the subs are 18.3? outside di...with the box above i only have 17.5 across the baffl...should i make another top and bottem, or just move the 12" out to 13.5???so the sub will clear, or put the outside wall to the side of the box not on top?

im ganna just move thw inside wall a bit, and well see haw it works, i think from a spl point it will be fine ??? but well know soon

BOX WILL BE DONE FRIDAY...THEN THE PICS!  :D

a wo with 18s is gona be so sweet, pity your butchering it for spl? maybe when and if you get bored of a fart box you can modd it back to a sql box?

Hey Josh!
How high was it tuned???
It might be a simple matter of that port side being too large? Could you slide a board in there to make that hole a little smaller? It is only 1.25" in the original. (If you think the tuning is the problem.
If it only did 135, it might be what I was talking about originally with the whole "size of horn" issues. That was the reason I had that huge design with the horn folding into the center at the front.
I would still love to play with that, but it is one of those things where wasting wood is a definite possibility.
So what's next for the big boys?
Wanna try a TL?
lol
Let me know what's on ya mind.

Later,
Robert

NEVER SAY DIE [/quote]

close the port / throat up to 1.25 inches. you havent wasted the mdf and time, you just need to 'perfect' it.

You know, I just checked some numbers and me thinks the sealed chamber on those 18s might just be toooooo small.
Assembly shows the baffle board inset into the center boards so that won't be an easy thing to change.
Let us know if you played with it any Josh.
I hate it that it wasn't a success on the first try, but I think it could be worked with maybe.
I had the thought to tell you to seal the box up, cut holes in the top and mount the woofer to the outside to see how it sounds lol.
Hey no experiment is a complete waste.
I would like to hear the difference with the port closed down a lot though. That may be all it needs to completely change. Of course, those 18s just look TIGHT inside there.

Give us an update when you get a chance man!

That's a thought.
Remember how huge the box designs were that I sent you for 4 15" subs/ It occurred to me that you are in a large van so something large might be in order.
12 cubes tuned to 35hz? that's for only 2 subs right?
180" port? hmmmm I need to look up the definition of TL, that might be approaching it already lol.
Keep us posted. It might be that the current box is still useable, but I am thinking it just doesn't have the volume to develop a wave for that big driver.
Oh well,
Let us know man!
