I have an Elac tower system with an active subwoofer. The subwoofer is on auto mode. When the amplifer (demon) is on standby mode, there is a slight thump like sound emanating from the subwoofer at infrequent intervals. The thump sound is mild. The active subwoofer light is continues to be on even though it’s on auto mode.
My questions are:
Is it a defect?
Will it damage the subwoofer?
Is it recommended to power off the subwoofer when the amp is on standby mode? Otherwise the speaker system plays awesome.
