Software recommendations? Cab modelling & measurement

Hi

I'm on the lookout for some affordable cab/driver modelling, and measurement software that is affordable, capable, and easy to use. It would be really handy to me if the measurement software can model EQ / crossover filters, and ideally be able to overlay the theoretical crossover curves, so I can relate that to my actual acoustic response. I'm open to all ideas and suggestions. At the moment the only resources I have available are a measurement mic, REW, and WinISD online.

Your input is much appreciated, Thanks!

Boyd,

David McBean's Hornresp is an excellent free software capable of modeling almost any cabinet design's response. It also includes filter simulation.

Don't know of any measurement software that overlays theoretical crossover curves, but it is easy to simply look at a curve and count how many dB down response is an octave from the crossover point to see how close it is to theoretical. More important is to look at (and match) the phase response of the drivers through the crossover region, which you can already do with REW and the proper application of filters, delay, and EQ.

hey

Yeah there are three free pieces of software that generally cover you for everything design wise. You already have WinISD which is OK fro throwing quick ported/reflex designs together. As Art says, Hornresp is the next useful tool which will let you model various types of front loaded/ported/offset/tapped horns to great effect.

Finally if you want to get REALLY crazy you can look into Akabak. This is an old piece of software now and only runs on Windows XP, so you'll need to either have an older machine that still runs it, or use an emulator inside you Mac or newer windows machine. It's a programming script based program, so you have to write out your design in terms of a series of little statements describing each section of the design and how the horn paths comes together etc. Being so flexible, it can model any design that you could possibly imagine, but because of this it also looks a bit daunting when you first approach it. However there are a few tutorials that have been posted to various forums and once you see a few examples of different designs and look at the modelling script, it actually begins to make a lot of sense and you'll quickly see that it isn't all that hard after all.

In terms of crossover design, its more commercial software that seems to have that option. I know both LEAP, LspCAD and BassBox Pro have crossover design modules/companions that can be used to design crossovers to go with the speaker designs, and I'm sure others may too, but I haven't really used them so can't comment.

And as Art also says, in any case I would assume these crossover designs would be simple and have a crossover at a desired frequency.
