You'd probably want to go with about 1cf per driver tuned around 35hz.

I'll figure the box up as common chamber.

The port is a 2x12 slot, 16 inches long. This occupies about 0.25cf counting the MDF used for one of the port walls (we'll have the port against one side of the box, and between the top and bottom, so only one port wall has to be constructed).

So, we're going to want a total of about 2.5cf before woofer and port displacement.

Our external dimensions will be 13.5H x 33W x 19.5D.

So internally, the dimensions for the woofer are 12H x 28W x 18D. This is because the port and port wall take up 3.5" on one side. On the other side we have the other wall of the box. We're assuming 3/4" MDF.

To make the box, you would want the following pieces of wood:

TOP and BOTTOM: 33 x 18" (so 2 pieces like this)

SIDE 1: (non port side) 12 x 18 (mounted between front and rear baffle)

SIDE 2: (port side) 12 x 18.75 (slightly longer because this side will act as other side of port wall, and must be flush with front baffle, but still in front of rear baffle)

FRONT: 29.5 x 12 (sits in front of sides and between the top and bottom, port goes next to it)

REAR: 33 x 13.5 (Just as high and wide as the box, cannot see any other piece but the rear from the rear view)

PORT: 15.25 x 12 (Sits BEHIND the edge of front baffle, so they are flush and to make total length 16")

testes?

its a box warbleed was kind enough to help me design a few years ago,

I checked the specs and I can still build it and use my old MTX's in it if I do it right
