I have a DLS-5000R that I bought new around 2005. The amp went bad when the unit was around 6 months old. The replacement amp was also bad. I finally got what I thought was a good amp on the third try, but ever since then it has a distortion problem that is so annoying that I have not used the sub in several years. It seems to happen mostly when I'm watching TV or recorded videos at low volume. The speaker puts out what I would describe as scratchy/crunchy distortion that coincides with the audio signal. It sounds similar to a dirty volume control on an amplifier. It's only noticeable at low volume. It doesn't happen at high volume. It's like the circuitry is allowing some parts of the audio signal to pass but not others. I have been very disappointed with the quality of this unit. I sure hope it's not typical of Velodyne's quality.
The bottom line is I'd like to be able to fix the sub. Can anyone help?
