I know this disappeared for a while, but it is now back up.

Hope people find it a help with ideas.

Wonderful speakers! The TL looks like it has a digestive system...
I made a pair of 16" diameter spheres with layers of 3/4" MDF (for a coaxial Seas P17REX COAX/F) using this method, but I took advantage of the opportunity to leave lots of diffracting/reflecting edges on the inside, similar to Seventh Veil. And my front baffle intersected perfectly tangential to the driver.
Seems a shame not to curve the baffle while you're at it to fully exploit this technique. But I guess I have to say something critical about everything...

Where can one get that kind of work done? How much does it cost?

Andersonix · 28th January 2005, 10:54 PM

Pics? You talkin' to me?!

Joules, with a jigsaw or router, you could create your own mountains of sawdust. Cost? Why is it always about cost? How much TIME is the real question....

Building stuff is fun, but it's just a box. I don't want to spend a huge amout of time or money just to build a box. I thought about hand cuting pieces as suggested, but only if there are no better alternatves. If the pieces could be laser cut for a reasnoble price, that might be the way to go. I contacted one laser cuting company and sent them a drawing of the pieces for a simple box 24 x 9 x 17 inches. and they wanted $500 to cut out the 26 pieces. This is to much for a simple box. This was not a complicated box I just wanted to get a feel for how much the process costs. Anything more complicated would have cost even more. I can build a very nice box using more normal processes for alot less $ and time. If there is a company that can do laser cuting as showen in the previously posted pic's for a more reasnoble price, I would be interested.

Joules, you could also enquire about local workshops with a CNC router. If it is still too expensive, a jig for a router that would cut out the pieces identically.

You could build it to use the template rings that are often supplied with routers (and can be brought aftermarket) and have a preset sized bit of square mdf slided underneath.
