well i got a email today from Scott at Fi and this is what they had to say in regards to my 15" BL.
Thank you for the order, but we currently are having issues with our latest order of cones/surrounds. The 12" and 18" came in as normal, but the 10" and 15" had a different surround material on them. Although they looked OK, we decided to play it safe and do some destructive testing on them before we used them and came to the conclusion on Saturday that we do not feel comfortable with this different material. While we didnt have any catastrophic failures, we did notice fatigue marks that normally do not occur with the correct material. Due to this, we would like to ask you if you would like to continue with the order and wait for the correct surrounds to come in (we were told 2 weeks) or to cancel the order. If you should choose to keep the order, we would gladly throw in a sticker pack as well as a t-shirt for free too. If not, please let us know and we will cancel the order and refund your payment. I am very sorry for the inconvenience. Thanks, Scott Fi Car Audio
So its either wait for it and get a sticker pack and a T or....order a 12 or 18....i think im going to wait.
