DESIGN PHILOSOPHY
We have been developing and manufacturing loudspeakers since 1977.
Our goal has never been to make a nice sound but to reproduce sound perfectly.
Artists and sound engineers spend a lifetime improving their art and designing the best possible sounds for others to enjoy. We respect this.
Therefore we only want to transform the electrical signal into an acoustic signal as accurately as possible so that the listener can hear and appreciate all the beauty and details.


TRULY UNIQUE  TECHNOLOGY
In over 40 years of building professional monitor speakers, we have acquired a lot of experience and know-how and distilled this knowledge into sophisticated, all-analogue technology. Class G/H amplifiers, CPR, AOI, ALG, dedicated drivers – all these technologies help us achieve maximum precision for your listening needs.


COMPANY
Relec SA is the company that owns and manufactures PSI Audio. Our workshops and offices are ideally located in Yverdon-les-Bains in Switzerland in the middle of a fast developing technology park.

Relec SA is specialized in designing and manufacturing very high quality loudspeakers. Apart from PSI Audio, we also manufacture Rowen www.rowen.ch as well as some custom built speakers. In the past, we developed and produced a range of studio monitors for Studer www.studer.ch

Our 1’000 square meters premises feature all the workshops necessary for the production of speakers: mechanics, woodwork, winding, cabling, PCB laboratory, PCB mounting, magnetization, assembly workshops, quality check stages, 150 cubic meter anechoic chamber, packaging, storage, etc.

Our unique and multi-disciplinary expertise in acoustics, vibratory mechanics, electronics and instrumentation has also allowed us to develop devices for other industries: seismographs that equip many bridges and dams in Europe, high precision amplifier for precision mechanical devices, measurement instruments for the watch industry, acoustic tables for the medical industry, etc.
