Supra is the brand name of Jenving Technology - a Swedish company founded over 30 years ago by a young former Ericsson engineer called Tommy Jenving...

Since then, many new and innovative products have been designed and manufactured by Jenving, including:

* Classic 4mm speaker cable - one of the very first dedicated audio cables designed solely for use as a loudspeaker cable - most people used lighting flex before this.....!
* Ply - low inductance speaker cables
* Swift - an easy to use XLR connector
* Rondo - a bi-wire speaker cable
* LoRad - a flexible, shielded mains cable
* Sword - a zero inductance speaker cable

Supra products are distributed around the world and across all fields where cables are required - in domestic, marine, automotive, industrial, medical and military sectors.

Indeed, Supra products are in use in many places outside the typical "home" environment, such as in hospitals, theme parks, trucks and aeroplanes.
