Review: Good quality and has more thump and clarity than walmart speakers like sony or pioneer. Only complaint i have it's Chinese and one of the speakers had a Crack in the plastic but I think that was from shipping because the box was rough looking. Im planning to buy another set soon. Review: I own a Ford Explorer Limited 2013, I knew I wanted to upgrade the speakers, not the Amp. So I went with Powerbass speakers, amazing woofers, and their tweeters were much better than the OEM tweeters but not by much. I wasn't happy with the Powerbass 3.5 speakers and decided to upgrade to the Infinity Reference 3.5 and they made such an amazing difference. So I bit the bullet and bought these. Before I continue, I am an audiophile, music and the sound of music is very important to me. I connected these and was shocked on how great they sounded compared to the OEM and the Powerbass tweeters. These blended in well with the stereo, I was able to listen to all of my music that I love loud without it overbearingly hurting my ears, I listened to these on my way home from work for two hours straight, and I can say that there was zero ear strain. Now, please for the love of Christ and all spirits and angels that represent music! do not test these tweeters out with mp3's please! Show these tweeters respect and put in a CD, or listen to satellite radio, or use hi res music to test them. Mp3s do not have the musical capacity to show these tweeters off. With that said, do they sound good with mp3s, yes, but to get the full bloom of these, feed them great sounding music. I tested these at first with hi res music downloads from desertcart, first was Pearl Jam Black, miles Davis kind of blue! I then threw in a CD and played The Eagles Hotel California live SACD and wow.... I was so impressed with the detail that these were able to bring out with these songs. I then went to XM and put on the Diplo house music station and these really shined there! Now, these did not clip on to where the tweeters go in my explorer, I had to Dremel down one of the connectors that came with these in order to get a tight fit. These are superior to the OEM and Powerbass, they will not cause ear strain, they will not give you a headache. They play the music perfectly at any volume. I can compare these tweeters to the very expensive Focal tweeters that are $600. ## Features - Kappa edge-driven silk dome tweeters equipped with oversized voice coils deliver silky smooth highs with impressive thermal power handling and 40kHz high resolution. - Infinity’s glass fiber woofer cones are lighter and stiffer with more cone-area than the competition, delivering increased low-frequency output and higher efficiency.

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.
