Here's my current project, a 3-way tall loudspeaker using ScanSpeak (double woofer 22W Discovery, medium 15M Discovery and tweeter 602010 Illuminator), amplificator Ram Audio T2408, active filtering on a HTPC using an E-MU 1820m soundcard.
Here's a 3D render, using Blender software www.blender.org :
I'm used to 3D for other purposes and using it for loudspeakers allow me to create blueprints to be used in my workshop :
Here are the drivers :
Each enclosure is made of 23 panels, here are some picture of the first test assembly. Front panel and inner frames still need to be hollowed out, obviously.
Some detail on the adjustement of the panels : eache one must be cut at a different angle, to be able to assemble them. So 3D modeling is extremely useful to get accurate dimensions, which I draw on the panel to cut the angle using a belt sander.

An externally hosted image should be here but it was not working when we last tested it.

Whatever you're scaling the pictures with looks awful- can you go with bigger pics and remove any effects you're adding? Looks like a nice faceted build, pretty cool stuff.
Thanks for noticing the issue, I didn't try to click the thumbnails. I didn't add any effect, it was just a terribly wrong shrinking. I fixed it and inserted larger images, let me know if there is any further issue.
Two very handy programs to scale photos :

The preview came from the image host (casimages.com), not from me : I didn't do any image rescale. I guess their BB code wasn't correct for this forum (it was fine on HCFR).
Everything looks clean now, at least for me. Can anyone confirm it or explain any further issue ?

Looks much better- thanks! The other ones were giving me a brain pain. Nice design, I always liked the "stealth fighter" faceted cabinet look. I'll be interested to see what you think of the small-flange dome tweeter- I'm surprised we don't see more use of them, they seem to be high-performance units.
That looks great the 15M from the discovery range has always been one I've been interested in. It would be great if you could make some detailed measurements of it.🙂
Hello,
Here're an update after some more hours this week-end : I sanded some angles on some pieces to do a test assembly.
You can see the current state of the build on the first 3 pictures. On this side of the enclosure, I need one more triangle at the bottom, and 3 other ones on the upper end. And the top, going from front to rear end using a 4 cm wide piece.
The next two pictures show the inside : you can see the gaps between not-so-well-adjusted parts 🙂 I obviously need to fill them with resin or wood glue.
Some frames are missing (the medium enclosure) and they still need to be hollowed.
I guess you noticed it requires masking tape to hold it in place. Completely not suitable for gluing, so I used some small metal squares. Maybe not enough for white gluing it so I will try neoprene glue.
The last two pictures show the enclosure in the listening room, standing along with my current setup : DIY bookshelves and a W12 GTi subwoofer. Looks like the right size, like a friend of mine said 🙂

Last but not least, I now see the downside of handcrafting all the pieces : here is a 1mm-wide gap between the same two panels.
I'm glad it's only at the top of the panels (first pic), it's far less visible at the bottom(second pic). I will fill the gap with wood filler or glue.

Very nice design !
Things get more difficult as soon as you step away from the rectangular box 🙂

onni, thanks ! I'll, but first I need time to work on something worth showing 😉
danny_66, indeed ! But I wanted something much more decorative, so I guess I had no other choice.
