Real Fullrange Driver

Ether 7.1.12 is totally handcrafted real full range alnico driver, produced with unique purpose: to play the Music!

That’s why its essence, all of its components and appearance is subordinated to this general dedication.

Moving parts topology, voice coil, magnetic and demodulation system, chassis, T/S parameters, frequency response and all the rest details are consequence from this zealously pursued goal:

MUSIC FRIENDLY reproduction

Construction of Ether 7.1.12 real full range driver is a result from development and numerous empirical experiments for more than 20 years!

If you want to hear the air in your music…


Every single Ether 7.1.12 is totally handcrafted and tuned!

Ether 7.1.12 is a Real Full Range Alnico Driver

Ethet 7.1.12 has an Unique Cast Alnico Magnet and Demodulation system, designed to reproduce as accurately as possible signals with subtle levels.



Etheraudio statement is that Cast Alnico 5.6 magnet system is closest to the maximal phase correctness which allows most accurate positioning of the signals with lowest levels. This in turn allows full depth and closest to the real reproduction of the sound. 


Each Ether driver or Ether driver based horn loudspeaker enclosure, requires minimum 100 hours of play up in order special magnet system and elasticity of materials to achieve normal working condition and listed parameters.
