S/S Discovery 18W 8424G00 Diameter:180mm

Fibreglass Cone Mid/Bass

The Discovery series is designed for the discerning audiophile and to meet the needs of this demanding audience, Scanspeak have developed several new technologies to help reduce distortion and damping within the speaker.

Built onto a rigid cast Aluminium chassis, the coated fibreglass cone reduces vibration and standing waves, whilst the vented motor system minimises compression, resulting in a very open and dynamic sound.
