Product Information

Upgrade Your Audio Experience

Don’t settle for inferior sound in your vehicle. We all spend a lot of time in our cars, trucks, and SUVs, so why not get some better audio to make the rides more enjoyable? Install the Infinity KAPPA52.11i 5-1/4” 2-way coaxial speaker system into your vehicle and hear the difference between stock speakers and quality aftermarket speakers. Not only are the Infinity Kappa car speakers better-sounding, they also feature a 2-ohm impedance so that you can extract maximum power from the audio system currently installed. You’ll be smiling from ear-to-ear for a while, we think.

Nuances Emerge

The KAPPA52.11i coaxial speakers feature edge-driven soft dome tweeters that excel at reproducing high frequencies. Each cymbal crash or vocalist have their own stage to perform on and details emerge that you’ve never heard before – and we are talking about tracks that you’ve listened to dozens of times over. Since the tweeters are soft dome, they are warm and natural-sounding in comparison to some of the metal dome tweeters that are out there. Again, we anticipate lots of smiles when you listen to these Infinity speakers.

Accurate Bass Performance

Infinity combines two great technologies to create the incredible midbass woofers that are found in the KAPPA52.11i speaker kit. The cones of the woofers are made from glass-fiber which is sturdier and lighter than most polypropylene woofer cones so they hit harder and require less power to run well. The woofers cones also have increased surface area thanks to their Plus One™ design so they will produce lower, fuller-sounding bass response.
