Was searching for a enclosure building program today and found a BASSBOX 6.. a $130 program for freeeeeeee! lol.. Its really indepth.. Its gonna take a whole day(just me,silence, a couple energy drinks and a pack of smokes) just to figure out how to negotiate the program. Who knows how long itll take me to actually enter in EVERY dimension and make a usable equation.
I knew trigonometry and algebra was involved but i was dumbfounded..
I'll keep u updated!
If u dont hear from me in a few days send help. lol

have ya used torres calculator at all yet? lol if your brain gets to over loaded from that program n havent tried torres and want to let me know lol its very easy and straight forward. cut sheet list and all it figures, and is accurate too, unlike the RE enclosure calculator. im one that likes/needs things to be simple lol

available in software or paperback? sounds easier... no need to make things harder than need be.. ill check it out
Do u just enter in sub dimensions, cu feet desired and it figures out the rest and gives u options?

its very easy and free DL. its from a guy on SMD and been worked on for a while to get the bugs out. its really nice i think and alot of people been using it. built my last 3 boxes with it and they sounded awesome. http://cid-1e28f7d3956a626f.skydrive...x/.Public?uc=1

and heres the link of where it came from so no worries about a random DL lol

hell it even works to figure out what a prefab is tuned to and all that lol. very easy and you will be wanting to build some boxes after messing around with it lol or maybe thats just me lol

+1 for the Torres Calc

That'* all I use anymore...I have BBP6 but it'* way too much for me. I don't know nearly as much as I need to know to use that program yet. The Torres calc. is easy to figure out, easy to use, very lightweight (not a resource hog) and is legitimately free! The only thing I don't like about it is the cut sheet layout.....I like my boxes to have a solid baffle with no edges showing on the face. With that calc it does a cut sheet to where you see the edges of the top/bottom and sides all around the baffle. Me no likey. So I just modify the cut sheet as needed so I can put the box together how I like, not a big deal at all.

WOW! Yea that program is WAY better.. SO easy to use. I just entered in approximate dimensions.
17x42x30, with a port 3x38x20. And came out with 10.35 cu ft, not including woofer dispacement. . Which maybe a little large. tuned to just under 36hz.
AWESOME

Your port dimension is way off! The dimensions for the port in the ExpoSport Calc (as I call it) are width, height and length. Since the height of your box is 17", your port is going to be 15.5" tall.....i'm assuming the 38 and 20 measurements are the length you want each wall of the port to be. That would be a 58" long port in the calc. So your port specs should be 15.5x3x58

But.....

I just plugged in those numbers and it'* not good, you'd end up with a box with an internal volume of 8.43cu.ft. and tuned to 15.10Hz., and this is before bracing and woofer displacement

yea, wrong dimentions in the wrong spots.. lol. Was just messing with it

Just keep in mind the type of box you're designing when you use that calc. because you may or may not need to add more info than just the height/width/length of the box and the port. Example, if doing an L-port box you would need to enter "2" in the box that says "common port walls" since 2 walls of the box (back and side) are also used for the port. That changes things if you were to leave that space blank.
