Default Bookshelf/Desktop ESL's

What is the reason that you don't see any small ESL speakers? Is there a mechanical drawback? Diminishing returns in quality as size decreases? I was looking for a small ESL project to get some hands on experience in order to get a better understanding of the process. Not even looking for something that really sounds great, just something that is small and works.

I was looking at those, $450 Aussie. I am sure they sound great but out of my curiosity price zone. I am finding more threads the more I look and all searches seem to bring me back here.

I just recently completed a set of small panels 12" x 12" to get my feet wet in the ESL realm. They would make fine bookshelf speakers, but certainly need a subwoofer (2.1 type of system). They do not offer room-filling sound levels, but are quite satisfactory for a small room. I'm using them in my office and they do quite well.

Yah I read your thread and those are very close to something I would like to try. I am really into using cigar boxes for projects and surely have a couple matching boxes around the same square inches I could use for frames. 2.1 for sure if I can actually get some decent sound from the pair. Will reread your thread again. Hope your upgrades turn out well. Thanks for reply.

P.S. Gee Sy, this is a real groovy apartment you've got here...

All I ever build are Desktop ESL's !!
I am surprised you haven't seen them yet !!!

I may be the only one whom has ever done this.
I made my first ESL's as shown in the pictures in 2003.
Here are some of the links to my builds,

A Desktop ESL Build

A Segmented Stator Desktop ESL

The two systems I have shown in the first link can be found in many of the threads here at DIYAudio.

Enjoy !!

Hi,

I started my experiments with small panels some years ago.
After I heard them became not statisfied with bass and mid range output.
So next experiments came out larger and larger.What I built at last can cover down to 85 hz or even less but at reduced output.
A small panel can be made to sound well, but you will need to make a hybrid speaker with a cone bass driver and ESL, crossed over lets say between 400 and 1kHz depending on its size.
Building a line source element(lets say, 10x100 cm) would yield good vertical dispersion pattern and acceptable horizontal even from a flat perforated sheet.
A square element with the same area would have somewhat more low end extension but would be extremely directional.

Good luck.
Lukas.

Excellent and thanks for the links. Heading that way to browse now. At this point I would be happy building ESL tweeters! Just want to "do it" before I "DO IT". If they sound well (which would be a bonus to actually just working) I will pair them with a small sub.

i was wondering if there was enough interest to create of the shelf panels. with Pcb as stator material. with slots or drilled holes.

i might get me a plate of 1 mm thick 51 cm x 115 and cut some prototypes. in like 10 x 25 cm panels ? for mid and high frequency's ? with some support dots for the foil they could reach down to 300 hz with some efficiency to.
