B&W Nautilus evolved into Vivid Audio Giya G1. Both engineered by Laurence Dickie. Vivid Giya G1, 2, 3 and now 4 use identical techniques to Nautilus with vastly superior drivers and motor systems as well as increased power handling, and reaction cancelling bass drivers. The Vivid doesn’t require 4 separate amplifiers anymore and will run off a 15 watt class A tube amp to a 1000 watt beast. Sensitivity at 92 db/watt. Photos © Jake Purches.
