About 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.

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.

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"
