I spoke with Beth at AE last week. The car IB 15" is $149 plus shipping. $100 per sub if you purchase 4 subs. Shipping from WI to most areas of the lower 48 states will run between $12-$18 if purchasing 1 sub. The wait period for building-avg 2-3 weeks.
"the issue right now is that the new frames we got are not the same 12 spoke frames as the old ones. I can't do IB15's with them"
I asked him what the ETA on when they will be ready and he said:
"not sure yet... frames usually take 3mos, well 2mos min, 30days to make, 30 days on the water"
He said he might air ship some more in but he wasnt positive about that, so judging by what I heard from John directly, it can take 5 months before you see your subs if you ordered today....
If it wasnt for such the long wait I would have certainly gone with AE IB15's
