Russell K Red 100 Precision Audio Loudspeaker System

The Red 100 was the first loudspeaker designed by Russel K. and has since then won the hears of many HiFi reviewers and customers.

Alan Sicrom of Hifi+ puts it like this: “I think the reason the Red 100 works so well is it combines the twin demands of both timbre and tempo exquisitely, highly recommended.”
