Box Rise?

How do you determine box rise? And what is the best way to prevent or decrease it as much as possible?

what do you mean like warped boards ? or just a cheaply made box ?? cause i never seen a box rise before . maybe the seals on the box isn't very good i used construction grade caulking on my box along with screws and wood glue

If you aren't competing it's not an issue to worry about. Every note offers difference amounts of rise depending on the enclosure and music is definitely all over the place.

Otherwise, a smaller enclosure and tuning 3-4 frequencies down from the note you intend to burp at would be your best bet to fight impedance rise.

keep your wires as short as possible, use the same gauge wire inside the box and to the amp. also everytime electricity has to go from a wire to a spade terminal to a speaker box terminal cup back to speaker wire...well that causes a little rise as well...so a decent short and simple way or rule is to: only use what you really need....so dont have 5FT of speaker wire outside the box. cut the extra off and stuff like that. also the guy soundstreamer is 10000% correct as well

In terms of DC resistance, not AC impedance.

This x1000. If your playing music it's really a non-issue. Impedence will be all over the place no matter what you do. If your only burping at a single tone then you can worry about it, other than that it's a waste of time to worry about it.

Lol, that's not what he's talking about I don't believe. He's talking about impedance rise (ohms).
