Posted March 22, 201114 yr Hi guys, Im not quite sure if I put this in the correct section but Im sorry if its not right. Anyways I found I really good deal on a W7 on Craigslist close to my house. I was going to call the guy and make a time to check out the sub. Im pretty dumb when it comes to knowing what signs of abuse are for subs but I was wanting to know in general what are some things I WANT to see as well as some things I DONT want to see (as far as whether I should buy the sub). I mean I know that holes in the subs surround or any cracks are bad but as far as the mechanics of the sub what are some signs of abuse. Hope this makes sense.

March 22, 201114 yr MAke sure the sub is out of an enclosure, hook it up and listen. If something sounds abnormal, don't buy it.
March 22, 201114 yr Check to see if the coils are working. If you have a 9v battery bring that and connect in series to see if the coils are good.

IIRC, the W7s have a very tight gap and the slightest rock could be disastrous. The IDMAX used to have this issue.

As far as "coil rub", I just push the sub up and down as if it is being played and hear for any rubbing noise?
