The loudspeaker driver with the tweeter placed in the middle of the woofer.

Guy R. Fountain, Tannoy’s founder, had his engineer Ronald Rackham design a driver in which the tweeter sits in the middle of the woofer. The sound then comes from a single point.

The driver was built into large floor-standing speakers and used in many studios. The principle is found today in several brands, including KEF.

Materials: Paper cone, metal frame, compression driver in the centre

Manufacture: Developed by Tannoy in Britain and on the market from 1947.
