Do I have my stuff straight
I have tried building boxes using bbp 6 and either I am idiot or something because they don't come out correct. I am trying to construct a box for my friends two L7 15s and I want to be sure my thoughts are indeed facts
a) you tune the box, not the subs
b) you make the box bigger to account for the sub displacement. Ie a box that held two subs that displaced .5 cf would have to be acutually build 1 cf bigger. For instance, if you wanted 2.5 cf per sub, you would make the box 6 cf to account for this used area.
This is actually a question:
1) Do port length calculators, such as the one for precision ports take into account the displacement of the port. The port does displace some area, correct. And that area would affect the volume of the box and therefore affect port length tuning. If it does not, I would have to make the box bigger correct?
2) What is the displacement of a 2006 L7. I learned through the sticky it is Sd x Xmax, neither which are published in the manual.
