We've talked about Zu Audio before. Sensitive yes, but measures like a 2 yr old scribbled on some paper:

Plus, I'm instantly skeptical of any speaker maker that says stuff like this:
Omen Center loudspeaker now get 200 hours of factory burn-in, it will sound good right out of
the box but will not give you its best for several weeks, depending on how much play it get and
what kind of music it sees. If at first you find it restrained and a bit conservative, relax, it will
come around.
Zu Omen Center loudspeaker is sensitive to the cold. If you have received, moved or stored it in
cold temperatures it will take a week or so to again sound its best.
