Falcon Acoustics has announced the ‘Kingswood Warren' model, a meticulous remaking of the ‘no compromise' prototype created by the BBC in 1974, before commercial production.

Falcon Acoustics is remaking history with its authentic hand-made re-creation of the BBC's first LS3/5A ‘no-compromise' prototype design, conceived two years before the first commercial production in 1976.

Named in memory of the BBC's Kingswood Warren Technical Research Department, where the LS3/5A first took shape, Falcon's ‘Kingswood Warren' Limited Edition represents the closest possible replication of the BBC's final prototyped specification.

Falcon Acoustics Kingswood Warren

For the Kingswood Warren Limited Edition, Falcon has created screw-backed, critically damped cabinets from specially selected and graded 9mm Baltic Ply which are then finished in a Teak veneer.

The speakers are built to look, perform and sound precisely as they would have done in 1974. Falcon used the original BBC LS3/5A cabinets Nos 3 and 4, and hand-written notes from BBC engineering staff to guide production.

Falcon Acoustics Kingswood WarrenThe BBC created transformer-style inductors for prototyping, using a size of radio-metal lamination that is no longer available and with an ingenious clamping system that allows for very accurate inductance value setting. Thanks to Falcon's founder Malcolm Jones, Falcon had enough material to be able to replicate these critical components for the 50 pair production.  

Again, referring to the original BBC specification, it calls for capacitors using a Polycarbonate dielectric film, the production of which ended almost twenty years ago. After three years of searching, Falcon discovered a limited supply of the film and has commissioned Falcon Polycarbonate capacitors to re-create the exact same BBC crossover from 1972/74, which was used to finalise the LS3/5A design. Polycarbonate capacitors offer exceptional stability, speed, accuracy, and unrivalled depth of tone and soundstage.

This unique provenance is possible through Malcolm Jones who, as Chief Design Engineer at KEF, designed the originals in the 1960s.

Finally, bespoke rose-gold plated terminals and badges, and an antique-leather style folding-front presentation case complete this Limited Edition of 50 pairs. No further replications are possible. Falcon Acoustics plans to present a pair of ‘Kingswood Warren' Limited Edition LS3/5As to the BBC.

Experience the Kingswood Warren Limited Edition

The ‘Kingswood Warren' Limited Edition LS3/5As make their UK show debut at the Bristol Hi-Fi Show Fri 22nd - Sun 24th February, Room 430.

Typical retail price (inc VAT) £6495 pair and will be available from March 2019 while stock lasts.
