>>>The major problem I had with the Omen Defs was the high frequencies which I thought was related to the tweeter. However with the same tweeter in the Def iii's, this problem is completely gone and everything sounds better. I think it must be that the improvement is from the new Nano Drivers.....detail, top end air, staging, imaging, etc. are all world class........<<<
It's not just drivers. Quite a lot of the upper midrange and treble glare on Omen Def that also blurs detail a bit is coming from the comparatively excitable cabinet. In the Def2, Def3 and Def4 cabinets, you get to hear the drivers much closer to their intrinsic performance than in the lower end Zu speakers. This isn't a knock on the less expensive Zu speakers but instead is intended to spotlight the cabinet as elemental to Definition's overall sound. If it were only drivers and internals, then Omen Defs could sound much closer to Definitions than they do.
The cabinet and baffle engineering and build decisions in the upper end Zu speakers are often overlooked but they are hugely influential to the improvements you are hearing when moving up from the simpler cabs.
