CNC machines and modern speakers

[Poultrygeist]

Speaker enclosures of today are cut by CNC machines.

This guy has his own and they're getting more and more affordable ( under a grand in some cases ).

If you have access to a CNC router you can program in the dimensions and get an instant flat pack. With some glue and clamps you're in business.

Most cabinet shops of any size have a CNC machine. Supply the wood and any of them could cut your speakers for a nominal charge.

Here's an industrial CNC cutting a line array.

How easy it would be to take these horn plans to your local cabinet shop and have them CNC'ed. You'd have audiophile class speakers for around $200.

Judging from the replys am I the only one who finds this interesting? :sigh:

Oh well here's one more CNC in action cutting Zu speakers.

Very cool. My wife is involved with a lot of "maker" stuff and has access to these types of machines. I may well have a project to do this summer

CNC (and routing in general) is cool stuff.

Look at diyaudio.com, under the name shinobiwan.

I've bought a few cabinet flatpacks that were cut with CNC machines. Definitely the wave of the future. :yes:

I ran CNC Mills, Lathes, Lasers, Wire EDMs for 20 years. It is very fascinating to know and see how things are made.

I read somewhere that you can buy a small garage version for under a grand.

Wish I had a garage

 

[marqueemoon]

I wish my garage wasn't quite so full of bikes. Ok, not really.

I'm a little surprised this doesn't happen more on an on demand basis.

Here's a CNC'ed flat pack assembly.

The sub enclosure flat packs I've bought from Parts Express are much the same.

Anyone can build great speakers and save tons of money with flat packs. Eight clamps from Harbor Freight and some wood glue and you're good to go.

Pre cut flat packs are a great choice for full range single driver speakers.

Not having a crossover to deal with makes for an easy assembly. The drivers in most cases are just wired directly to the speaker binding posts. Some require damping material while others don't.

The Bob Brines website gives a good explanation of single driver speakers and offers flat packs for sale.

If anyone's interested, I uploaded a video of my CNC router cutting a pair of my older speakers a while back. I'll link the video but please be aware that the audio is SUPER loud, so adjust your volume down before clicking. https://www.youtube.com/watch?v=KXe8WVix4zA

Steven,

I'm envious.

Paul you shoulda been a cabinet maker

Paul you shoulda been a cabinet maker

I actually took a weekend course in cabinet making at a local woodworking store. I really enjoyed it and learned how to do joinery with the Kreg pocket hole jig. Even though we built kitchen cabinets the tools and construction were much the same as for audio.
