IB in a hatch, anyone done it? Any reason not to try?

Next question :

Can I realistically model what I'm trying to do in WINISD? Let me supplement that question by adding that I've only tried the software a couple of times, and am still learning it. Any pointers would be gratefully received.

You should just be able to make the enclosure size either really big or as close as you can possibly get to the airspace the sub will “see”. For example my trunk is about 13 cubic feet or so (a spec I got off the internet listed as trunk cargo volume) so I used that as my sealed enclosure size. Most manufacturers will list hatchback cargo volume with both seats up and seats down if they fold. You’ll want to use the seats up spec obviously. If you can’t find the spec a rough estimate should suffice.

Thank you, Todd, that helps. I'll give it a try this weekend.

How crucial is it to enter the sub xmax into winisd? The Gladen sub I linked previously has most parameters listed, apart from xmax.

I'll email them and see if they can provide it.
