Our take on the Infinity Reference X REF-075tx

by John Pollard
Infinity

Bring on the clarity
Infinity designed their REF-075tx tweeters to broadcast all the high-frequency details in your music, great news if you're suffering from a muddy soundstage in your car or you're just looking to brighten up your system a bit. These Reference X Series 3/4" textile domes add detail, help to clean up your soundstage, and provide an improved stereo image — without being shrill or causing harshness.

REF-075tx tweeter

Built for power
A large voice coil and edge-driven tweeter design help these tweeters to handle up to 45 watts RMS, while in-line crossovers allow only the high frequencies to pass. Infinity's I-Mount™ system provides adapters that allow for surface- or flush-mounting, making installation a lot easier. You can use the included Starfish mounts to place the tweeters in many existing tweeter openings.

Note: These tweeters must be used with the supplied in-line high-pass crossovers, or an appropriate external crossover. Failure to do so could lead to damage to the tweeters not covered under the warranty.

Highlights:

  • 3/4" textile dome tweeters (pair)
  • flush- and surface-mount hardware included
  • Starfish™ bracket for mounting in factory tweeter locations
  • 2,500 Hz passive in-line crossovers included
  • power handling: 5-45 watts RMS (135 watts peak power)
  • frequency response: 2,500-21,000 Hz
  • sensitivity: 93 dB
  • top-mount depth: 13/16"
  • warranty: 1 year
  • Our 60-day money-back guarantee

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.

Tweeter heaven

Written By JB, Lafayette, CA on Saturday, April 12, 2014
Crutchfield Customer Review (What's this?)
 
A fine tweeter at a fair price. I replaced the stock tweeters in my 2014 Subaru Forester and greatly improved the clarity and depth of female voices and jazz instrumentals. This is my third vehicle in which I used Infinity Reference speakers, and I've been pleased by all.
Pros:
Value, quality, variety of mounting options, sound great with OEM head unit (7-8 watts?)
Cons:
None, but some facility with tools is helpful.

GREAT Speakers and tweeters!

Written By Tim, Cross Lanes, W.Va. on Tuesday, June 25, 2013
Crutchfield Customer Review (What's this?)
 
I received my speakers and tweeters within two day. Box came in great shape. I drive a 09 Honda civic. It took about 30 mins to install all speakers. Turned them on and realized that I had made the right choice on speakers. The bass sounds amazing and is still clear as can be. I suggest these to anyone looking to buy top of the line quality speakers. 2 thumbs up!
Pros:
Sound great. Easy install. Ship fast.
Cons:
None at all!

Great tweeters

Written By Victor, San Jose, CA on Monday, August 27, 2012
Crutchfield Customer Review (What's this?)
 
Great sounding speakers, installed them on my 97 Ford Ranger, takes an experienced installer, but piece of cake if you are one. I only wished that the instructions save me a little bit of time finding the correct hole saw. Otherwise, great sounding speakers, cross-overs are compact enough to allow me to mount them to inside the door panel nicely, and was able to easly splice them to the existing wires.
Pros:
fairly easy install, sounds great, and great price
Cons:
instructions could be made a little easier with dimension of required tools to help save time during installation. Although the cross-overs were compact, I remember the days of using certain capacitors to get tweeters to perform well, but thought that the cross-overs could be made even smaller now-a-days.
