They certainly look interesting! Quite how they would sound I can not imagine  (either good or bad). Why, you could have an entire Japanese style house where all the internal walls are really speakers! The sound can then follow you around the house and even track what direction you are facing.

okay okay...

If you have £10k to spend then how about these MEG RL901k (£8k) - http://www.me-geithain.de/index2.html?eng Can't seem to do a direct link, go to products, studio monitors, RL901k.

and a Velodyne DD-12 (£2k) - http://www.velodyne.com/velodyne/products/product.aspx?ID=4&sid=431k716i

The MEG RL901K is an absolutely awesome monitor. It is the most accurate commercial system I know of; featuring concentric wave-front (co-axial drivers), pretty much time aligned and what is essentially a U frame open baffle for bass and even a cardioid bass radiation pattern to reduce room interaction. It goes to 35Hz so it would be a very easy thing to pop in the DD-12 sub to take that down to 17Hz.
