you could try to make the hornpath wider.mayby it would get a little flatter.i only tune down to 40 hz. its near the fs of the driver. this's the graph respond. ill post the plan dimension when its finish to build in the next time. thanks
the dip above the pasband is due to the big vtc.
i like to see the outcome
Best 3/4" ply I could find (baltic birch). At least it's 13 ply, right?
Where'd you find that? I've been going to Auburn hardwoods
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.

I will take this one
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)

hi kctess5
its "the standart fold"(there are manny like that)
this design is a 400 ltr cab designed for the bms 18 850v2.
wich driver are you planning to use?
i can sym it to see if it works in this design.
ive got the file on this one somewhere,i can give details .
edit/for outside i would bump the f3 closer to 40 ,adjust the design a bit.
this one or this one ?
