Graham Audio / Chartwell LS6F

The LS6/f uses the same custom drive units as the stand-mount LS6 and has an optimised crossover network using premium quality components to integrate the acoustic output from both drive units and equalise the overall response for optimum performance in free space. A switch on the front panel adds 1 or 2dB to the tweeter level, which might be advantageous in certain acoustic environments.

 In common with all our loudspeakers, the cabinet uses the classic BBC "thinwall" construction, where the panels are mass-loaded to ensure that resonances are moved away from the critical mid-range region, and a layer of Rockwool is held in place by fabric to provide air damping. Hand-matched veneers are applied and finished to a very high standard. The grille is carefully designed to minimise diffraction effects and is held in place by concealed rare-earth magnets.
