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 isn’t an issue.
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.
