135W peak power handling (45W RMS)

Infinity REF-075tx 3/4-inch (19-millimeter) component tweeters handle a full 135 watts peak power and a very respectable 45 watts RMS. This power rating ensures that you’re choosing speakers that will work well with a varied range of products, whether you’re installing them as an upgrade to a premium factory sound system with existing component separates or if they’re connected to an aftermarket head unit or dedicated power amplifier to enhance an existing system. (If you’re planning your audio-system layout recommended power for REF-075tx tweeters is anywhere between 5 to 75 watts.)

Edge-driven fabric soft-dome tweeter design

The powerful, edge-driven fabric soft-dome tweeter design in the 3/4-inch (19-millimeter) Infinity REF-075tx component tweeter features greater power handling and lower distortion than conventional tweeters of similar size. These enhanced performance characteristics allow a richer level of detail in high frequencies and, in particular, vocal clarity that is lifelike because of the improved radiating patterns and power handling in combination with the included passive filter network.

I-Mount tweeter-mounting hardware

The Infinity REF-075tx component tweeter includes the I-Mount tweeter-mounting system, which allows easy flush mounting or surface mounting, giving you more installation options. In addition, the speaker includes a special Starfish bracket system that allows you to mount the tweeter in a factory dash or door speaker location originally intended for a larger midrange driver – up to 3-1/2 inches (87 millimeters) – and still easily install it behind the factory grille.

High sensitivity (93dB@2.83V/1m)

A speaker featuring high sensitivity allows a wider range of power to have definitively high volume levels without overdriving the audio system. Featuring sensitivity of 93 decibels at 2.83 volts / 1 meter, the REF-075tx tweeters achieve excellent volume and musicality with as little as 5 watts RMS. These numbers mean simply great performance overall with even very moderate power driving the speakers. It makes the REF-075tx tweeters an ideal replacement for premium factory-installed systems where there are already component locations with dedicated tweeters as well as for any aftermarket installation, including adding an extra tweeter to lift and direct the sound to the listener’s ears.
