Box Design Software

[netcsk]

I'm here at work (Panasonic) and am wanting to build me a new box for my Xplod. I'm looking at different areas in the trunk (any ideas? -- I can do fiberglass or anything at work here for free).

Once I test my xplod in the chamber for the most accurate specs, does anyone recommend a program that I can use to calculate the size, with me being able to control at least one of the deminsions of the box (angles). If not, I can do it by hand, but of course I'd rather not.

I like TermPro. Expensive as hell, but is the only software I know of that will accurately design ported boxes and tell you the velocity of the air in the port.

If you are going sealed, whatever, just guess it. It isn't like there is any actual "design" in a sealed box...20% variance in size is close enough.

Bandpass or transmission line (oooOOOh baby...20 cubic feet for a 12", YEAH RIGHT!) is far more detailed...but the cheap way to go here is at http://www.carstereo.com/help/Articles.cfm or Unibox http://www.pvconsultants.com/audio/boxmodel/unibox.htm.

If you are thinking of TQWT or some folded-horn kinda thing, well, just quit it.

Did you read "The LoudSpeaker Cookbook" by Vance Dickason?

Buy it. Read it.

Yeah I've read it, we have multiple copies at work. I find it... very basic and over simplified though. The newest version at work is from 98, so some of the amp techniques and head unit stuff is outdated, which is annoying.

I'm probably just gonna go sealed. I suppose a 1 cubic foot or so box will be fine.

Any ideas on trunk location (I can't have it blocking the skiport though)?


Another thing, I saw that it is recommended to have the tweeters and midranges withing 6" of eachother up front to keep from having imaging problems (this makes sense). Of course, on the e30 they are a few feet away. Is it a big/noticeable problem? I would think so, but I don't have tweeters in mine currently.

We're building some samples for testing and curving at work. Including multiple samples titanium, aluminum, magnesium, kevlar, etc. The results should prove interesting, and of course, the best two out of the group will be coming home with me.

Unless you're a REALLY anal audiophile, I doubt you'd even notice any imaging problem on the e30's stock locations. I suppose there might be, but for the life of me I couldn't tell.

Hope this helps.
