I have had them all and at higher volume levels, nothing sounds cleaner and has higher headroom before clipping than Kappas. I have (12) of these along with (32) 63.9is, (8) pioneer pro TS-W3002D4 and (2) Buttkicker transducers in my excursion. The volume levels these speakers are capable of with the proper power and crossovers is staggering. Its like hearing a pin drop at 200 db...

I have a Hummer H3 w/ the speakers very low to the floor, even thou I had Infinity Kappa two-ways in the doors, the sound stage was at my feet. I purchased these 10.9T and replaced the Hummer tweeters in the pillars. Immediately, the sound stage was ear level, and detailed. These tweeters are bright, and really highlight guitar and saxophone. I had to re-eq the whole truck based on these, but it is nite & day sound-wise. Highly recommended.

Pro
Easy to install w/ many mounting options
Easy to connect to my system, and crossovers were appropriate
Soundwise; bright, crisp, defined and musical w/ a hint of highmids mixed in

Con
might be too bright for some (and therefore require EQ to get right in the mix)
Tweeters are not small- and although they fit into my pillars, the holes required were bigger than standard

best sounding speakers i have installed in one of my cars

Nice tweeter love all the install options, sounds great I put them in my 86 bronco. I am going to get another set. Even wen my RE Audio xxx15d2 hits that low bass i can still hear the tweeters realy good. So buy them.

Another great product by Infinity! I have always used Infinity products in most of my cars for aftermarket mids & highs.. These Infinity Kappa Tweeters sound amazing! I used them to replace the tweeters on the dash pillar of my SUV. I would highly recommend these to anyone who wants to add crisp, clear highs to their system.

I would definitely recommend these tweeters to anyone. They are some of the best i have ever heard and extremely easy to install

Great tweeters I have had these for about 3 months and sound great and get loud but installation was tricky in the factory location of a 2007 camry. had to fabricate my own bracket

I thought these tweeters would fit my car, but even after trying to modify the mounts, they were too big.

Replaced these in my mom's 2006 chevy impala. Works like a charm without over doing the power. I would recommend this to anyone that loves clean high end sounds.

These tweeters really set off my system. I originally had the infinity reference 1031T's and blew them pretty much right off the bat. I went ahead and shelled out the money for these and they've been at it perfectly ever since. I've always had really good experiences with Infinity and these are no exception. The installation can be tricky because they're 2'' instead of the easier and typically stock 1'' but it can be done with a professional look. If you're going to get component speakers, definitely get the set that include these tweeters as opposed to the reference 1031T's...you'll be happy you did in the long run.

As many know, Infinity Kappa's are awesome speakers. These tweeters made a huge difference. I am confident these will last for a long time. I replaced these with ten year old infinity's that were in the car. Those still sounded good but could use the upgrade. Just don't lose the allen wrench it comes with. It is a custom size. Found that out the hard way.

These tweeters are a very good buy. I have them in my 99 grand am and they easily outplay the other 8 tweeters i have in there. Which are spl's, and kenwood's. These tweeters are very clear and very loud. I will definitely be replacing the others with more of these. GREAT BUY.
