Graham Audio LS5/8S Monitor Loudspeaker
Graham LS5/8S is a premium two-way monitor loudspeaker that refines the iconic BBC LS5/8 design for high-end home audio environments. It features a slot-loaded 300mm Diaphnatone bass driver for smoother off-axis response and a SEAS 34mm soft dome tweeter—upgraded from the original Audax—for improved clarity and integration just above the crossover.
Housed in a thin-wall, critically damped birch plywood enclosure and finished in real wood veneer, the LS5/8S maintains the natural, uncoloured sound of its predecessor while introducing greater transparency, spatial coherence, and tonal balance—especially in typical living rooms. With 89dB sensitivity, 8Ω impedance, and compatibility with amplifiers from 50 to 250 watts, it delivers effortless dynamics and wideband accuracy at both low and high volumes. Stand not included.
Finish options such as teak or custom spray available upon request. Lead times vary based on finish selection.
