Our Infinity Kappa 303S has a Top-mount Depth of 1 1/4 (Inches), a Bottom-mount Depth 1 9/16 (Inches), a Cutout Diameter 2 15/16 (inches), and a Mounting Height 0.343 (Inches). **Q: Can I use this with infinity kappa component or coaxial speakers?** A: Yes. Our Kappa 303S is compatible with the Infinity Kappa Series component system. **Q: Can I wire the crossover to the amp and not through another crossover?** A: Our Infinity Kappa 303S includes crossovers that can be switched to 3-way mode. If you have a 3-way system, one crossover needs to be wired to another crossover, and the other connects directly to your amplifier. Please note that these midrange drivers are designed for use with the Kappa 603CF, 503CF, or 693C 2-way component sets. **Q: What frequency ranges does the crossover cover?** A: The crossover point of the Infinity Kappa 303S is 300Hz. If you're planning a three-way setup here's the recommended frequency range in setting up the crossover Woofer to Midrange: 200Hz or higher. Do not go below 200Hz. Midrange to Tweeter: 2.5Hz or higher. Do not go below 2.5kHz. You may select the frequency that gives you the best sonic results. A good starting point is 500Hz and 5kHz, and then you can work your way up or down until you find the best settings.

My crossovers require a 2 prong plug and these come with a 3 prong plug, Update, it’s a 3 way plug but you can plug it into the 2 way just make sure it’s the two wires that are the same color as that’s what sounds the best, you will have to trim a small amount off the crossover to put the cover back on to accommodate for the 3 way plug. ## Frequently Bought Together - Infinity KAPPA303S 3" (89mm) Midrange with Bandpass Crossover - Infinity KAPPA603CF 6-1/2" (165mm) Two-Way Component Speaker System - Infinity KAPPA693C 6" x 9" (168mm x 240mm) Two-Way Component Speaker System --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/368565354-infinity-kappa-303s-3-89mm-midrange-with-bandpass-crossover-enclosure](https://www.desertcart.tw/products/368565354-infinity-kappa-303s-3-89mm-midrange-with-bandpass-crossover-enclosure) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-10-10*
