Hey thanks for getting back to me on that. Did I see you somewhere on here talk about revamping the dcon line, are you able to give any info on them? Like, if optimal box size might go down, or if they might perform differently sealed? I would love to pick up a 10, from all the stuff I hear about them on this site, but im looking for a smaller box size than the 1.25 optimal ported, which is why I was considering the 8, but would prefer the 10. It would be going into a suv if that changes anything and using polyfill. Thanks. Ps anxious to try a ssa product! You are a company purely based in the states? I am from Canada, and was wondering if I order something from your website, I will have to pay duty on that right?
