I met the Zu guys at the CAS 2013 show and asked them about the Druids and Soul Supremes. He said(Sean?) that they are exactly the same speaker, but with a different build style. The Druids cost more b/c of the fancy aluminum bottom plates. I'm not sure if the plates change the sound, but he said they really didn't. He suggested that if I wanted more bass extension, to get the Supremes and add the Zu $2000 subwoofer. (BTW, they had the Zu Submission in their audio room, and it's the best sub I have ever heard, but will run you $4k.)
