The new Graham LS8/1, designed by Derek Hughes. The Graham LS8/1 resembles daddy Spencer Hughes's fabled two-tweeter BC1 (footnote 2). Compared to the original, two-tweeter BC1, which extended up to 16kHz, the Graham LS8/1's new "super-tweeter" extends up to 20kHz. At the other end of the frequency spectrum, the Graham LS8/1's woofer descends to 45Hz ±3dB. O'Hanlon says that the speaker's in-room bass remains audible down to 32Hz.
The Graham LS8/1 arrives in the 50th-anniversary year of Spencer Hughes's BC1 and comes equipped with many of the same 21st century materials that distinguish the Graham LS5/5 from the BBC original. The Graham LS8/1 sports an addition to Spencer Hughes's original design: a front panel switch that allows adjustment of the tweeter by +1 or +2dB. Although only 100 signed-and-numbered pairs have been produced, some remain. Future production runs of the Graham LS8/1 will include veneered front grilles but will not be signed, numbered, nor supplied with stands.
