Product Description

The Stirling Broadcast BBC LS3/6 Reference Loudspeakers are a new 3-way loudspeaker design for Stirling Broadcast by Derek Hughes to be as close to the original BBC LS3/6 specification possible with modern components. Released in December 2011, this new model was built under licence from the BBC, only possible after submission to the BBC for rigorous examination to ensure they adhered to the original specification.

The original BBC LS3/6 Loudspeaker was designed as a monitoring loudspeaker for outside broadcast use, as with the smaller LS3/5a speaker. Once the design was finalised Rogers became one of the first companies to produce this complicated design. A summary of the history of the design can be found on Mark Hennessy's website.

The Stirling Broadcast LS3/6 takes advantage of the greater consistency and linearity of modern drive units compared to when the LS3/6 was originally designed. A very high quality crossover is used to mesh custom made drive units, including a super-tweeter, into thin-wall, birch plywood (9mm ply) cabinets with double thickness rubber damping pads and screw-on, removable front and rear panels, as per the BBC "lossy" cabinet design ideal, as also seen in the Stirling version of the LS3/5a.

This new version offers greater power-handling than the original versions from the 1970 and 1980s, and offers the smooth frequency response, very low colouration and good dispersion commensurate to addearing to the specifications of a BBC monitor.

Bookshelf speakers in the loosest definition of the phrase, the LS3/6 stand proud at 24" high, 12" wide and deep. An exciting addition to the Stirling Broadcast range to compliment the smaller LS3/5a speakers (see photo above for illustration of how they compare in size). For the best sound, use these speakers with 400mm high stands (Apollo and Atacama offer suitable matching stands).
