I finally had a chance to turn up the volume on LOTR the other day. During the first battle scene when Sauron's finger falls to the ground my sub bottomed out with a loud clack. Of course I had never heard a sub bottom before so I rewound and played it again to make sure it was the sub. Well it was and after the second bottom, it stopped moving all together. I have a Cerwin-Vega HT-S10A, or should I say HAD a Cerwin-Vega HT-S10A. Actually I called Cewin-Vega and It will be fixed under warranty. Thank god because I am planning to sell it to finance my DIY. I guess I have to be more careful next time.....NOT.
