GRAHAM AUDIO THE BBC LS3/5A
The BBC LS3/5A
By popular demand, Graham Audio are proud to present the BBC-licensed Chartwell LS3/5A.
The LS3/5A was produced by BBC Designs Department in response to detail changes in the performance of the drive units that were originally chosen for the LS3/5 as designed by BBC Research and Development. It is the most well-known of all the BBC loudspeakers, and remains the compact loudspeaker of choice for many today.
As the only company to have ever manufactured the LS3/5, and now also the LS3/5A, audiophiles are now in the unique position of being able to hear for themselves the differences that these changes made to the design originally intended by BBC R&D.
