It is intended for vehicle owners who want a more flexible front-stage upgrade than a coaxial speaker can provide. The set includes external in-line crossovers to route appropriate frequencies to the woofer and tweeter.\u003c\/p\u003e\u003cp\u003eEach side is rated for 50 watts RMS and 150 watts peak, with a 3-ohm nominal impedance. The system has a 91 dB sensitivity rating measured at 2.83V\/1m and a stated frequency response of 75 Hz to 20 kHz. These specifications make it suitable for use with a compatible factory or aftermarket radio, or with a properly matched external amplifier.\u003c\/p\u003e\u003cp\u003eThe 5.25-inch woofer uses a polypropylene cone with Infinity Plus One cone architecture and a rubber surround. The design increases usable cone area relative to conventional cones of the same class. Its compact mounting format can be useful where a larger speaker will not fit.\u003c\/p\u003e\u003cp\u003eSeparate 3\/4-inch silk-dome tweeters use an edge-driven design to handle upper-frequency detail. The supplied crossovers use a 5 kHz crossover point with a 12 dB-per-octave slope. With the tweeters mounted higher in a door, dash, sail panel, or factory location where appropriate, the system can support more focused high-frequency placement than a single-point speaker arrangement.\u003c\/p\u003e\u003cp\u003eA vented basket frame is designed to help move heat away from the woofer motor structure during operation. The set is finished in black and includes hardware and multiple tweeter-mounting pieces for installation flexibility. It is a practical choice for a vehicle-specific 5.25-inch component upgrade when mounting depth, cutout size, and electrical compatibility have been verified.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e5.25-Inch Component System:\u003c\/strong\u003e Separate woofers and tweeters support flexible speaker placement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlus One Cone Architecture:\u003c\/strong\u003e Provides increased cone area for its class.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSilk-Dome Tweeters:\u003c\/strong\u003e Handles high frequencies with an edge-driven design.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-Ohm Nominal Impedance:\u003c\/strong\u003e Designed for compatible factory or aftermarket power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal In-Line Crossovers:\u003c\/strong\u003e Directs frequencies between woofers and tweeters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVented Basket Frame:\u003c\/strong\u003e Helps manage heat around the woofer motor.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe Primus 503CF combines polypropylene woofer cones, rubber surrounds, silk-dome tweeters, and rigid vented woofer baskets. The woofer mounting depth is listed at 1.81 inches, while the top-mount cutout requirement is listed at approximately 4.5 inches. No speaker grilles are included with this component system.\u003c\/p\u003e\u003cp\u003eConfirm the vehicle's factory opening, mounting depth, mounting height, and available tweeter location before purchase. Install each woofer and tweeter through its supplied in-line crossover, observing polarity and keeping the crossover protected inside the vehicle. The package includes flush-, surface-, and starfish-style tweeter mounting hardware, but vehicle-specific brackets, wiring adapters, or panels may still be needed.\u003c\/p\u003e","brand":"Infinity","offers":[{"title":"Default Title","offer_id":45632036798534,"sku":"INFSPKPR503CF","price":136.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61zsYBrcEAL.jpg?v=1784392429","url":"https:\/\/audiowatt.store\/products\/infinity-primus-503cf-5-25-2-way-component-speakers","provider":"Audio Watt Store","version":"1.0","type":"link"}
