Hi, I'm not sure I've filled out the parameters for a driver correctly in WinISD . It's hard to tell some of them so they are my best guesses. I don't think it's at all right though as it's coming out with 33007L vented boxes

I know it's not proper full range or very good generally but I just wanted to try making the "correct" enclosure; it'll just be used as my test speaker

For a start you have entered Vas as 833 litres. I can say now that a 3 inch speaker that is not going to be anything like correct. Check you aren't confusing cc and litres.
edit: just read the PDF. Now that's their stupid mistake putting Vas in um^2 instead of some normal unit. I'd expect nothing less from the Maplin Chimps.

Hmm, what to change it for? I can only get the Units L, m^3, inch^3 and ft^3, not anything squared. Any way to calculate it?
Other than that I think this is correct (I adjusted the units now I actually read how to do it )
Also, any idea if these drivers are still the Audax ones? They always used to be but nowhere does it mention it. If they are it may already be in WinIsd's database.

I suspect the real Vas is 0.83347 litres.
Be aware that the very high Qts means this drive unit may be intended for open baffle use such as ceiling mount or in open backed boxes. It cannot be used in a vented box.
As it's just a test speaker just stick it in any small box you can find. If you want a semi-accurate test speaker you can do a lot better at not much more cost.
