Well maybe im just confused...lol the one i was using uses alot less variables.
RE Enclosure Calculator
lol please read #1 of the Help window. also posted in the first post. the RE calculator is VERY limited. as in only a slot port with sub and port forward. no multiple baffles, no sub displacement, not sure what else.
thats the link.
So if i read the manual, check the total v of the box, then put the figures in this calculator, it will tell me if i need to remove or add foam for tuning? Sorry (i know im reminding you im from alabama right now) for all of the ?'s....
polyfill for boxes is a little different as it makes the box *think* it's in a bigger enclosure than it really is. hard to say exactly how big it thinks it is. the bigger the enclosure is, the shorter the port needs to be to maintain the desired tuning frequency
