    In the beginning, it was making a loud buzzing, or fluttering sound that could be affected by tapping on the cone which lead us to believe it was the accelerometer. Since then, we have removed it. How can I replace this part?

    A fluttering sound likely means the driver is blown. You will need to contact Velodyne to see if they will sell you a new driver assembly. It should be fairly easy to replace, you just remove screws to pull out the old one.

    Hi Dave. The driver tests fine. After reading abut these, you'll notice the HGS series having alot of problems with the accellerometerr. When it fails, it cannot limit the distance of travel forward or back causing it to stutter.

    Have you contacted Velodyne about parts? It's likely they stock what you need.

    That's the problem. You'll read alot about this too, they no longer support, or carry the accelerometer and they won't give anyone schematics either.

    The only suggestion I can offer in that case is to pull out the accelerometer and try to see who the OEM is. They might be able to get a similar device for you. Beyond that, you might be stuck.

    Already pulled. Nothing but epoxy or some extremely hard resin. No identification. There's a guy in jersey that bypasses that but I'm looking at around $300.

    Sorry to hear that Charles - don't think we can suggest anything else at this point. This is one of the reasons I avoid Velodyne products, they just aren't easy to repair as they age, while an old SVS, Seaton or PowerSound sub will always be repairable.

    I'll probably end up sending it off to the guy in jersey and let him work on it. Only reason I got it was because it came with the home theater I bought.

    Repairing an HGS-15 is likely not the best choice as that unit is probably 10+ years old. The life expectancy of a high quality subwoofer is just about that - a decade - so it may be better to simply cut your loses and replace it with something more current.
