Zu Audio Druid mk. 2 loudspeakers

With 101 dB efficiency and 11-ohm impedance, the Druids can be mated to flea-powered SETs and high-powered monoblocks equally. Using a full range driver mated to a super-tweeter, the Zus were extended in the bass and very dynamic. While they require careful set-up to sound their best (which includes Zu speaker cables), these Druids were “one of the most enjoyable speakers” we’ve heard.
