All, I guess I now know why it was an open box one... I bought my Sony sub open box on 11/10/01, and last week, I thought I heard a bit of a buzzing sound coming from it. Didn't really pay much attention to it, but now when the bass hits, it just buzzes and rattles. When powered off, I can push the cone in by hand and hear a scratching sound.... not good. Since I bought it open box, there was no manual, cable, etc with it, just the box itself. Anybody know offhand what the warranty is on these suckers? I'm guessing that it should be at least 1 year parts & labor, so replacing the driver should be no charge, right? Suggestions for a fast repair shop in the Cleveland, OH area? Any chance someone here has replaced/upgraded the driver in theirs and has a spare one for cheap? Thanks for listening, -Brett.
