by the way... those specs i posted about my box were all divided in half... so ya, its a dual box... the full specs would be just, double the front/back panels and double the top/bottom panels... =)

Size is a big issue with ported boxes.

The issue with both sealed and ported is bracing and no unexpected leaks. Basically any flex in the box will reduce bass energy and make its own resonance sound. Leaks and flex will make the bass will sound muddied and reduce the SPL. i.e. NOT "hit."

The reason we were talking about size is because an inch off one side WILL ALWAYS change how the box sounds. You should take the time to estimate how your sub will respond to the size box you have.

Anyway. IF you brace that generic box you have AND seal it like crazy it probably won't sound like crap.

We all sound skeptical because box "hacks" like this rarely sound great.

i am not doing anything to the box besides taking out 2 walls in the middle... of the 4... and Sealing it... it wont leak with the foam tape i use... its like caulking... and it works perfect... the box is built tough... there will be no leaks... and it there is a rare leak... sum caulking will do the trick...

Hello Kapping.

I don't think you are understanding the baffle wall cuts we are listing. We are telling you what size to cut the wood to form an enclosure. We aren't giving the outside dimentions of the finished enclosure. I calculated the enclosure size you will end up with from the dimensions you provided, and figured you will have a .87 cubic foot sealed enclosure which is too small for the Shiva to sound very good in. They really need about 1.2 cubic feet for a good sound. And I may have misunderstood you, but I thought I read that you were going to put both Shiva's in that small enclosure. That would be even worse. Shiva's are great high efficency subs, but need some room to sound best. If you are looking for a lot of output in a tiny enclosure, then I would recomend choosing a different sub. But be warned that you are going to need a lot more power to get that output in the tiny enclosure. You just can't beat Hoffman's Iron Law.

Klapping, sell your current box on ebay before you rip it up and then go buy a sheet of .75" mdf and some screws and make a new box. It will sound alot better than your current one like Stephen said, and you will have the satisfaction of making your own box. Shivas - Page 6 -- posted image.

my box is a half inch off the exact recommended enclosure size from adire audiop's website... i think u guys are a little wrong here... i think the people who made the subs, have a little bit more knowledge on what size box, for their OWN subs... and like i said...

Its my dimensions, Times 2...

Do you have a link to where you are getting this recomendation from? I work for Adire and know the subs very well. If your enclosure is .85 cubic feet, then it won't sound very good.

What do you mean it's your diminsions, times 2?
