if you want to tune lower, use a 4" and a 3" port for each....but make them 20+" long

I know if i use bigger ports i have to go longer. i wanted to know about the hz rise with power increase. what is the best way to find the tuning of the box. should i measure the amperage on the terminals or impedance rise or what ?

what was the name of the sub in the 4th picture next to the pheonix gold? with the 'A' on it?
I built some kid a few boxes for those back in florida. I did have a couple designs that did some CRAZY subsonics for one of those.
The thiele-small parameters were different in different places. Website, manual, and box all had different specs.
