GRAHAM AUDIO LS5/9 BOOKSHELF SPEAKER
The LS5/9 is a high quality studio monitor that was designed by BBC Research and Development and featured a brand new 8 inch bass/midrange drive unit that was developed entirely in-house and constructed using the best materials available at the time.
Designed for use by the BBC in smaller studios and control rooms, the LS5/9 is a close sonic match for the larger LS5/8. Equally at home in a domestic setting, the open and expansive mid-range reveals previously unheard details from even the most familiar recordings.
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 which uses a substantial die-cast aluminium frame and a massive motor assembly, allied to a diaphragm formed from a selected grade of polypropylene and matched to a high quality rubber surround. Each bass driver is hand-assembled and tested by Volt.
