Software for speaker enclosures

[dvenardos]

I asked this over on Danny's forum, but it is pretty slow over there and I only got a response from Danny.
What software do you guys use for designing speaker enclosures that is easy and cheap?
I am having fun playing around with Danny's kits and the possibilities therein.

Thanks,
Don

Parts Express use to have a free download for a box calculator. Not as good as Bass Box 6, but it worked. This takes the Theil-Small parameters for the driver and gives a box volume for the chosen box response alignment.

Not sure if it gives box cut dimensions like BB6. Have not used it in awhile.

Thanks, looks like they don't have it available anymore. They are selling lots of speaker design software, so maybe that is the reason?

I don't recall if WinISD can model multiple drivers. It's what I used to design my subs though.

Free :cool:

I use Unibox:

I've read it has the most accurate models.

Although it will generate solutions for various alignments based on your input goals, you really have to 'try things' (vary box volume, port dimensions, tuning frequencies), recalculating the FR and impulse response each time, to get a picture of how a certain driver works in general. PRINT and label the resulting graphs each time -- it'll help you choose the response package you want.

HINT: For best sound, choose solutions with good impulse response.

Don, you probably already know this, but unless you are planning on tweaking Danny's crossover designs you'll have to keep the front baffle layout similar to what he designed for. You definately need to keep the center-to-center driver spacing within 1cm, and the baffle width within 1 inch, for best results.

If you want to vary more than that just ask Danny for an approximate x-o mod for the baffle design you want. If you've kept driver spacing the same and are just varying baffle size, minor baffle step compensation mods are often as simple as varying the wire gauge in one of the inductors.

Thanks. Yeah, it looks like it wasn't practical to do what I was wanting to do and Danny is coming out with a new design that will better meet my needs, so I will wait for that.
