Just wondering... would my box rise change with different burp volumes?

For example.. if I normally burp at volume 25 and my box rise is to 1.6 from .05.. can I expect that it would be the same at volume 20? [Confused]

(I know I can test this myself... but I'm at work and was thinking about this question.. so I figured I'd ask and maybe save myself the test in case someone else happens to know the answer!)

you'll probably have less rise at lower power.

ABSOLUTELY!!!

It changes with temperature, excursion, compression, power, etc....

The trick is too get a woofer to change as little as possible within a sweet spot per user.

Usually the rise is higher at lower volumes and when the amp gets close to full power the rise is the lowest from what we've tested. maybe due to woofer compression, not really sure why.
