[QUOTE="denim, post: 7249052, member: 545441"] [B]Sure, there is always going to be more accurate, but in the end, there are SO many issues to deal with in car audio, in terms of the environment, I think we are starting to split hairs here. As for Q and Icon differences, there are many. Different motor all together (Q is a solid pole & single slug & steep backplate where as the out going Icon is vented pole & triple slug & and shallow back plate), different gaps etc. Q uses a aluminum coil, the Icon's primary is a copper. The Q has more thermal handling the the out going Icon, the Q also has more Xmax then the out going Icon. The Q has different suspension and different cone structure essentially, so different moving mass. Icon 12 Fs is 29.9, Q = 34.2. Icon has greater Vas. Q has a lower Qts. Icon has less moving mass etc.[/B] [B] [/B] [B]Essentially what I am getting at is once you get past the surround and basket style, they vary across the board.
