Back to the Zu's.
The way these Omens are set up is not what the company recommended.
Zu recommends raising the bottom finger ports just high enough from the floor to slide a CD case underneath and their short standard spikes hardly allow for any more.
Bottom ported speakers can be a pita but after much trial and error the Omens improved greatly by creating more breathing space for those finger ports. I used longer lag bolts than the stock spikes to gain distance from the floor which opened up the sound. Using slightly shorter lag bolts in the rear aimed the tweeter at the ear rather than at the belt buckle. Using a ribbed mat underneath also helped.
If I had only listened to the Zu's plopped down in a hotel meeting room I probably would have passed on them. This is one speaker that requires great care in set up but more importantly it takes living with a pair before they can be fully appreciated for what they are.
I believe that may be one reason for such polar opposite opinions. Casual or one time listeners seem to have negative opinions while owners with long term exposure are far more likely to embrace them.
It takes time for one's ears to adjust to what wide band speakers do so well.
