It handles 400 watts RMS and 800 watts peak, making it suitable for an amplifier-matched bass upgrade. Its selectable impedance design helps simplify system planning when amplifier requirements or future expansion needs may change.\u003c\/p\u003e\u003cp\u003eThis subwoofer uses Memphis FLEX Triple Selectable Impedance technology to present a 1-ohm, 2-ohm, or 4-ohm load through a repositionable jumper plug. That flexibility lets an installer match the woofer to a compatible mono amplifier without replacing the subwoofer. The same 400-watt RMS and 800-watt peak handling applies across the selectable impedance settings.\u003c\/p\u003e\u003cp\u003eThe PRX12FT is intended for listeners who want substantial bass from a single 12-inch driver while retaining options for system changes later. Its sensitivity varies slightly by selected load, rated at 85.6 dB at 1 ohm, 85.5 dB at 2 ohms, and 86 dB at 4 ohms. A properly selected enclosure and amplifier are important for getting the intended performance from the subwoofer.\u003c\/p\u003e\u003cp\u003eMemphis uses Direct Voice Coil Cooling technology to help manage heat at the voice coil during operation. The design also incorporates a reinforced spider, improved suspension and coil design, and woven tinsel leads. These construction details support controlled cone movement and dependable signal transfer in a high-output car audio installation.\u003c\/p\u003e\u003cp\u003eA black-on-black polypropylene cone and stitched butyl rubber surround give the PRX12FT a durable, understated appearance. With a 5.5-inch mounting depth and 11-inch cutout requirement, it can be used in many custom or prefab 12-inch enclosures with sufficient clearance. It supports sealed and vented enclosure approaches, allowing installers to prioritize compactness and control or greater output efficiency.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFLEX Triple Impedance:\u003c\/strong\u003e Select 1-ohm, 2-ohm, or 4-ohm operation with the included jumper.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e400W RMS Handling:\u003c\/strong\u003e Matches with a properly configured amplifier delivering up to 400 watts RMS.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Voice Coil Cooling:\u003c\/strong\u003e Helps manage voice-coil heat during sustained playback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolypropylene Cone:\u003c\/strong\u003e Provides a durable cone material for automotive bass applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStitched Butyl Surround:\u003c\/strong\u003e Supports cone travel with a durable rubber surround.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Inch Voice Coil:\u003c\/strong\u003e Uses a high-temperature TIL voice coil former.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe PRX12FT combines a black polypropylene cone, stitched butyl rubber surround, reinforced spider, woven tinsel leads, and a high-temperature TIL voice coil former. Its 59-ounce magnet structure is fitted with a removable rubber magnet boot, while the steel basket provides a rigid mounting platform. Memphis also specifies improved suspension and coil design to support the driver’s bass-focused role.\u003c\/p\u003e\u003cp\u003ePlan for an 11-inch cutout and at least 5.5 inches of mounting depth, plus sufficient rear clearance inside the enclosure. Select the impedance by moving the included FLEX Plug Jumper to the 1-ohm, 2-ohm, or 4-ohm terminal before connecting a compatible amplifier; the factory setting is 4 ohms. Memphis enclosure recommendations include sealed volumes from 1.0 to 1.5 cubic feet and vented alignments from 1.8 to 2.65 cubic feet, depending on the preferred bass character.\u003c\/p\u003e","brand":"Memphis","offers":[{"title":"Default Title","offer_id":45633195573318,"sku":"PRX12FT","price":179.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71t50lZNwnL.jpg?v=1784413243","url":"https:\/\/audiowatt.store\/products\/memphis-prx12ft-12-selectable-impedance-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
