Mountaineer Man did the design. I am going to start on it tomorrow. I can't wait. It's for a pair of PB-B1254v.2 12's powered of a Cadence z8000.

any reason for the angle in the internal wall?

That looks like an immense port with very little net volume, unless its not to scale.

Specs?

36W x 14H x 20D.

He said that it his version of the double shot??

it looks like youre getting less then 2cuft for both subs with like a 50+ inches of port, that thing have got to be tuned low as hell.

im interested on how is going to sound once youre done building it.

That's tuned quite high it appears. Also, why is there a bend in the port panel?

how did you figure its tuned high,

edit:

im sure itll peak high though

I figure because there is a HUGE port and next to no Vb. More port area = higher tune, and smaller volume with given port = higher tune. Put them together, and you can do the math.

Look at the length of the port though, prolly tuned lower. Like 33Hz is my guess.

i was thinking may be some were around 35Hz, but by using the diameter of the sub cut out as refrence.

posibly a 48" to 52" port thats mabe 4" wide x 13" high @ 2cuft, maybe 40Hz~ 45Hz tuning freq.

can Rage00 or Mountaineer Man share some specs on the enclosure.

The port is very long, which makes the Vb go into the tank. Specs?

That is one strange bend in the port wall.....

Taken off.

Only guesstimating, I am getting around 1.75 cubes. How wide is the port and how long?

NM, I see it.
