I've been lurking around diyAudio for nearly a year trying to absorb some information about speaker building. I finally worked up the nerve to stop reading and just start building! Here are the results. The first set was based on Zaphs tangbands and the second were kind of a combination of several thoughts/speakers..... If you regularly post on this site, thanks again, lots of good info for us "newbs".

Nice work!
Nice work. those curved cabinettes lookes great!
I,m buiding about the same thing, but i use the Hi Vi 3" design from Zaph.
Also curved shaped like your.. slightly bigger and they are proberly going to be veneered with Jacaranda.
I only have 2 pictures so far, and my skills in Photo are not very good.. but here they are.
I used antoher approch to getting it curved.. as you can see from the images..

LOOKS GREAT !
I love those TB w3-871s units, I made myself a 5.0 HT set .
(see somewhere else on this great forum)
But can You tell me how You greated the filter for Your mains ?
I like to try also with two TB's in one cabinet.
You´d have to roll one of the drivers off to avoid high frequency lobing.But can You tell me how You greated the filter for Your mains ?
Jim Griffin did it different to CSS; see graphic.
Can´t remember from whom I got it so no guarantees.
An externally hosted image should be here but it was not working when we last tested it.

"Nice work! Please let me in on the secret of how to determine the internal volume of a curved box. I want to do some ProAc 2.5 clones with a curved box."
No secrets really. I used Microsoft Excel to determine the x,y coordinates for 1/2 the cross-section (looking down on the speaker) and then used the trapazoidal rule to estimate the area under the curve. I would also venture to guess that some of the free CAD software out on the net might also do this except easier?...maybe Turbo-Cad? I'm not sure though....
But can You tell me how You greated the filter for Your mains ?
Jens was on top of it. I found the same filter info he posted on this forum and I chose to use the CSS version
That's fantastic work Stuart ! What method did you use to attach the veneer?
Thank you again for the kind words! I used contact cement and a whole lotta patience....

Hi, Dirk
I just finished designing one in Autocad. I'd be glad to help.

Most 3D CAD software can do it easily. Like the one that was given for free, Alibre I believe can calculate it.
