Cannot verify for spellings as I copied from above responses.
Let me know If I have missed any.

I wldn't call Zu obscure! Anyway another one would be Audio Machina's Pur System....I wish I coud audition them. They are very interesting indeed.

Zhorns another ;)

I would add Hawthorne Audio. Haven't heard them myself, but an interesting design of drivers for open baffle implementation. They have their own friendly and informative forum and first rate customer service.

Another brand I found at the UK HiFi show in london last weekend, Acoustic Plan.

A very nice open baffle design, with base drivers that can be driven actively or passively. That gives a sensitivity of 98 driven active and 88 passive. They really sounded very good, open, transparent, good soundstaging. I always think if a sytem sounds good in show conditions, it must really be good.
