c\/p\u003e\u003cp\u003eThe STAGE3 48F can serve as a focused replacement for worn or limited factory speakers in compatible dash, door, or rear locations. It includes basic installation hardware, foam gaskets, and spade clips to support mounting and wiring. Confirm the vehicle’s mounting depth, cutout size, factory connector, and clearance before installation, especially where the speaker is mounted behind a trim panel.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Inch Coaxial Design:\u003c\/strong\u003e Combines woofer and tweeter functions in each compact speaker assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e50W RMS Power Handling:\u003c\/strong\u003e Supports matching with compatible head units or amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlus One Woofer Cone:\u003c\/strong\u003e Provides increased cone area for a compact speaker format.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePEI Balanced Dome Tweeter:\u003c\/strong\u003e Reproduces high frequencies through an integrated coaxial tweeter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrue 4-Ohm Load:\u003c\/strong\u003e Matches common 4-ohm car-audio speaker system requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory-Style Package:\u003c\/strong\u003e Supplied without grilles for compatible OEM-style locations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe STAGE3 48F uses a laser-etched woofer cone reinforced with 10% glass fiber, a PEI balanced dome tweeter, and a rubber surround. JBL also specifies post-consumer recycled plastic materials, PVC-free wiring, and soy-ink packaging for the Stage3 Gen2 family.

Use the supplied foam gaskets and mounting hardware where appropriate, and connect the included spade clips with correct polarity. Vehicle-specific adapter brackets or wiring harnesses may still be required depending on the factory location and connector.\u003c\/p\u003e","brand":"JBL","offers":[{"title":"Default Title","offer_id":45632139427910,"sku":"JBLSPKS348F","price":76.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61T1q2HuQ6L.jpg?v=1784397088","url":"https:\/\/audiowatt.store\/products\/jbl-stage3-48f-4-2-way-coaxial-speakers","provider":"Audio Watt Store","version":"1.0","type":"link"}
