Auratron Systems

The fundamental design philosophy for all of Auratron Systems equipment is:

  1. Achieve the lowest IM (InterModulation) Distortion, even at the expense of other generally accepted measures of quality and aesthetic styling features.
  2. Achieve the lowest Harmonic Distortion.
  3. Provide all of the necessary controls required to easily and accurately achieve a pleasing spectral balance with any recording / music source, volume level, or listening environment.


Our equipment represents a viable alternative to the mediocrity of conventional audio. Our technology is not based on any current “fad” and we do not manufacture “goofy sound effect devices” — our design philosophy is based on solid engineering / electro-acoustic theory. The equipment presented in this brochure is not intended for the average consumer, but rather for those who expect and can appreciate the highest level of quality and performance in audio equipment.

None of our components or systems have been “tweaked” to achieve a particular sound character while playing a certain “kind of music”; it is a popular myth that a particular type of equipment or system is needed to obtain a pleasing sound character with a particular type of music. We do not subscribe to the idea of deliberately introducing “soft distortion” artifacts to mask “harsh distortion” present in the source material. If the music source material is not flawed, all of our systems will yield exceptional sound character, regardless of the “kind of music”.

From the beginning we realized that passive crossovers for speakers inherently can’t work and introduced the industry’s first 4-way Stereo Electronic Crossover. It soon became apparent that a whole category of speaker response anomalies could easily and accurately be corrected by incorporating appropriate compensation into the crossover sections without introducing additional active gain stages. It should be noted, however, that electronic EQ (whether active or passive) absolutely can not compensate for mechanical mis-alignment of speaker drivers; thus all of our speaker systems feature user-adjustable Time-Alignment*2 for the drivers.

While other manufacturers are perpetuating obsolete technology, we offer systems with a level of quality that has previously been unattainable — at any cost.
