Change this design

[mikeyboc 10+ year member]

Can anyone help me change this design to have A) one port in the middle, or B) 2 ports on the sides.

It is for two ARC Flatline 12's. I was originally going to go sealed, but am debating tuning to 28 or so.

Will pay a couple bucks if needed.

Net Volume: 2.75 cubic feet

Tuning Frequency: 28.13 Hz

Port Width: 4.25 inches

Port Area: 61.625 Square Inches

Port Length: 69.75 inches

External Dimensions: 49 wide x 16 tall x 16.25 deep

that port might have a little too much area.. cuz its gonna have to be 70" long and with a box this size that is kinda hard

and i think you may also want to go with a little more volume to bring the low-end extension out some... it will work better if tuned that low

Well, it's going in the back of a Tahoe, and I wanted it to go from "wall to wall" in the back (49"), and flush on the top with the side trim (16"), depth is flexible, but preferably not over 15". I think I want to shoot for 28hz tuning, any recomendations?

u could do... 49x16x14 external, with a 10x2.5 port (50 in^2) 39" long

that would be jsut about 4 cubes net @ 28hz
