Description The Graham Audio LS5/9 is a high quality licensed reproduction of the original LS5/9 monitor that was designed by the BBC’s research and development department. The Graham Audio LS5/9 standmount speakers feature a brand new 8″ bass / midrange drive unit that was developed entirely in-house and constructed using the best materials available at the time. The LS5/9 is a close sonic match for the much larger LS5/8 monitors, but optimised for use in smaller studios and control rooms. Equally at home in a domestic setting, the open and expansive midrange reveals previously unheard details from even the most familiar recordings. 8″ Woofer and 34mm Tweeter With Derek Hughes at the drawing board, the original BBC design has been recreated. A new bass / midrange driver has been developed in conjunction with Volt Loudspeakers. This new driver uses a substantial die cast aluminium frame and a massive motor assembly, with a diaphragm formed from a carefully selected grade of polypropylene and matched to a high quality rubber surround. Each driver is hand assembled and tested by Volt. The tweeter is a selected version of the Audax 34 mm soft dome, which is protected by a strong metal grille. A sophisticated crossover network blends the two drivers together and equalises the overall response, for optimum performance. Classic BBC “thin wall” cabinet design The cabinet uses classic BBC “thin wall” construction, and is manufactured in the UK from high quality 9 mm birch plywood. Hand matched veneers are applied and finished to a very high standard. All joints in the cabinet are reinforced with hardwood batons, to ensure long life and total air sealing. The panels are mass loaded, to ensure that resonances are moved away from the critical midrange region. A layer of Rockwool, held in place by fabric, provides air damping. The grille is machined from a single piece of 9 mm birch plywood and is held in place by concealed rare earth magnets.
