A flagship BBC classic is reborn!
Graham Audio LS5/8 Monitor Loudspeaker
Designed in conjunction with Derek Hughes and Volt loudspeakers the high resolution two way passive loudspeaker features a bespoke
12 inch bass/mid unit and legendary Audax tweeter matched to a handcrafted crossover, constructed by Derek Hughes to exacting standards.
The project was conceived to reintroduce the famous BBC design as part of the Heritage Series spearheaded by the Graham Audio LS5/9 monitor speaker that has received such worldwide acclaim.
The design principle was to maintain the high class midrange and balance of the LS5/9s but with greater extension, power handling and authority. The same continuity of sound is available between the models and engineers can swap between the two different speakers with confidence during recording and mastering.
The LS5/8 was originally issued as an 'active version' by the BBC using an in-house modified crossover card fitted to the vintage Quad 405 amplifier which bi-amped the speaker. Derek Hughes masterful passive crossover design greatly improves on the resolution and imaging of the original speakers. The bespoke 12 inch bass unit made for Graham Audio is a custom device that perfectly matches the Audax HF unit and the tonal balance and natural sound of the speakers is greatly improved over the original design, whilst still being typically British in nature and conforming to the legacy of the demanding BBC license specifications.
