I did a search and didn't find any references to these speakers at all. I found a pair on sale for ~88 dollars and wondered if anyone here has heard them?

I actually just had them installed in the rear. They sound really good, huge difference over stock. They fit fine with no modification. Definitly amplify them. Hope that helps.

I had the kappa's installed in my car, and they are absolutely amazing. I also have the tweeters as well. Great addition and well worth it, IF you are conscious of volume and sound quality.
