About the LS5/8S
The Graham Audio LS5/8S is a BBC-licensed, two-way passive reflex monitor loudspeaker and the slotted-port variant of the LS5/8. It uses a thin-wall, critically damped birch-plywood cabinet, a custom 300 mm Diaphnatone polypropylene bass/midrange driver, and a 34 mm Seas soft-dome tweeter. Designed for high sound-pressure levels and larger listening rooms, it has a nominal 8-ohm impedance, 89 dB sensitivity, and a frequency response of approximately 40 Hz–18 kHz (±3 dB). The LS5/8S is a standmount monitor, not a floorstanding speaker.
