Introduction

Transducer Developments Limited was started in the 1970’S by John Wright, for over 30 years TDL have been the supplier of high quality loudspeakers, pioneering the transmission line principle.

Originally using drive units for use in transmission line speakers, the in-house production facilities for loudspeaker drivers and cabinets enabled TDL to develop speakers without the constrain of brought-in components from external suppliers. TDL went onto develop floorstanding and bookshelf speakers using a ‘reflex’ version of the transmission line technology, developing an affordable complete range of competitive speakers.

TDL now works under this ethos to produce competitive bookshelf and floor standing speakers for an ever changing consumer market.
