Which SPEAKER for the 21ST century?

After a quick trip around the web, I found only tweeters using the plasma technology. Mfrs. include Accapella, Magnat, Corona, and a DIY page for a plasma tweeter by Ulrich Hauptmann in Holland. They all use a flame/ionization technique which results in an AM sound transmission. Commonly, a horn is coupled to increase sensitivity. Primarily used for 4kHz and above. Tube electronics are used to regulate/modulate the flame. Advantages are stated to be coherence, imaging, natural tonality. The only price I could find was the Accapella Horn Loaded Plasma Tweeter at $2600 each. Sounds like a really neat technology to me, but possibly a little dangerous. I guess we'd have to start up a new thread about whether we would then need pure-silver litz braided propane gas lines for the tweeter.

As a good listening room does not allow for balanced distribution of sound from multi channel direct, bi or di radiating speakers. I believe that single omni-directional drivers with digital room correction will permit suround sound to actually work.

thanks alot for the web address...to me this manger looks like a partial answer in an attempt to match at least some of the SOUND LABS highly praised qualities...of course on a much smaller scale ..which suits me fine ..cause i do not want to be overwhelmed by any speaker ...no i prefer dynamics over a big sound stage...yes i know this goes against the likes of the majority... every time i go to an audio club meeting the volume is way over the level i prefer
