Sound of Zu Soul Superfly vs Zu Druid Speakers

Hi,
I have Druids that have been updated with the newer drivers offered a few years back. At the time, I installed the Mundorf caps and Duelund resistors.
You mention that you added "Griewe loading and internal damping". Can you tell me how you accomplished the Griewe loading?

Sean suggested to add a foam wedge with a 3/8" gap all around the base of the Druid. I stuck the wedge to the mesh that covers the hole in the base. The wedge should be tapered on all sides to a point in the middle of the speaker level with the center of the tweeter. Zu use a closed cell foam but I chose an open cell melamine foam so not to affect the cabinet volume. He also said to glue a 1" dowel between the FRD and tweeter and the back of the speaker box. The internal damping I used is the same as Zu use on the Superfly, it's a waterbased damping paint, I applied 2 coats, about 1/8" thick. Simple tweaks but a bit ddly, especially cutting the foam.

As I used the new HO FRD from the Superflys I had to add a 10 ohm Duelund resistor insted of the 12ohm of the Druid.

Hope this helps

Can't speak for the Superfly which should only be better, but two of my friends bought the Zu Omens on my recommendation, and one happily replaced her Dali floorstanders with Zu Omens, and another replaced his Vandersteens with the Zu Omens. He told another person here in Tucson about the Omens, and he happily replaced his expensive Sonus Fabers with the Zu Omens. I am still happily using my Zu Druids and am keeping them since I had them painted piano black and put granite bases on them.

I had opportunity to listen to my Zu Druids alongside some Zu Omen Speakers that had not been broken in yet. At this premature comparison, I found the Omens to have a presentation that is in a slightly clearer and slightly less euphonic direction than the Zu Druids. The Omens are still warm, and have a little more bass presentation, yet their tonal picture seemed to be a little less warm and more airy than the slightly more 'tubey' sounding druids.

In all fairness, much of this may go out the window as the Omen's break in and the gap closes as the Omen's warm up. However, I suspect much of the difference however small it is, will remain.
