It is the year 1973. In a small, rural school building in the highlands “Eifel”, between discarded school desks and slates, a man begins to revolutionize coil technology: Heinz Wolf. With creative ideas, he is the first to develop inductor spools (coils) on hard bodies. For the innovative products the brand Intertechnik is born. The impetuous pioneering spirit does not diminish. Under the motto "Here you will find everything that makes the heart of the speaker beat better", Intertechnik has been a successful manufacturer and distributor of electronic, audio and hifi products for over 30 years. The know-how of Intertechnik is in demand with renowned loudspeaker manufacturers and large companies. The many years of consistent development of passive components and assemblies, as well as the experience in research and manufacturing have made us an excellent name worldwide. Today, Intertechnik is setting standards for loudspeaker construction from its home town of Kerpen. The high-quality electronic components from our own production - including all components for the perfect crossover network, the excellent capacitors from the Audyn brand and the innovative coils from the Intertechnik brand - are the first choice for high-end speaker technology requirements. Whether for home, in the car or on the stage.

"Hear you are" we put on our flag.

It is our goal to develop and offer the right products with the right quality, at the right price and for the right listening pleasure. It does not always have to be the expensive component, the right one for the application.

Quality, innovation and service are our top priority. Together with our partners, we develop electro-acoustic products of the highest quality. The constant increases in quality in the field of passive components and the further development of high-quality components will fulfill even in the highest audiophile requirements.
