{"product_id":"infinity-kappa-303s-3-midrange-speakers-with-crossovers","title":"Infinity Kappa 303S 3\" Midrange Speakers with Crossovers","description":"\u003cp\u003eThe Infinity Kappa 303S is a pair of compact 3-inch midrange speakers designed to expand a compatible Infinity Kappa component system into a three-way setup. It helps fill the important vocal and instrument range between the main woofers and tweeters. This makes it a practical upgrade for listeners seeking a more complete front-stage presentation without moving to a fully custom speaker system.\u003c\/p\u003e\u003cp\u003eEach Kappa 303S driver is rated for 55 watts RMS and 165 watts peak power, with a 3-ohm nominal impedance and 93dB sensitivity at 2.83V. Its stated 200Hz to 15kHz frequency response covers a broad midrange band for clear vocals, guitars, percussion, and other detail-rich content. The compact format can suit dash, sail-panel, pillar, or other custom midrange locations when mounting clearance is verified.\u003c\/p\u003e\u003cp\u003eInfinity includes a dedicated bandpass crossover enclosure for each midrange driver. These crossovers are intended to manage the driver’s operating range when the 303S is added to a compatible Kappa two-way component system. The result is a structured path for adding a dedicated midrange channel rather than running the speaker from an unrestricted full-range signal.\u003c\/p\u003e\u003cp\u003eThe Kappa 303S is specifically designed as an upgrade path for compatible current-generation Kappa component sets, including the Kappa 503CF, 603CF, and 693C. Those component-system crossovers can be switched from two-way to three-way operation when used with the supplied 303S crossover assemblies. It is not intended as a direct interchangeable upgrade for previous-generation Kappa systems with different crossover connections.\u003c\/p\u003e\u003cp\u003eThis package is sold as a pair and includes grilles, mounting hardware, foam gaskets, connection cables, and crossover enclosures. Its 3-inch class size and shallow mounting profile can make it useful where larger midrange drivers will not fit. Confirm cutout diameter, mounting depth, component-system compatibility, amplifier stability, and available mounting space before installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDedicated 3-Inch Midrange:\u003c\/strong\u003e Adds a focused midrange driver to a compatible three-way front stage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBandpass Crossovers Included:\u003c\/strong\u003e Helps route the appropriate frequency range to each midrange driver.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e55W RMS Handling:\u003c\/strong\u003e Supports amplifier matching up to its continuous power rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-Ohm Nominal Impedance:\u003c\/strong\u003e Matches the low-impedance design used in compatible Kappa systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e93dB Sensitivity:\u003c\/strong\u003e Supports strong output from modest amplifier power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKappa Three-Way Upgrade Path:\u003c\/strong\u003e Integrates with select current-generation Kappa component systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe Kappa 303S package combines compact 3-inch midrange drivers with separate bandpass crossover enclosures, protective grilles, foam gaskets, and supplied mounting hardware. The speakers have a 92.5mm external diameter and a compact physical footprint suited to installations with limited surface area. Grilles and logo accessories are included for installations where the drivers remain visible.\u003c\/p\u003e\u003cp\u003eFor intended Kappa-system use, connect each supplied 303S crossover to the matching connection on a compatible Kappa 503CF, 603CF, or 693C component-system crossover and select three-way operation on the main crossover. Verify the 2.877-inch cutout requirement, 1.25-inch top-mount depth, and available rear clearance before cutting panels. Use the included foam gaskets to help seal the mounting surface, and ensure the amplifier is appropriate for a 3-ohm speaker load.\u003c\/p\u003e","brand":"Infinity","offers":[{"title":"Default Title","offer_id":45632018284614,"sku":"INFSPKKA303SAM","price":241.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/51_DlEfWnKL.jpg?v=1784391981","url":"https:\/\/audiowatt.store\/products\/infinity-kappa-303s-3-midrange-speakers-with-crossovers","provider":"Audio Watt Store","version":"1.0","type":"link"}
