Software modeling multiway speakers

[JammyBStard]

If I want to model an existing DIY speaker cabinet that someone else has made (with an eye to making it better) what software would you sugest; Ive used WinISD in the past to model a Bass box for the car, but I don't think WinISD lets you model multiple drivers in the same box.

What do people use?

There might be some help here:

But perhaps you could elaborate on what you mean by making the existing cabinet better.

SPEAK - GedLee LLC - will do that. And its free. Just not supported.

Well I have this cabinette (See Here) and the brief backstory is that someone has replaced the drivers in a large sealed cab with speakers from a pair of Heybrook HB1 speakers, which have much smaller cabs.
They do sound great and the drivers are in excellent condition but the bass is a little bit vague and could do with been tighter. I susspect these drivers could work better in a smaller cab so I was thinking of adding a bracing shelf to the cabs to effectivly reduce the size of the box. I was hoping using some modeling software could help me workout the optimum box size, and perhaps the crossover could do with a tweek.

The cabs are 53L, 627x235x360mm (HxWxD) Made of 12mm laminated Ply, no vents louvered baffle.
The drivers are both Vifa; Main = M21WG-09 8ohm, Tweet = D26TF-05 6ohm, the X-Over is from the HB1.

Try Unibox then.

Remember that enclosures must be designed for the specific application - drivers, etc., and that guessing as to the reduced size is a shot in the dark. Determine the optimum volume with the software and then add wood to the interior of the enclosure per the results.
