[QUOTE="xluben, post: 2177368, member: 568852"] yeah, it's pretty good. -it properly accounts for port and driver displacement when calculating net volume -port length is pretty much spot on with winisd and other equations i've tried -it uses; no of drivers, size/shape of drivers, xmax, and box volume to calculate port area (so no port noise) the nice thing about the last feature, is that if you want more/less port area just change xmax. also, you sometimes have to play around with the numbers to get the boxes to turn out right. it likes to give labyrinth style ports as well as goofing up the picture with some large boxes and wide, short ports. most importantly you really shouldn't use it's "Option Two" make sure [I]you[/I] know what box you want it in, and it will give you pretty good set of plans. if you let it decide what box is best it'll give some pretty goofy results. EDIT: well, i just tried "option two" with the specs for my drivers and it came out with a pretty decent box with the "SQL" setting: 4ft^3 @ 30Hz not too far off from ascendant's recommended 4@32 even so, i've seen other drivers where it throws out crazy numbers when you use that option, so it's not recommended. you should know what you want before you start designing a box anyways. also, the maximally flat setting would give a good box for home use (but not car audio) and the compact box is often so small it makes the port super long, and the gross box volume doesn't end up being much smaller. a few more reasons to stay away from option two.
