Its SSI selectable-impedance switch lets the installer configure the woofer for either a 2-ohm or 4-ohm load. This makes it suitable for a new custom bass system or for upgrading an existing amplifier and enclosure setup.\u003c\/p\u003e\u003cp\u003eWith 500 watts RMS power handling and a 25Hz–175Hz frequency response, the Stadium 122SSI is intended to reproduce deep bass while covering the upper-bass range needed for a well-integrated subwoofer system. Its 92dB sensitivity rating is measured at 2.83V. The 12-inch format suits listeners who have room for a properly sized enclosure and want bass support beyond factory speakers.\u003c\/p\u003e\u003cp\u003eJBL's SSI technology uses a dual-impedance switch rather than requiring a different subwoofer model for each target load. The switch can be set to 2 or 4 ohms to accommodate different amplifier and multi-subwoofer configurations. Turn the subwoofer amplifier off before changing the SSI switch position.\u003c\/p\u003e\u003cp\u003eAn aero-cooled voice-coil design channels air through the motor as the cone moves, helping expose the voice coil to airflow. JBL pairs this arrangement with a 2-inch voice coil to balance thermal power handling and moving mass. The result is an engineered driver intended for sustained use in a car-audio enclosure.\u003c\/p\u003e\u003cp\u003eThe Stadium 122SSI is a passive component subwoofer, so it requires an external amplifier and enclosure. JBL specifies a 1.3-cubic-foot sealed enclosure or a 2.5-cubic-foot vented enclosure as reference designs. Its 2- or 4-ohm flexibility can simplify amplifier selection now and system expansion later.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSSI Selectable Impedance:\u003c\/strong\u003e Choose a 2-ohm or 4-ohm load to suit the amplifier and system design.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e500W RMS Handling:\u003c\/strong\u003e Supports amplifier matching around its continuous 500-watt power rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAero-Cooled Voice Coil:\u003c\/strong\u003e Airflow through the motor helps manage voice-coil heat during operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Inch Voice Coil:\u003c\/strong\u003e Uses an oversized 50mm voice coil for thermal capacity and controlled mass.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e92dB Sensitivity:\u003c\/strong\u003e Delivers rated sensitivity of 92dB at 2.83V.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Push Terminals:\u003c\/strong\u003e Accommodate up to 8 AWG speaker wire for the subwoofer connection.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe Stadium 122SSI combines a 12-inch driver platform with an aero-cooled motor and 2-inch voice coil. Its integrated terminals support up to 8 AWG wire, while the selectable-impedance switch is built into the subwoofer for system configuration. JBL lists a 7-inch mounting depth and an 11-1\/5-inch cutout diameter.\u003c\/p\u003e\u003cp\u003eInstall the subwoofer in a compatible sealed or vented enclosure and pair it with an external amplifier appropriate for the selected 2-ohm or 4-ohm setting. JBL's reference sealed enclosure volume is 1.3 cubic feet; its vented reference is 2.5 cubic feet with a 4-inch-diameter, 10-inch-long port tuned to 35Hz. Use 14–8 AWG speaker wire based on wire-run length, with heavier wire preferred for runs longer than 6 feet.\u003c\/p\u003e","brand":"JBL","offers":[{"title":"Default Title","offer_id":45632346718278,"sku":"JBLSUBSD122SSIAM","price":209.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61tuhnhlitL.jpg?v=1784399458","url":"https:\/\/audiowatt.store\/products\/jbl-stadium-122ssi-12-car-audio-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
