Why is my Insignia NS-HT51 Home Cinema speakers subwoofer distorted at high volume?

  If your Insignia Home Cinema subwoofer output is distorted at high volume, it could be due to several reasons. First, the volume of the subwoofer might be too high, causing the amplifier to be overdriven; try reducing the input level control. Alternatively, the signal from the receiver, amplifier, or preamplifier might be distorted; in this case, reduce the main system volume or bass tone control. If neither of these steps resolves the issue, the subwoofer electronics may be defective, and you should return it for repair.
