[QUOTE="husker77, post: 7802740, member: 641116"] Okay I ran it through winISD. The teal is basically the way I have it drawn in the first post, and the peach/orange is moving some displacement from the sealed to the ported section to try and get closer to the 3:1 ratio. Both seem very peaky. By making the sealed section smaller and the ported section bigger it looks like it would play a little louder, but not quite as low. But it looks like it would probably be inaudible. The other two are regular ported boxes with the area I have. The gray one is tuned to 34hz and the magenta to 28. They seem like they have better response curves than the 4th order. I don't know if I can go as big on a ported box because I have to have someplace to put the subs, if I fire them up they would hit the trunk lid, back and forward would also hit the trunk walls. So I would have to compensate for that somehow. I would gain some internal volume back from not having to mount the subs inside the box, or some of the walls for mounting the subs. I read through some of that link given earlier(only on page 14 of 100 and some), but it seems my subs may not be suited all that well for a 4th order, especially with the size constraints of the box.
