Desperately seeking conical rectangular TH

first it must be put in akabak,even then i dont know how to aproach the pathlenghts.
easyest way is to make a test box ,measure it,and adjust the lenghts from there.

Thanks

Corner Thought Process No 1

Concider this end condition. The panel is extended right to the back for half its width. This gives a single defined path for the horn. The size of the cutout can be adjusted, and should give an area for the corner turn that is equal to or bigger than the area of the previous section.

Now concider this end condition.
The internal panel is kept short of the back panel over its entire width. The path for the horn is split both ways.
The area of the turn can be adjusted as before but as it is twice as wide it can be half the height.
The advantage - as I see it is that this allows for a longer internal path length.🙂

So sorry about this but this is a monster thread and I'm having a hard time following along...

What's the most recent/most improved version of this sub? Specifically the design style attached. I like that design because its not too complicated and the wheels are a must. Are there any detailed dimensioned drawings anywhere?

I plan to make 4 of them next year as a senior project for my school and I need to come up with a budget for them. They will be used on our football field so 140ish dB should be perfect (not that that will be hit very often)
