I purchased these Infinity Kappas to install in my HD RoadGlide fairing. This was the third set of speakers to be installed in this motorcycle. They were replacing some Polk Audios that had failed after only about 3 hours of use. Overall, I am very pleased with the construction, robustness, and of course sound. Being mounted in a motorcyle fairing limits the amount of bass that can be generated but these do very well despite that limitation. There is very little to no distortion at elevated volumes and the music is clear at 80 mph!
I put these in my Toyota Tundra and I'm very pleased with the sound quality. They sound much better than the Polks in my kids car. Now they want to upgrade after hearing the difference. Also, OCS has the best deal I've seen on these speakers, by far. First time customer, I'll be back...
I bought these as an upgrade speaker for my 2014 Harley street glide. This is a nice speaker but is a very tight fit in the OEM space. I have not been able to dial them in yet but i think it is my setup. I also added the RF PBR300X2 amp. Currently i am not getting any bass out of these speakers but again i am thinking i am not set up correctly. Good speaker for a great price. Hopefully i can get these things to sound better!
I bought a pair of these for the rear of my audi because I was reluctant to hack up and install component tweeters. Surprisingly, these sounded just as good as the component systems I've used. The tweeters can be aimed, and attenuated without fiddling with a hidden crossover. I like them so much, I bought two sets for my Wrangler.
