Tweeters

Tweeter Material: Each tweeter features a 3/4" 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 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.

Crossovers

In-line: Each tweeter has an in-line 2.5 kHz high-pass crossover.

Connections: Each crossover has 23" 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) and the input leads have bare wire.

Crossover Dimensions:

• Length: 2.55"
• Width: 0.95"
• Height: 0.91"

Specifications

True Four Ohm Impedance Technology: The speaker's 3-ohm impedance combined with the impedance of your speaker wire provides a true 4-ohm load to your connected head unit or amplifier.

Power Handling: Although Infinity rates the 075tx speakers at 45 watts RMS (continuous average), they also recommend amplifiers with a power rating from 5 to 75 watts RMS.
