It combines one 12-inch subwoofer with a compact, slim-profile enclosure for vehicles where cargo-space flexibility matters. This is a practical option for listeners upgrading a factory or aftermarket audio system with dedicated bass reinforcement.\u003c\/p\u003e\u003cp\u003eThe enclosure is built around a 2-ohm 12-inch woofer rated for 250 watts RMS power handling. Its specified 34Hz-200Hz frequency response supports bass duties across a broad low-frequency range. With 91dB sensitivity measured at 2.83V\/1m, it is designed to work efficiently with an appropriately matched external amplifier.\u003c\/p\u003e\u003cp\u003eA sealed enclosure design helps keep the installation straightforward while providing a controlled bass foundation for music playback. The Stage 1200S is factory loaded and tuned, eliminating the need to select a separate box or install a loose subwoofer into an enclosure. It is suited to systems that need a complete bass enclosure rather than a component-only subwoofer.\u003c\/p\u003e\u003cp\u003eThe included Stage 122 subwoofer uses a polypropylene cone, rubber surround, and 2-inch voice coil. These components are paired with a 5\/8-inch MDF enclosure covered in black carpet. JBL also states that its car speakers undergo environmental and full-power reliability testing as part of product development.\u003c\/p\u003e\u003cp\u003eBecause this is a passive loaded enclosure, it should be connected to a compatible external subwoofer amplifier and installed securely in the vehicle. Its 2-ohm nominal impedance should be matched to an amplifier that is rated to operate at 2 ohms. The compact enclosure format makes it a sensible addition to a system with an aftermarket radio, factory radio integration, or an existing amplifier upgrade plan.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoaded 12-Inch Enclosure:\u003c\/strong\u003e Includes one preinstalled JBL Stage 122 subwoofer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed Cabinet Design:\u003c\/strong\u003e Provides a ready-to-install bass enclosure format.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e250W RMS Handling:\u003c\/strong\u003e Supports properly matched external amplifier power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Impedance:\u003c\/strong\u003e Designed for compatible 2-ohm-stable subwoofer amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e91dB Sensitivity:\u003c\/strong\u003e Helps convert amplifier power into usable output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlim MDF Construction:\u003c\/strong\u003e Fits more easily than many conventional enclosures.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe Stage 1200S uses a 5\/8-inch MDF enclosure with a black carpet covering and a sealed cabinet configuration. Its loaded 12-inch driver has a polypropylene cone, rubber surround, and 2-inch voice coil. The enclosure measures 17.25 inches wide by 14.5 inches high, with 11.5-inch and 7.75-inch depth measurements.\u003c\/p\u003e\u003cp\u003eInstall the enclosure in a secure location with sufficient clearance for its dimensions and wire routing. It requires an external amplifier capable of driving a 2-ohm load; set amplifier gain and crossover controls appropriately for the system rather than using gain as a volume control. The package includes the enclosure, an owner's manual, and two JBL brand stickers, but no amplifier or amplifier wiring kit is listed.\u003c\/p\u003e","brand":"JBL","offers":[{"title":"Default Title","offer_id":45632357531718,"sku":"JBLSUBST1200SAM","price":288.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61yPpNAT9gL.jpg?v=1784399544","url":"https:\/\/audiowatt.store\/products\/jbl-jblsubst1200sam-12-sealed-car-subwoofer-enclosure","provider":"Audio Watt Store","version":"1.0","type":"link"}
