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.

Thanks for the post. :cheers: I have been wondering about the speaker box considering all six speakers were in the same space. I have a solution for that I believe.

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.

I didn't have any issues with the other juke as far as vibrations are concerned. When this is finished, I would be amazed if it vibrates terribly due to the insane weight of the whole machine. I am using a kenwood receiver to power everything. The speakers themselves have a small power unit that I attach the speaker wire to that control their output.

Oh yea i never thought of the overall weight of the juke to hold er down. I'm happy to hear this isn't a concern. I might have to consider some of blanka's suggestions for when I make one. I want to go with some big boomers myself and limiting the performance wouldn't be cool.

I decided to take the advice on the speaker box enclosure for the subs. Thought I would share a website that is very helpful in calculating what size the sub will need. :cheers:
EDIT: It would probably help if I included the website! :dizzy:

I hate you guys with CNC's... (man I wished I could have one too!)
Seriously, you are doing a great job!
Cant wait to see the final results.
