ghostmech Posted June 6, 2011 Share Posted June 6, 2011 ...and cause a descending bumping sound thru the speaker when I shut power off, either by the Onkyo 905 or via the switch on the back of the sub itself. The other 12D does not do this. If I had to guess, it sounds like a capacitor is bleeding down power after shut down but yet, the other sum does not. Any ideas why this is happening? Is it detrimental to the sub? Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted June 6, 2011 Share Posted June 6, 2011 Some subs make a pop when you turn them off. You might as well just leave them on all the time. They draw virtually the same amount of power in the 'On' position as they do in the 'Auto On' position. Quote Link to comment Share on other sites More sharing options...
