Six sides to a box, so therefore you are doubling the layers of MDF, right?

Are you looking for corner lap details, internal bracing or wood glue advice?

Wow, I had to wait 12 hours for that post to be approved.

Sorry about that. 12 hours is unusual. Sometimes there just aren't any mods online to do the work. It's normally much faster.

An externally hosted image should be here but it was not working when we last tested it.

2 boxes, so 12 sides total - now I get it.

Is there a question or are you just posting an intended project?

 

[nulesus]

My second post is missing...??? This is ridiculous.

The first panel (baffle) is facing the listener. The remaining 11 is at a 90 degree and layered to together. I want some help, ideas, and suggestions before I take my plunge router to the stock. So this should be a T-Line with 11 layers of 3/4" MDF 8"x48" plus the front baffle (8"x36") for each cabinet.

That is not a very efficient or cost effective way to build an enclosure. You could get both boxes of that size from that amount of material and have some left over. It would take less time to build as well.

Thank you, but that is not the goal here. This is a research project. Efficiency and cost are not the objective right now. I appreciate your help though.

Well, what I was trying to say is there are several correct ways to do something and then there is the way you SHOULDN'T do it.
But it's your time to waste, so I'll leave you in peace.

This is the quickest way to test the curved cuts required for the inside layers. In other words this box is just a test dummy.

I guess I'm having a bad day, but what exactly "is" your goal, or at least, what are you researching?

That makes 2 of us. The goal is to make an effective T-Line vertical array.

 

[nulesus]

Can anyone suggest a pattern to cut for the inside layers? A curved trumpet shape or something. Leaving 2 panels for the outside. Preferable with the terminus exiting toward the ceiling.

Something similar to this perhaps...

Or usually the best way to get optimum sonics out of a panel. But it is MDF, which isn't very good speaker building material to start with.

Please tell us more about the goals of the experiment?

Tritrix TL

Reportedly not a very well done TL. But a pretty straightforward folding (One of Bob Brine's projects the 1st time i saw this particular fold.

Best achieved using flat material in the convential way.

Great now where getting somewhere.
Yes I have watching Bob Brines projects for some time. MDF is fine for this stage. The material used in the final design will be different. But it must be cut this way. It's a very dense material. The end result will NOT be flat, for it is molded. So at this stage, MDF will do for now.
