Afternoon all, Just been putting my week old XLS200 through it's paces. I put a dance CD on to test it's speed. I noticed something unusual though - One track I tested it with starts off with no bass, then it suddenly kicks is all at once. Quite a fast beat, asking a lot of work from the sub. I had it setup about 80Hz with speakers set to small, and the volume on almost a half (too much methinks). The unusual thing was, For the first couple of seconds of this powerful bass sequence, the sub's volume seemed to decrease then increase back to normal. Then it would stay the same and was fine . It's as if there wasnt enough power/current being sent to the driver for some reason. I replayed the track 2-3 times and the same thing happened. It's as though once the sub recognises theres a lot of power required, it levels out and keeps up the power. Has anybody else experienced this with their XLS200, or any other sub for that matter? As you will know, the XLS200 is not short on power, so I cant quite understand whats happening. Any ideas folks??
