Dudek, so it's back to the beginning eh?  But I wouldn't have a clue if there was a typo in that formula or something.  But it sounds about right.  I get 3.02 % with my CV sub at 17 mm and 22 Fs.  And I know CV makes all their home subs down-firing.
Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Oops, my mistake.  The Infinity should be 3.32% like I posted in the early part of this thread.  Sorry.

ok, i've looked around at jbl,jl,pioneer and infinity (xmax) specs. it seems that infinity's perfect line are the highest. i still think my sub is operating outside of it's magnetic zone at high volume. am i just putting too much power to it? also, i've lined the box with polyfill. should i stuff the rest of the box to get the full potential of "polyfill"?

Back to the original suggestions.  Gain is too high, bass boost is too high, or amplifier is too large.  Infinity Perfect 12.1 handles 350 watts RMS.
