I currently have a Digital Designs 9100, 12" sub in a sealed box. My
Autotek amp only pushes 500 RMS, though, which is a lot less than it
can handle, so I'm changing it over to a ported box.

This is an older sub, and I don't have the spec sheet with it anymore.
Does anyone know the displacement of this sub? I used to always add
0.1 cu.ft for displacement of a 12, but this thing is MASSIVE, and I
know it takes up more volume than that. I'm guessing that it weighs
around 50lbs.

If you don't know the displacement of this specific sub, then how do I
figure the displacement of the sub for myself? I'm not exactly looking
forward to dropping the thing in water, so I'm hoping that a measuring
tape can get me out of this ;-)

TIA,

Mike

Not exactly sure if this is dead on but according to the DD web site it look
slike its going to be about .13 cu ft

Sorry I meant to say .16 cu ft. I was looking at the 9000 series sub.
