BBC LS 3/5A

The Falcon Acoustics Gold Badge 15 ohm LS3/5A is the only LS3/5A in production that faithfully replicates the original BBC design published in October 1976.

Hand-assembled by Falcon Acoustics in Oxford England, the Gold Badge LS3/5A is widely held to be the best production LS3/5A ever made, and follows on from the 12 years of research that led to the Kingswood Warren Special Edition.

It is the only LS3/5A to ever achieve Stereophile Class A component status, a unique accolade which has been awarded since 2021.
Falcon Acoustics is proud to continue the long tradition of the no compromise genuine British LS3/5A stretching back to the 1960’s.

The drive units are the renowned Falcon B110, and the Falcon T27 tweeter, both designed by Malcolm Jones, the original designer of the KEF B110 and KEF T27 that were specified in the original 15 ohm LS3/5A version designed by the BBC. Both drive units are handmade in the UK to ensure the highest quality, grading and consistency, and are identical to the original LS3/5a drive units. They are unique to Falcon.

The matched 15 ohm Gold Badge FL6/23 filter networks are made exclusively by Falcon in the original transformer-style to BBC Specification and contain inductors specially made in Britain for Falcon to the original larger R&D specification for better sonics, lower distortion and lower saturation. Capacitors are hand made in the UK using specially selected PP film to match the sonic characteristics of the original BBC R&D prototype version.

The cabinets are hand made from specially selected graded Baltic Ply, and use selected grade Beech fillets. They are made in Italy by specialist cabinet makers to BBC Specification, and are available in a variety of natural wood veneers (see below for pictures of current veneers) with a Tygan Cloth front grille.
