Default Trapezoidal ESL Drivers

I was wondering if anyone could confirm my theory that a Trapezoidal ESL Driver would be able to handle higher frequencies better then a rectangular driver and still be able to produce low ranges to about 350 Hz well while remaining under 8 inches in width.

No, horizontal dispersion of high frequencies will change along its length. The narrow upper parts will disperse more than the bottom. I don't think that you want this kind of dispersion.
Bass can be improved and that's the reason to build such structure.

Yes, I can see how this might become an issue. My main reason for this is that I am trying to stay as small width wise as possible. I plan to handle the bass with a separate dynamic driver, so bass really isnít an issue.

Narrow and high drivers reproduce high frequencies better, if they are positioned in the level of ears. But bass reproduction is even worse then...

Yes, thats why I was thinking that a trapazoid shaped driver would work for this. it would only be a small increase from the width of the top to the width of the base.

I think that there will be not much difference between rectangular and trapezoid driver.
I have seen an interesting sketches of round bipolar enclosures to use with ESL... I don't know if it works well.
