There is a contact page on the DSS site also. I'm normally able to answer or at least notify receipt of emails daily.
I notified my supplier again yesterday that I need another update and was told I would have one shortly. I currently have nearly all parts except the motors from China.
The motor order was actually ordered in May and I was quoted about 3 1/2 to 4 months. So I figured well I'll open a preorder, add a month to the ETA and get the subs to customers a little early. Well we see how that turned out. To prevent this issue again I won't offer preorders in the future.
On a good note a 2014 12" model will be on it's way to Taylor on Monday and a Trident in a couple weeks when they arrive. After he's finished with his testing I plan on doing a raffle on the subs and donate the proceeds to a charity that forum members prefer.
