I have a 10 inch W0 for sale. It is practically brand new, it was in my car for a couple days. This is the new version of the W0 from JL Audio which has a rubber ring where you mount the sub instead of that crappy cardboard stuff. There is only one flaw that i can see on it, and it is a very small indentation on the dust cap about the size of the tip of a pen. 60 obo
