How much do the 15s cost?

Call and ask them, but somewhere around $450 shipped.

I see no price or even order page on their website.

Because you need to call to get pricing or to order //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif They do have a dealer network that they can't under-cut by placing direct pricing info on the website. Also, they need to verify that there are no dealers within 50 miles of you before you can order

Not only do you have to verify that there are no dealers but they might ask you for a stool sample.

Also, what kind of dimensions am I looking at for both the 15" XXX and Brahma (minimum)?

For what, a box? The XXX needs about 2cuft, which to account for sub displacement will need to be around 25.5" x 13.5" x 15" (external dims)....that'll give you about 2.25cuft internal airspace (gross). After sub displacement, it'll give you very close to exactly 2cuft.
