You guys ever get into electrostats or magnetic ribbon speakers ? Their high end can be breath-taking at times. They're definitely not for the "loud and proud" crowd, but in the right room can be impressive. I had a set of Magnepan Tympani's about 20 years ago and wish I would have kept them. I bought them used for about a grand, but think they cost 3 or 4 times that when new. There were 3 hinged panels per side and by adjusting the contour of the panels, and depending on placement in the room, you could change their sound. There was no "box" per se. Each panel was something like 6' tall, 22" wide and about 2" thick. This is one of the few photos I could find on the internet:
They took a TON of power to get going and were better suited to use for listening to movie soundtracks, or jazz or classical music. Here's another
shot I found but did not have the 3 panels per side:
Just picked up this oriental room divider made out of carved sea-shells and it reminded me of the Maggies.
Maybe I'll look for another pair............
