Stirling Broadcast LS3/5a V2 Monitor Loudspeaker

ls36 2013_TAS_edChoice

Built under license from the BBC, our LS3/5a V2 was our first design collaboration with Derek Hughes, bringing the LS3/5a back into production after the Kef stopped the manufacture of the T27 and B110 driver units.

Drawing upon his extensive experience of the LS3/5a, which reaches back to his work for the BBC in the 1970s, Derek managed to retain the legendary sonic character of the original, capturing the much loved vocal abilities of the classic 15 ohm version, whilst combining this with the faster more modern sound of the newer 11 ohm version. 

LS3/5a Award

As a result our LS3/5a V2 has improved and extended bass response with greater handling of dynamics, and won the 2005 HiFI News award for it’s category of loudspeakers.

Mass-produced versions of the LS3/5a used a compromised cabinet with 12mm walls - in contrast the Stirling LS3/5a cabinets are modelled on the famous 001/002 pair featured in the Hi FI News ‘shootout’, which were built in-house by the BBC and used as their references. 

LS3/5a 001/002

These cabinets followed the “lossy” thin walled cabinet design philosophy developed by BBC Research Department at Kingswood Warren, using 9mm thick cabinet walls instead of 12mm. 

LS3/5a 001/002

Our LS3/5a V2 version therefore combines the very best of the traditional BBC LS3/5a with modern design and manufacturing by using custom high quality drive units in thin wall (9mm) birch plywood cabinets, damped using double layers of bituminous pads. The high-quality crossover followed extensive development with both computer aided design and traditional A-B listening used to voice the Stirling LS3/5a V2 against BBC 001/002.

The new speaker ideally requires 24 inch high stands, such as those supplied by Something Solid.
