Help with box design.

[shoban1]

Hey guys. I'm having a problem with a box design. I am currently in the process of getting 4 elite2's, and I am wondering on how to port the box. I can usually build what the manual say's but haven't really made a box with multiple subs. Mostly about the port tho. Do u just take the port size from the manual and X's that by four? or does the port go by the box? Any help will be greatly appreciated. Thanks in advance.

Obviously you just make a box with four times the recommended volume.

A box with four subs and four times the volume of a single box should be ported with four times port area. Port length will stay the same.
You can use four of the recommended ports and put them in the same box, but that is a waste of time.
Its easiest to use just one port with four times port area. This means a port with twice the diameter.

OK. Thanks a lot. That's what I thought but wasn't sure. Much appreciated.
