Our take on the Infinity Kappa 107t

Add some sparkle and life to your system's sound by putting in a set of Infinity Kappa 107t tweeters. You'll hear details in your music you didn't know were there, and experience a startling improvement in stereo imaging — particularly if you're used to listening to factory speakers mounted low in the doors.

These dome tweeters blend metal and ceramic materials to faithfully reproduce the highs the way they were recorded. External crossovers prevent lower frequencies from reaching the tweeters and compromising sound quality. The included mounting hardware gives you plenty of placement options, while Infinity's Starfish™ mounting bracket simplifies mounting these tweeters in existing factory tweeter locations.

Features

Material: Each tweeter features a 1" edge-driven MMD (Metal Matrix Diaphragm) dome, resulting in increased power handling and reduced distortion at high output.

Mounting: The I-Mount tweeter mounting system and Starfish mounting brackets give you several different ways to mount the tweeters:

  • I-Mount Tweeter Mounting System: The tweeters can be surface or flush mounted with Infinity's innovative I-Mount system:
    • Surface Mount: Surface mounting the tweeters involves screwing the surface-mount cup to the mounting location, then inserting and locking the tweeter into the cup.
    • Flush Mount: Flush mounting is made easy through the use of the threaded flush-mount adapter and plastic locking nut. Once a cutout is made, the flush-mount adapter (with the tweeter installed) is inserted into the hole. The large plastic locking nut is threaded onto the adapter (from behind the mounting surface) to hold the complete assembly securely in place. When flush mounted, the tweeters may be angled for optimum response and imaging.
  • Starfish Mounting Brackets: The Starfish mounting brackets allow the tweeters to be installed in factory locations behind the grilles:
    • Surface Mount (behind grille panel): Once the Starfish bracket is trimmed, it is screwed to the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
    • Flush Mount (behind grille panel): Once the Starfish bracket is trimmed, it is dropped into the cutout in the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
    • Bottom Mount (to grille panel): Once the Starfish bracket is trimmed, it is secured to the underside of the grille panel. The tweeter must be inserted into the bracket and locked into place before the bracket is mounted.
    • Flush Mount (in-dash location): Once the Starfish bracket is trimmed, it is dropped into the cutout in the dash. Then, the tweeter is inserted into the bracket and locked into place.

Crossovers

Crossovers: Kappa tweeters include computer-optimized, voice-matched crossovers, using audiophile quality air core inductors and polypropylene capacitors. The high-pass crossover point is 3.5kHz. Each crossover has 23" input leads and 33" output leads. The input leads terminate with bare wire and the output leads terminate with female quick-slides.

Crossover Dimensions: W=3.525", H=1.136", D=1.769"

Kappa name, Alpha quality

Written By Greg, Louisville on Monday, July 07, 2008
 
Worked out great in my 08 GTI door location.
Crossovers are smaller than most, that's great! made it easier to mount behind door panel.
Noticeable improvement over stock!
The starfish mounting didn't help me at all but nothing beats hot glue for tweets in stock locations, guess that's why the oem's use it.
Almost gave them a 4star cause I was all hyped about the mounts but they would work good in a more standard location(flatter).

2001 Grand Cherokee Ltd. TweeterReplacements...

Written By Rick, East Windsor,NJ on Friday, June 20, 2008
 
I purchased the Infinity Kappa 107t as a replacement for the dash
mounted tweeters in my 2001 Jeep Grand Cherokee Limited, with the
Factory Infinity Sound System, that were blown out. The dealer wanted a
crazy price for the OEM Speaker, so for less than half the price of one OEM
Speaker, I got a set of New Speakers. With a little creativity, I bent one of
the old style radio mounting straps,into a square U shape, mounted one of
the plastic brackets that came with the 107t to the metal strap, cut the
wires off my old speakers,put on heat shrink tubing,soldered the wires
on,heated the heat shrink tubing and screwed the speakers back into the
OEM location, then did the same for the other side Put the Dash Panel back
on, and what a sound from those tweeters! They are fabulous! The entire
project took less than an hour to complete. Plus when you look at the
dash, you can not tell anything was changed, unless yopu turn on the
Radio and hear the clarity,especially with the CD's! A Great Product at a
Great Price! A 10+++ Rick : )

Smooth!

Written By Todd, Ventura, CA on Monday, April 21, 2008
 
Phenomenal sound from these little tweeters. No distortion or harsh sounds. Incredibly smooth even at high volumes. They added great definition to my stock stereo in my 1998 Mitsubishi Eclipse Spyder, replacing the original in-dash tweeters (which disintegrated a little bit ago). The in-line crossovers were easy to stash in the dash under these to keep the original look to the vehicle as well. I eventually added a MTX Thunderlink to round the whole system out. Thanks to Crutchfield and all these thoughtful reviews. Well worth the price!

First non-Polk tweeters!

Written By Brandon, Ruston, LA on Sunday, February 10, 2008
 
I took a flyer on these and I am impressed. These are my first hard dome tweeters and first non-Polk. I have one pair mounted on the columns and the other custom mounted in the information/light panel on a '07 Dodge Ram QC, powered by an Alpine MRP-250. Nice addition. Great fit with my otherwise all Polk system.

The best

Written By Waymond, Modesto, CA on Monday, April 30, 2007
 
This tweets are the best. I did a flush install and the look great. These are very powerful. Right now I have then hooked to deck with no amp and they sound amazing. Great addition to Infinity Kappa 6X9 and Infinity Reference 6 1/2 that I also own. If you need powerful and excellent sounding tweet to add to your system you can't go wrong with these.

Outstanding in my Silverado

Written By wfs, Florissant, CO on Monday, July 31, 2006
 
First, let me say these tweeters are an excellent addition to a stock stereo. Most of us who know our pick-ups understand that it is very difficult to get the sound 'just right'. That said, these babies really help.

I placed the tweeters using surface mount (no drilling or cutting) with double-sided 3M tape near the A-pillars on the top of the dashboard so that they reflect off the windshield dispersing the highs very nicely at ear/head level.

But wait, there's more!
Add an amp and sub-woofer with component speaker up front and some decent plate speakers to the back and you have a miracle!

I have had them for over 4 years. That should help those considering their potential longevity. No problems at all. They are worth every penny.

Infinity Kappa 107t

Written By Scamp, Dublin, GA on Friday, October 28, 2005
 
I installed these seperates two days ago and so far I am pleased. I am very particular and honestly this tweeter does not produce the sound I was looking for. My other four interior two-way speakers are the Infinity Reference 6021's and I absolutely love the SMOOTH upper frequency sound they produce. I added these Kappa 107t's to add some image to my front soundstage, and when I wired them in parellel with my Reference door speakers (powered by a 40W RMS Alpine AMP), the tweeters over powered and drownded out my 6½'s. I had to disconnect and rewire to my Kenwood headunit (50Wx4) to reduce and even out the sound. Much better! These tweeters produce a very sharp, metallic high which is crystal clear, but the sound does not balance well with the Reference series speaker. If I were to choose again, I would get the silk dome Reference tweeters, or install a component woofer in the door panel. I give this product 5 stars because they are an excellent tweeter, but not fit well with my setup.
