The Falcon Acoustics Classic 15 ohm LS3/5a, fully Licenced by the BBC, and hand-assembled by Falcon in Oxford England. It is the only LS3/5a now in production that is recognised by top reviewers to faithfully replicate the original design published by the BBC in October 1976.

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.

The matched 15 ohm BBC Specification 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 specification.

The cabinets are made from specially selected graded Baltic Ply, and use Beech fillets Cabinets. They are British made 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.
