My IB3's shipped today. It was 9 business days and it will be 4-5 days for UPS ground to Central Illinois. I am putting two 18s in an infinite baffle manifold in my attic for my home theatre.
I ordered two Fi IB3-18s on the same day you did and have not seen the subs or any UPS updates. I am trying to be patient, but it is hard when you are excited about something. I haven't emailed them or tried contacting them. The more noise they get, the longer it takes... I just keep telling myself the wait will be worth it.
