There is a time and a place for the alignment but it is nearly always completely misused. Complete internet boner. 99% of the boxes I've seen on car audio sites are completely fucked. What is amusing is that people will rant on others if you design a ported box strange, but add the words BP and it doesn't matter. Most are built with no scientific logic at all. Pretty easy to tell if this is you or not....just explain why you want the alignment in the first place.
