## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Audiophile grade audio that can fit your OEM system.
*by  on Reviewed in the United States July 14, 2026*

Installed these on my Grand Highlander Limited with JBL OEM sound, We had to make a base plate because these are 3 inches instead of 3.5 from the factory and we did trim a little of the oem underplate for the speaker covers so they fit perfect. They sound astonishingly good, voice is very clear, I can hear stuff that previously where disguised as noise the highs are so detailed and smooth Im amazed on how good this sound.

### ⭐⭐⭐⭐⭐ The price can't be beat for the quality.
*by  on Reviewed in the United States July 7, 2025*

Why did you pick this product vs others?:Sound quality it super.

### ⭐⭐⭐⭐⭐ Crossovers have 3 way plug not two way plug won’t work for my infinity kappa crossovers
*by  on Reviewed in the United States October 12, 2021*

Sound amazing, problem is they won’t work with my crossovers as they state they will a simple plug and play. 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.
