What causes box rise?

As the title says.

What causes a huge box rise?

Small box with a huge port? or huge port in general? or small airspace?

Discuss please. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Old Thread with lots of good info on it. Been discussed many times... but impedance is the dynamic resistance generally attributed to the AC current in the coil.

From my experience, small boxes cause more impedance rise, but also have a higher SPL peak.

One aspect to SPL tuning is finding a compromise between the two variables, to drop the impedance, to maximize amp power, while allowing the sub to efficiently produce a frequency.

i heard that anal beads hanging from your port brings down box rise
