Built under license from the BBC, the Stirling Broadcast LS3/6 Reference Loudspeaker is a 3-way design by Derek Hughes. Using modern components he has designed the Stirling Broadcast LS3/6 so it remains faithful to the original BBC specification and much loved sound, while offering greater power-handling than the original, an even smoother frequency response, much lower colouration and better dispersion.

Derek Hughes has done this by taking advantage of the greater consistency and linearity of our custom-designed, modern drive units, integrating them by using both computer aided design and listening tests with a very high quality crossover. A super-tweeter further improves the already excellent high frequency response of the original LS3/6 design.

The Stirling Broadcast LS3/6 cabinets adhere to the “lossy” thin walled cabinet design philosophy developed by BBC Research Department at Kingswood Warren, although the rear panels are now glued instead of screwed as this has found to yield more consistent results without loss of performance. The high quality cabinets use 9mm birch plywood with double thickness damping pads and are finished in beautiful pair-matched wood veneer with a matt lacquer finish.

The new speaker ideally requires 400mm high stands and we have partnered with Something Solid and Appollo to ensure the correct stands are available. Interested customers should contact us, Something Solid, or Appollo for further details.

The LS3/6 is sold with our standard 5 year warranty on the drive units and crossovers.
