Default Cabinet in layers

Saw this image in another thread. That looks like a cool way to build a speakers in layers like that. If you didn't have a lot of precise tools, it might actually be easy to build one template and then use a router to but the final shape of each strip.

Anyone know of any plans online for an enclosure like that?

I believe this is actually done with a CNC machine

It can be done with a cnc router or mill, if you have one (or put the 'ware on your existing machine), and have the 'ware to generate the cut.  In hobby and small-shop practice, it's more often done with a router pattern, or even a jigsaw and a little elbow grease.

I object to it because, unless we are very clever with design and layout, it's extremely profligate of material; our waste pile is going to be twice the size of our piece pile.  That said, it is one of the very few practical ways of getting certain shapes, like horns, without a great deal of time and skill.

I like kerf bending for a lot of this sort of work myself, but that method is not without it's shortcomings as well.

Aloha,

Poinz

search on translam or layertoning (the last a word i coined after Tony's moniker which as of the latest aXP (IIRC) is now officially part of the lexicon).

You can see examples of Tony's brilliant work on the Full range forum, and Andy Graddon has a part of his site dedicated to boxes that aren't monkey coffins -- a number of those translam construction.

dave

PS: i have the same objection as poinz... and if not done in a considered fashion you can end up with a box that doesn't have as good a sonic signature as a box made the old fashioned way.

Why would you have a total flat reflector directly behind the driver?

And again, the aspect ratio of the mouth really need correction for proper wave launch.

I think someone made a frugal horn in that method, I had it for my wallpaper for a while.
It's not for the faint-hearted KVK, it takes a lot of wood and work and it's going to be damn heavy.
Personally I love the look of it and a set of curvy changs in plywood made like that would be glorious. I don't trust myself not to change my mind about what cabinets I want so I'm not game to start.

Nice design - could be fun to build a pair like this just wonder why the designer have made this combination of nice curves and sharp edges ?

This would be the ultimate way to make it. However, it is also the ultimate requirement for materials, since there is so much wastage. Don't know how may sheets of MDF you will need, but it will be a goodly number, IMO.

These would clearly be very wasteful if each slice was a full profile, but don't I see joint lines in the picture that indicate the slices are built up from smaller pieces? With a good layout, I'd think a CNC could cut that all out pretty efficiently. I don't think I'd try it with a router and template.
