[QUOTE="asr10 user, post: 7629236, member: 613726"] Ok an update. I brought the sub in to the shop where I bought it and hoped to test it. I took the W7 bare with no box and the guy said he didnt have time today to put it in a box real quick to test properly, he said it will probably sound funny with no box. I tested it that way with no box. I also didnt have the O-Ring that goes around the top of the cone installed. He said he doubts the o-ring has anything to do with it, but it would be better to test that way. He also pushed the sub in and out and put something like a dmm onto each VC that made the woofer jump to what seemed like full excursion. He said it seems fine and the voice coils are ok. I asked him about the weather and dropping it and he says physically it looked fine so he doubts weather is an issue. And if it was dropped, you would probably see the magnet not be aligned and he has seen that before in other w7's. So in a nutshell, he says its probably fine, but I need to either come back when he has free time to put the sub into his box, or I can put it back into my old sealed box and he would gladly test it while its in my box. He did not test it while it was bare and boxless. He also offered to build a dual ported box painted or stained and designed for the home for $300. I might do that if the sub works. [/QUOTE]
