Started testing the tuning of the box. STV over on the DIYA forum did some really awesome research on optimizing ports. https://www.diyaudio.com/community/threads/investigating-port-resonance-absorbers-and-port-geometries.388264/
The outcome of it became a spread sheet that gives a proper geometric shape that keeps flow as laminar as possible to prevent port noise. Using this he was kind enough to model and send me a print file. I then had a buddy print up this first iteration to test.
I am shooting for 40Hz, this ended up at 35Hz, so the next iteration is waiting to be printed. This also coincides with me pestering 😛 @rjj45 to help me figure out port placement over in the Hornresp thread.
Today was a day I've been thinking about for awhile now. I've been thinking of how to cut the bevels on either side of the baffles..... without screwing something up. I came up with a plan for a jig and as I was building it, I really tried to make it work for cutting both sides. Here's what transpired:
It was definitely nerve wracking... knowing at any moment these baffles could be dumpster fill, but everything went as planned! This is after doing one side, reversing everything and doing the other side.
It was, but thats part of the fun. The things we have to invent to make other things happen is another aspect of this hobby I really enjoy. Wasn't there a thread where people were posting jigs they made?

Me too. The downside is the number of jigs and fixtures that I have made that have been "one time use" projects.
But Chahly - Stahkist don't want speakers that look good, Stahkist wants speakers that sound good!
Installed some braces for the bolts to mount the base to. I'll drill a couple 1/2" bolt holes through the bases up through those pieces.
Also got the holes done to mount the ports though. I'm going with a rear mounted port because of the tight space I have to work with to get it up above the mid pipe, behind the tweeter. Adam is printing them up in PETG CF. This was a trial piece to get the depth stop dialed in so it'll be flush to the outside of the enclosure.

I really wanted to get fancy and have a glass top for crossover viewing, but I just don't have the depth.

That looks awesome! Almost too nice to have hidden inside the enclosure.
Ah! There's the Audax!

Exactly as planned...
Very clever looking fixture!
Proper planning produces perfect projects!
You are one skilled puppy!
That came out fabulously, man.
Damn dude, even the jig was a lot of work. well done.

Insane amount of work you have put into these.
Me too. The downside is the number of jigs and fixtures that I have made that have been "one time use" projects.
So true!
Very impressive skill level here. Very nice.

You took the cabs to another level sir , good lord.
