Your work's always a pleasure to see, Paul.  Very original and well thought out, I love it!

Paul,

That is some amazing work and your skills really are breathtaking.  I cannot wait to see the finished speakers.

Hi Paul,

very cool! Take a lot of pictures, please! They look already so cool I might even leave them as is for the looks - a bit of steam punk style?

Thanks everyone, I guess Ill keep on going then.

Someone suggested flame painting, much harder than it looks. http://makezine.com/2015/09/02/painting-on-copper-with-fire/

My very bad attempt, might go with it any how......not ready to do butterflies yet.



Started pouring epoxy resin over the fins before I install them to smooth over any blemishes.



The horn drivers turned up yesterday.




Started thinking about the cabinet.
This is a very bad drawing of the basic out line.
Will be MDF with taped sided, will kurf the corners, so I can make the top, sides and bottom from one piece (hopefully) and rebate all the joints.
The top and bottom crossed out sections will be filled with sand (hope the floor boards handle the weight.)
And I'll brace behind the driver.
Will be using 7mmX 70mm Merbau slats glued to the cabinet as a veneer.
Not sure about the finished face yet, be something similar to old radios, but different.

Thats sorta what is running around in my head, may change before I start.....feel free to tell me if can do it better.

Hello, just an up date.

Installed the faitalpro onto the horn, and they make sound.



The 12" eminence woofers turned up they are very big.

 

a minindsp measuring microphone and a 2into 4 dsp......dont know how to use either yet.



Had a kerfing disaster, the old triton isnt accurate enough, it needs to cut just right, bit ambitious trying to do it in one piece. Will have to try and do it in 2 pieces next.....need more MDF.





Bloody curves! See why most do box shaped boxes, nearly threw the lot in the bin and went back to the drawing board.....but persevered and got it done. Now I have to work out how Im going to clad them.

Hi Paul,

Looking good and full marks for persevering 

Also been here this week:

nearly threw the lot in the bin and went back to the drawing board

also and still persevering

Thanks Keith, Ill keep going then.

Cut holes into the top and bottom voids and added some more wood for strength. Filled the bottom voids with river sand (after I dried it), to suck up some vibration and so its not so top heavy.


Painted the internals with bitumen paint, cause it seemed like a good idea at the time.


Bought some Merbau 70 X 7MM X 5.7M slats from the hardware, cheap at less than $6 a length and some pine cut to the right thickness for the curves.










Do you think I went too far this time? Sometimes I think I should be a little more subtle hmmm










BTW is it OK to put the 2 x 3" ports in the rear?

[Pete_fi]

  JUST AWESOME!!!

[ropie]

Absolutely superb, Paul!!  They have a slighty 'voodoo' look to them  

[awty]

Thanks guys.

Enough already, here they are, kindly modeled by Jasper the wonder dog.

Still need to work on the minidsp.

[Rotsch]

Hi Paul.....

That is.....an absolutely stunning work !!
How comes...that you've got those ideas !!??
Too much sparetime, eh !!??    

 

Serious....amazing craftmanship !!

Wanna say something bout it.....and don't get me wrong...
First time i saw them....it reminds of a "Wurlitzer-Musicbox" ..especially your sketches
But every time i look at them now....i got somewhat of an "Aussie-impression"   ...Really !!
This is kind of "Aboriginal-Voodoo-Magic-Power"........      

Outstanding job !!!  

[low pitch]

The art deco cabs look fantastic with the patina copper horns on top, set off by the art deco dog and armchair of course, thanks for great photos, work of art
