## Questions & Answers

**Q: What are the total measurements of this speaker?**
A: Thanks for your interest in our product. 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. If you need more help, please reach out to our Customer Support.
