Box is 37" wide and the port is 6.5" wide this means that (2) 15's wont be able to be side by side.

I'm considering having on sub placed on top and on the front panel.

Has anyone ever tried this?

What side effects would I see from doing this?

Check out this video and let me know what you think...

Im pretty sure the magnets wont touch. This sketch isnt exact I just put it together real quick so you can get a visual. But if they are too close to each other I can offset them to fix that issue.

Any other input?

umm logically i think the sound waves will have a different pattern and run into each other....? (not totally sure, its physics and i'm no physic buff)

Thats a hellova nice box steave meade made.

What if I invert the sub on the top? If I did that I would have to change polarity to keep it in phase right?

LOL, thats funny you post that, I was just talking to 9912ds on AIM and he was tellin me about his setup that he bought from nG. He has the polarity changed on all the inverted subs.

I just noticed that Meade used (6) 6" ports which means those (4) 18's only had 113sq.in. of port area. Doesnt that seem like thats not enough port area?

Shoot maybe I should just go with (4) 6" flared ports in my design which would be 75sq.in. of port area for (2) 15's.

Im pretty sure its not just the subwoofers....Its about how many cubic feet the box is

What is the OD of the subs? You could mount them offset to gain a little more room: top left/bottom right on the baffle........

Indeed. Do it.

Invert the one on top, and reverse the polarity to keep the phase the same...

that box was designed for that small amount of port area. Me and Dave at RE came up with it on a napkin and a long distance phone call.......it is really hard to believe it but ya it worked pretty good. It slammed hard as hell, the only reason i even built a new one was because i dont like only seeing 2 of my 18's when i look in the rear view. I like to see all 4 gettin up :D

anyway that pic was the box i took to 2004 world finals for usac. so its been a minute since its been in my truck :D
