What is the plastic diffuser material you are putting in behind the bubbler tubes? I just re-read the last post and didn't see it mentioned anywhere.
Also, have you looked into diy vacuum forming to make plastics similar to the original bubbler machines? I've seen people make small to medium scale diy vacuum formers. I figure with your skills and access to shop grade equipment, you might be capable of making a 2'x3' vacuum former.

I used a 2' x 4' light diffuser from Lowe's. It cost $7. I did look into vacuum forming, but I just don't have enough time to truly make it happen the way I would like.
Here is some more pictures I took tonight. I remade a few parts to adjust how things fit together. I also remade the insert piece so that the middle monitor was angled back two inches instead of two and a half. The speaker holes were a little small, so I remade that, as well as a couple of the smaller pieces. I slapped it all together with the base in just for poops and giggles.

If you use a serious speaker system like you did, I would try to make the casing of the speakers more sturdy. Maybe you need to segment it, give each speaker its own box, and for the woofers the box maybe 1.5 inch thick on all sides. Try to keep the boxes from being too rectangular to reduce standing waves. This is especially true for the midrange. The woofers produce too long waves to be affected by a box around 1 feet dimensions. Also fill the boxes with cloth or rockwool. Keep the opening for the wires minimal. Otherwise it is almost a pitty that you bought woofers like that. You limit 80% of their potention if they are mounted in one big hollow space with only 3/4 inch panels. Guess for the weight of your speakers, around 100lb of MDF may be necessary for casing the speakers themselves already.

I really been wanting to make a juke now and one of my concerns was high powered vibrations. Is this ever a concern? I mean here you have a pair of (i think 12"?) high powered subs that are all going to be contained with the rest of your components, pc stuff, touchscreens, etc. Will the stuff be vulnerable to damage from vibrations? If so what do you do to address an issue like that on this project? (might not be an issue at all, just wanted to check) Also, what brand/model are you using again for an amp to power the big boomers?
So far it's looking great and you are moving super fast on it, thanks again for sharing your projects with us.
Edit: That's funny, I didn't read blankas post till now. I think his idea is addressing that type of concern??

So what do you suggest...smaller? I think those are spot on for this size of juke myself.
