Sound of Zu Soul Superfly vs Zu Druid Speakers

While not hearing the souls I have updated my Druids with Soul drivers and hi pass, also adding griewe loading and internal damping. The only difference is a slight volume decrease compared to soul now.

My Druids were mk4/08 and there is a difference.

Druids were warmer before.......... now they have better bass and attack. The Mundorf hi pass provides clean detailed treble but is still smooth which is nicer than the old Kimber based hi pass.

Zu has a BIG SALE this Thanksgiving weekend, by the way.

I did forget to mention the increase in bass performance with the Zu Souls. I appears my comments and the most recent post sum up in simple straight forward language the basic changes noted with the Zu Soul Superfly vs the Zu Druids.

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.
