Any update on this project, eager to to see whats happening.
Like the design a lot.

Thanks 

I have everything ready and waiting - just need to finish up some other work before I start making sawdust...

Kind regards,
Ian.

Lovely design Ian.

New preamp in the making. Prototype playing at the moment. Driver triode running with CCS on the plate and battery cathode bias

Hi guys!

It's about time for an update on this project - I finally had some time to start cutting some wood 

--- CLICK FOR LARGER IMAGES ---

I start out laminating up 2 pieces of 15mm Birch ply for the baffles.  I do both baffles at the same time:




After some saw work to trim the edges down to size they go onto MountainMan for some milling work from the back side:







...after which they are flipped around so I can mill the front recess:










Test fit a few of the drivers:







...more to follow later 

Kind regards,
Ian.

So I will use (10x) Scan speak discovery 15W/8434G-00 for bass and midrange duty (because I have them) and the tweeters will be Scan speak discovery D2608/913000

You seem to have changed your approach slightly with the mid?

This is really looking good.
Do like the birch wood.
Eager to sea the rest.

Interesting... you're not worried about standing waves between the extensions of the side panels poking at at the front? To keep the simplicity of fabrication, maybe carve out circular cutouts either side of the drivers running from the front backwards (parallel to driver axis) on either side?

Maybe something worth considering, create a diffusion surface inside to reduce standing waves within the enclosure, so that you won't need too much damping?

And stand it on some stainless steel tubing on a plinth to lift it off the ground (cantilever?) and give it "air" in the design.

Standing waves need to parallel surfaces to develop, so that should not be a problem here, seeing that the extensions are at an angle to one another.
