Hey guys, I've been researching and I think I am about to purchase a 12" Fi Q because of all the good reviews. I just have a couple questions regarding the sub itself. On the website, it can come with a bunch of options and I don't know what they are. Can someone explain dual 1 vs. dual 2, spider, P chamfer, I heat ring, high QTS, and cooling? What amp would function well with the sub? Also, does the Q sound better in a ported or sealed box?
Thanks so much!
