Description
GRAHAM AUDIO LS5/8 STANDMOUNT SPEAKER
The LS5/8 is the BBC’s flagship design, and was developed because of the need for higher sound pressure levels and greater transparency and consistency than the ageing LS5/5 offered. This was the first BBC loudspeaker to use a polypropylene diaphragm which, being lighter than Bextrene, offered greater efficiency and lower colouration. A carefully researched cone profile enables the unit to work successfully well into the midrange.
After many months of intensive development, the Graham Audio LS5/8 refines the concept further. Designed in conjunction with Derek Hughes and Volt Loudspeakers and manufactured under license in the UK, it features a unique 12 inch bass/mid unit that is married to the same 34mm Audax tweeter that is used in the LS5/9.
As with all our BBC monitors, the cabinet is a finely tuned structure that uses high quality birch plywood and hardwood batons. The 12mm panels are mass-loaded to move resonances away from the midrange region and Rockwool is used in preference to cheap foam for air damping.
