OK, so after much fooling around, I've determined that the qts is 0.45, the vas is 40 ft^3 and the fs is 18.5 . This is driving me towards a very large sealed box to get the system Q down below 1. Any suggestions on altering the vas? I'm figuring if I really stuff a 5 cubic foot box, the stuffing will drop the system Q. I would really like to get this into a 3 ft^3 box but I don't see how. Maybe applying some kind of goop to the spider?
