Infinity Kappa Perfect 6.1

Amazing!

By far the best speakers I have ever owned. I install car audio for B*** B** and hear different speakers in all kinds of cars every day but these are by far the best speakers I have ever worked with on a realistic budget. I would recommend to anyone who wants an amazing sound, just be sure you have a good amp behind it.

Outstanding clarity at high levels and durability.

I have these installed in my 2003 Cobra as well as my brothers 2003 Chevy 1500 Sierra. In both vehicles they're powered by Infinty amps (the reference 475a and the Kappa 4 channel) and both sets sound AMAZING. The x-overs have adjustable volume settings for the tweeters which enables you to set it the way you like based on their distance and mounting options and the mids are smooth and clear with no distortion or image fouling at even high volumes.
I ended up putting CDT's in my other truck and I'm starting to think I made a big mistake, I should have stuck with what I knew and got these again.
The only option I'd like to see with these is the ability to add an extra image tweeter to the X-over, but then again only CDT has that option right now so I guess I'm asking for a little much.

Incredible Speakers!!!!

I went to a local shops to listen to alpine, focal, mb quart, infinity, pioneer, jbl og blaupunkt. And the perfect series just blew me away.

The soft sound of the tweeters and the woofers produce great sound at the mid lvl.

These speakers are the best speakers I ever heard!

Screamers!

these tweets scream so loud ive had to turn the hi's down on my indash. the mids do great for just 6" when i first hooked everything up i though my subs where on, but they werent it was the 6's thumbing....great set!!

Fantastic Reproduction and Stage

I've paired these with a Pioneer D9500F 4 Channel Amp and Pioneer 80PRS headunit, deadened the doors with dynmat and I can honestly say that the quality, clarity and precision of these speakers is superb.

These speakers reproduce higher frequencies extremely well. If you're after speakers for mids and highs, don't look past these at all (Note: I've got tweeters at -3db as they were a little harsh imo).

Would recommend to supplement these with a sub or some kind to fill out the lower frequencies (I have a small 6 1/2 in a sealed enclosure).

awesome

Fully recommend, awesome speakers, clean sound :-) don't think I'll ever buy another type of speaker again

Infinity Kappa Perfect 6.1

Good sound, at OPA627A with amp. PPI art series.

best sounding speakers

I bought these speakers about 3 1/2 years ago. Just blew my perfect and Kappa 6X9's. Accidentally pushed bass booster on my head unit on full blast and blew them. best sound speaker and had them hooked to my soundsteam amp rated at 4 x 125 rms at 4 ohms and 8 volt eq to clean the sound even more.

Great set

My first time installing component set and these were easy to install. Sound great and have some good bass too. They get loud and still sound great. I have them ampd at 100w rms.

meh at best

I didn't really like this set , they weren't worth the money to me, an equally valued set from JBL did much better, the tweeters of this set were very harsh and bright, but to harsh, couldn't do some music very well.
