Hi,
I have a klipsch SW-15 sub which I have had since new. It is working but has a strange problem, when either me it my wife get off the couch the sub makes a few popping sounds. That is the only time I can simulate this problem, other than that the sub plays fine & loud. Could static being generated by stepping on the carpet cause it or could it be a problem with the drivers being so old that maybe they are due to be re-coned? Anyone experience this or have any ideas? Thanks, Rick
