Here's what my friend who reads japanese said of the speakers:
There is no price quoted on this. What's interesting is that it says you should only use an amp between 50 and 100 watts, because more than that could be dangerous. The top part says that the woofer, midrange, tweeter are all condenser units for reproduction of the most delicate nuances of sound. It comes with spikes, a dedicated power cord, and dedicated cabling. The thing weighs 170 pounds each (!!). At the bottom, it says where in Tokyo and Osaka you can see the speakers demo'd. On the bottom, there's also (I think) a streaming video commercial for the speaker. haven't tried it yet (just printed the page out).
