Ported Box SIze question

HI, guys im planning on getting a Ported box for my 2 12' kove argamedon zd12. the Recommended enclosure designs is a 2.75 cu per chamber, But the problem is that it will be a huge box too big for my trunk, so my question is there any problem if i get a 1.7 cu per chamber. tuned at 36hz. Will this cause a damage to the subs?

im not exactly sure but make ur sure u put polyfill in it to help it out.

You have enough space for a proper enclosure with one sub but you want to put in two.  Common sense says you use just one, and when you ask "is there any problem?" then of course the answer will be yes.  I hope you're plotting this out with a design program if you want to change any of the manufacturer's recommended box specs....but I guess if you were you wouldn't need to ask about it.

The problems could cover the range of:  poor frequency response either in loss of low end or a peak in the output, inefficiency, poor quality sound.....

When a program (like WinISD) gives you a large enclosure size for a vented application it is doing so only because it looks at "best quality output".  But a manufacturer recommendation of size is also considerate of everyday needs and actual room to put the enclosure.  That being said, if Kove said to use 2.7 ft for one sub then they are confident that the results will be dismal if you used a smaller box.

Port size in length will most likely grow considerably as the box net volume decreases, adding volume to your space that will infringe on the available sub space.  Consider using one sub instead of two and get a different amp if you need to.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Stevdart's response above is 100% correct.  But let me chime in with a simple reply since someone PM'd me and said my posts lately are over people's heads.

Probably won't damage anything but will sound like pure ass.

lol!

DYohn, there are some people here that really enjoy your relatively high level posts. It forces us to do some work to learn the concepts. Learning the concepts, in my opinion, is more powerful and enabling than just getting the simple answer. Your opinion is so powerful and educational here because of the thorough nature of your posts. Just because your posts are over some people's heads doesn't mean you should change your highly effective teaching style.

So, my advice, my hope, is that you keep up your high level posts. Then maybe throw in the punch-line at the end, for those that really don't want to learn and just want the answers. :-)
