Brighten up your car's sound system with a pair of Infinity Reference 1021t tweeters. These 1" textile dome tweeters will add sparkle and clarity to your music, and improve your stereo image — without tiring your ears.

You'll hear clean, distortion-free performance as the in-line crossovers direct only the high frequencies to the tweeters. Infinity's "I-Mount" system simplifies installation, and the Starfish™ adapters provide easy mounting of the tweeters behind panels and under factory speaker grilles.

Priced per pair

These tweeters are amazing. They have amazing highs and don't clip when tested. I installed them as part of a factory replace with a factory installed Infinity amp. They rock!

Tweeter Material: Each tweeter features a 1" edge-driven textile dome for smooth, accurate highs.

Tweeter 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.
