So ive been trying to come up with a new box design for my 2 xfl 12s as some might have seen my 6th order thread...not doing that just going to try a different, slightly smaller, ported. As i just got my saz-3500, it doesn't seem like they want to take any more power than with my bc2000.
With the extra power im feeding them, i came up with a slightly smaller box, tuned a little lower, and "clam-shelled" back into the trunk a bit but still all sealed off.
Here is the chart for winisd which shows my current box(green) and new box(white) and both have a peak new one little bit smaller but winisd default will put it in a 3.5cuf box for 2 at 29hz.
EDIT:all numbers are with all displacement.
new box has 52in^2 port area by the way. and here is sketchup of current and new box as well. any way id really like input on smaller box/smaller port for more power? smaller box/bigger port? right now i just feel they could do more.
and new design:
