Description
A development of the famous BBC LS5/9, the LS5/9f is the perfect choice for those who prefer floor standing loudspeakers over the traditional stand-mount form factor.
However, the changes aren’t simply cosmetic. Yes, this model uses the same handmade bass/midrange driver from Volt along with the 34mm Audax tweeter as the regular LS5/9, both selected to the same tight tolerances. But the larger cabinet allows for increased bass extension and greater dynamic range.
Based on positive feedback from customers and Graham Audio’s dealer and distribution network, they have replaced the soldered connections for tweeter level calibration with the discrete switch first seen in the LS6, which allows for subtle adjustment of the high frequency level. This is useful to help overcome difficulties presented by some acoustic environments, especially those with a lot of absorbent furnishings and finishes.
The cabinet follows established BBC “thinwall” construction practise, and includes the integrated plinth with flow-optimised port first seen in the LS6f. As usual, the grille is held in place using hidden magnets. A range of hand selected real wood veneers is available.
