Infinity Reference REF757T Reference Series 3/4″ textile dome tweeters

Features

Mounting Options: The tweeters include the I-Mount tweeter mounting system and Starfish mounting brackets, offering multiple mounting configurations; flush-mount and surface-mount. The surface mount pods are mounted to a threaded, hollow shaft and have a ball-and-socket joint, so they can be turned in any direction, and angled to approximately 40˚:

• I-Mount: 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 housing and plastic locking nut. Once a cutout is made, the tweeter is installed in the flush-mount adapter, then into the flush mount housing and 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:
  • Bottom Mount: 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.
  • Surface Mount: Once the Starfish bracket is trimmed, it is screwed to the top of the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
  • Flush Mount: There are two sets of tabs to flush mount the tweeter in the Starfish bracket, yielding different mounting dimensions. The upper tabs mount the tweeter completely below the opening and are glued in place. The lower mounting tabs are screwed in place and result in a mounting height just under a half inch. Once the bracket is mounted, the tweeter is inserted into the bracket and locked into place.

Dimensions:

Crossover Connections: Each crossover has 24″ input leads and 33″ output leads. The output leads are terminated with female quick-slides (that mate to the male quick-slides on the wire attached to the tweeters). The input leads are not terminated (bare wire).

Crossover Dimensions:

• Length: 2½”
• Width: ⅞”
• Height: ⅞”

High-Output Design: The 3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring, extracting more power from factory (or aftermarket) receivers. This results in clearer, richer sound for the listener.
