banginsebring07 Posted March 27, 2008 Author Report Share Posted March 27, 2008 ok so make sure i've got this right. If i go with a 2 or so net cubic foot box, after i add on port, sub, and bracing displacements it shouldn't be over 3 cubes total correct? And that 20 square inches each? is that for sub or per cubic foot. Quote Link to comment Share on other sites More sharing options...
Ray Posted March 27, 2008 Report Share Posted March 27, 2008 you should have 3cuft net after everything. and 20sq in per woofer is ideal.

SPL2K Posted March 27, 2008 Report Share Posted March 27, 2008 ok so make sure i've got this right. If i go with a 2 or so net cubic foot box, after i add on port, sub, and bracing displacements it shouldn't be over 3 cubes total correct? And that 20 square inches each? is that for sub or per cubic foot. using your dimensions... 35.75W X 11T X 25D you've got 4.42 cu.ft. Build the box that size with the 4 8's along the front of the box with a slot port along the bottom right below them. The vent should be 34.25W X 1.25T X 18L. That will tune around 37. Divide the center of the vent with a strip of 3/4 for a brace. Quote Michael Hughes = 6X SPL World Champion - Loudest on the planet in db Drag, USACi, and IASCA.

banginsebring07 Posted March 27, 2008 Author Report Share Posted March 27, 2008 Ok, now i'm confused. First to go with .75 each which adds up to 3 cubic ft, but now you are saying that the 4.42 cubic ft. box would be fine also. Sorry to be a pain, i just don't want to risk this poor fellers subs, if they were mine, i know what i would be doing the box a little differently.

banginsebring07 Posted March 28, 2008 Author Report Share Posted March 28, 2008 ok i guess i misunderstood you then. I though when you said .75 after displacements i thought you meant that was after adding them on. So it would be like .75 cubic ft. and then add on the port and sub displacement which would make it for example like 1.1 cubes correct?
