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