peak freq and biggest voltage drop

[alaskanzx5]

so while listening to my music i noticed ( all stock electrical except a 10farad rockford cap ) that songs that play further away from my peak freq has less voltage drop. i peak around 45hz and drop to 11.9 full tilt from about 43-47hz. but when playing freq around 33-35hz i was only dropping to 12.1-12.5v. then anything around 50hz had a similar voltage drop as the low to mid 30's.

just wondering if this means that not only am i peaking around 45hz but is that also where im getting the least amount of impedance rise? not trying to combat rise or anything just something i was thinking.

It may or may not be where you peak, depending on various factors.

But that's where you have the least box rise

i know may peak is somewhere between 43-47hz, scored a 142.4 right in that freq range on a tl i just wasnt looking at the peak freq on the screen. was trying to push for an extra 1-.2 db.

i was just wondering because ive never noticed it before and i have never tested for rise. i just dont see the point in trying to combat rise. ill just stick with the constant power amps.
