The Studio 4 transmission line speaker continues to demonstrate TDL's monitoring approach to loudspeaker design.

The sum of the component parts provides a loudspeaker system of extraordinary merit, demonstrating to the full the virtues of transmission line loading, whilst retaining the proportions of a speaker compatible with domestic surroundings.

Studio 4_Monitor

Bought it mid of the eighties. Still perfectly working. Bi-amped. Low frequencies are a breeze, T.L. at its best. Unluckily production stopped. In case, difficult to find the original replacement part.
