MoFi Electronics MoFi Edition LS3/5a Monitor Loudspeakers By Falcon Acoustics

Hand-built in Oxford England by Falcon Acoustics the MoFi Edition Monitors are a limited run of the legendary LS3/5a speaker. Manufactured under license from the British Broadcasting Corporation and built in accordance with their rigid specifications, Falcon speakers are the only LS3/5a on the market that faithfully replicates the original BBC design published in October 1976.

Available in an exclusive Black Ash cabinet and utilizing Falcon’s proprietary hand-built drivers and filter networks these speakers offer not only a stunning fit and finish but a sound that will make you swear you’re in the recording booth.

The result of nearly 2 years development, the Falcon LS3/5a is a true British-made classic 15 ohm LS3/5a. It continues the long tradition of the genuine British BBC-Licenced 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 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 hand made from specially selected graded Baltic Ply, and use selected grade Beech fillets. 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.
