Stirling Broadcast LS3/5a V3 Monitor Loudspeaker

LS3/5a

Building upon the strengths of the well-received Stirling Broadcast LS3/5a V2, the Stirling Broadcast LS3/5a V3 “Ultra Low Distortion Monitor” retains the same drive units and thin-walled cabinet but adds a new, higher-specified crossover to attain much lower levels of distortion and higher levels of transparency.

The new crossover, designed by Derek Hughes, is considerably larger, being just 16mm smaller all-round than the front baffle, and incorporates much larger components, including closely matched air-cored inductors to remove the saturation experienced with ferrite or iron cores. The new crossover adds 28% to the weight of the LS3/5a V2 loudspeaker, namely 1.2kg!

Additionally the crossover is mounted on the rear panel, as for the Kingswood Warren prototype versions, to further decrease distortion.

Due to the higher cost of the new crossover, the Stirling Broadcast LS3/5a V2 will remain available for those situations were ultimate transparency is not required. In particular, to fully realise the additional capabilities of the V3 crossover, the quality of the users source and amplification is paramount.
