About the LS3/5
The Graham Audio LS3/5 revives the rare original BBC LS3/5 monitor, distinct from the more common LS3/5A. Developed by BBC Research and Development, the prototype LS3/5 used early KEF B110 and T27 drivers, but production changes led to the LS3/5A revision. Graham Audio, under license, recreates the authentic LS3/5 using bespoke Volt 110mm Bextrene-coned bass/mid driver and SEAS 19mm soft dome tweeter, with a thin-wall 9mm birch plywood sealed enclosure and removable rear panel. It delivers the classic BBC midrange beauty, vocal clarity, and surprising bass extension for its size, ideal for near-field monitoring in small rooms. Finishes include cherry, rosewood, and others.
