About the LS5/8 BBC Spec
The Graham Audio LS5/8 is a passive, two-way, front-ported loudspeaker developed from the BBC monitor design. Originally conceived as an active speaker, it uses a passive crossover designed by Derek Hughes that improves resolution and imaging while conforming to the BBC specification. Its 300mm Diaphnatone polypropylene bass/midrange driver and Audax HD 13D34H tweeter deliver a 40Hz–16kHz response (±3dB), 89dB sensitivity, and output exceeding 110dB for a pair at 2m, making it well suited to larger rooms and high listening levels.
