Default The end of speakers?

Just like the electric car saw off the combustion engine!

OK, and what a resonance frequency of thin film? 1khz?
It would works only at low volume, maybe headphones.

Default Bulky speakers

I may be out of order here but I like cabinets, especially those with real wood veneer. To my mind they are a part of the lounge furniture, very much in the vein of the bureau or coffee table. The aesthetic quality of this new invention is very low indeed, but maybe I am old fashioned?

Who needs CNT when you can have the best sounding speaker ever with a plasma ball?

hillplasmatronics.com

Full range point source with (almost) zero diaphragm mass. Very fast transients and exceptional clarity.

Hi,

Though I doubt the output capability of such a device
the interesting aspect is its a bipolar, not dipolar device.
As such the diaphragm frequency does not matter.

Further analysis indicates you'd have to run it with bias,
at half maximum temperature for symmetrical drive.

rgds, sreten.
