Box help

IMO, 1.49 is pretty small for a 12 that is basically getting RMS. I suspect that f3 will not be very low, and I suspect you will be losing the output that a larger box typically garners

That's the recommended on the DC site.

Most DC Audio subs work in below average sized boxes, if fact the Pioneer TS-W3002 is recommended for 1.2 cubic feet ported and still gets real low.

Okay.. but yet I need a 12 inch woofer in there.. with 11.5 as a height how's that work?

The cutout diameter is 11" so it fits..tughtly, the outside diameter should be around 12.5" so it also fit.. you will have 1/4" clearance each side..very little, in fact I had to go for the all across Width/height baffle for this reason.

Damn, haha so the rubber will fit as well on the box? Also, how would you suggest cutting the port for the box? Being that I have to cut through the double baffle and make a perfect retangle box.. Does the port HAVE to be on the double baffle? Rather not cut my port.

i'm trying to build a box for a mayhem 12 thats why i ask....i wonder if that box will work? what do you think?

This box simply can't work with your mayhem 12", this sub needs 1.75-3 cubic feet to work properly.. I could suggest you an enclosure for that sub if you wish.

I use the following assembly style most of the times:

But on 13" is not possible, you would almost cut the baffle in two pieces if you tried.

As do I.. I could give you a higher height.. I'm trying to play it safe being that I made one box and it was to tall, w asn't enough room for the sub to flex.. would have hit the roof.. guess in this case i'd be safe since the sub isn't facing up. Give me one second and I can give you a higher height if your willing?

15 3/4 would be my measurement for the height.

It can be done as follows with the alternative assembly method:

Enclosure Specifications:

Fb = 33 Hz

Vb = 1.505 ft^3

External Height = 14.25 in

External Width = 21 in

External Depth = 18 in

Port Width = 1 13/16 in

Cut Sheet List:

* All Dimensions in Inches.

* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

Front = 18 7/16 x 12 3/4

Front Internal = 16 15/16 x 12 3/4

Back = 21 x 12 3/4

Left & Right Sides:

Side 1 = 16 1/2 x 12 3/4

Side 2 = 17 1/4 x 12 3/4

Top & Bottom = 21 x 18

L Port Internal Assembly Parts:

Front to Back = 14 11/16 x 12 3/4

Extension = 15 x 12 3/4

Same assembly guide as above:

Beautiful, mind telling me in a decimal what you put for port width and also what you put for length? I understand 1 13/16 for port length but what's that in decimals?
