True. One day the will make an electrostatic horn loaded speaker that can get to 140db!

Don't put a horn anywhere near my electrostats.

I know you were just "making a joke", but "putting a horn" on it is something that is misunderstood by many people.

A horn is actually a bandpass type device.  It has limits on the top end (due to the size of the entry into the horn), and the low end (due to the length, expansion rate, mouth size etc).

In reality you need different expansion rates for different parts of the freq spectrum.  Hence the reason a simple horn on a full range single loudspeaker does not work as well as it should.

The higher freq need a faster expansion rate than lower freq.  Mids are in the middle ;)

It is the "proper useage" of horns that make them actually work.

Size matters (both large AND small)-in all kinds of ways with horns.

In order to get get gain up high-the entrance into the horn has to be small-hence the reason you don't get much gain up high from a 2" compression driver.  A 1" into a horn will actually have more horn gain in the top octave or so.  And since it already has a greater output (due to higher sensitivity and lower mass) it can actually produce MORE SPL than a 2" driver-at the higher freq.  Down lower in freq it is a different story.

Everything is about tradeoffs-so it is important to understand what is going on-so the proper tradeoffs can be made and determine what is most important for a particular situation/usage.

I was of course kidding.

Hey maybe  plasma speakers will be practical one day!

I always wanted to build a plasma speaker.

I wanted to build one with my son before he graduated HS-but never got  around to it.

On of the big problems with plasma (beside ozone depletion) is they have a limiter output capability.

But I STILL think it would be cool to have one.

Maybe some day when I get a few (yeah right) hours of time----------  I guess that would be about 3 days after I am dead.

I have been researching low mass and massless speakers more lately. The concept intrigues me. Ultrasonics and hyperdirectional designs should be explored more.

Can we get them to do double duty as smoke eaters?

Nomex« and Kevlar« laminate speaker enclosures.  The "horn" version could be a flame thrower....
