Hey, I have 2 10" Infinity perfect 10.1 subs. I found the manufacture's recomendations that says for a sealed box there should be a volume of .6 cu ft.
The picture shows the sub in the box and says that it's with 1" of polyfill lining all sides of the box, but I don't know if the box size takes into account the volume of the sub it's self.
I already have 2 sealed boxes, but they weren't deep enough so I made wooden spacers. I want to start from scratch again and build the boxes the right size to begin with.
I need a box at least 7" deep (sub has a 6" mounting depth), so any recomendations on L W H ratios is also very appreciated.
Oh, I'm also going to have 2 separate boxes in opposite corners of the back of my truck's cab, with a small seat between them.
Thanks,
Alan

I cannot find published data on the subs' displacement or if 0.6 cf is with or w/o sub displacement accounted for. Best answer will come from Infinity Tech support.

Here's the site where I found the same sheet that came with the subs:
http://www.mms.ru/files/manual/infinity/kappa_perfect10_1_boxinfo.pdf
This probably doesn't help much, as it just shows the sub in the box, but doesn't tell if it's including the sub's displacement (although, it would seem that it would).
The specs of the sub can be found here:
http://manuals.harman.com/INF/CAR/Owner%27s%20Manual/KAPPA%20PERFECT%2010%20om.pdf
I can also try to contact the tech support like Swez suggested, but they say on their site that they don't give exact specifacations 'cause everyone's setup and vehicle are different...
Thanks,
Alan

Alan,
Yes, I scoured the Tech manuals already and came up with nothing that tells sub displacement or if box spec includes woofer displacement.
A typical 10" woofer has a displacement value of ~130 -150 in^3 (~.08ft^3 typ.) So, compared to a 0.6ft^3 box, the .08 is a very small portion of the overall calculation. For that matter, 10-12 oz of polyfill will add ~10% of appearant volume to a small box. Displacement is only 12 -13% of the equation here.
If you want a perfect fit and stay within 0.6 cf, contact Infinity to define the sub displacement # and if box recommendation is with or w/o sub displacement included.
