Can someone help me with a popping sound??


Hi all,
I'm having problems with a popping sound (sounds like rice cripies cereal) coming from my speaker & I think I've narrowed it down to possible interference from my subwoofer. My subwoofer seems to be emitting an electrical hum. Is it possible the hum is being picked up through my speaker cables & sent out through the speaker? The popping is only coming through the speaker closest to the subwoofer. If the culprit is the subwoofer, does anyone have any suggestions to fix this problem? I've got a picture posted of the speaker & subwoofer in the "system" portion of Audiogon, if you think this may help. I've straightened the cables out & separated them the best possible (better than the representation in the picture), but I don't have much room to work with. Any suggestions would be much appreciated. Thanks

I've disconnected the subwoofer cable & P/C. Now I've got an high pitch frequency coming out of both speakers. I've never had a problem like this. I turned the preamp off/on & the pitch is gone. I just purchased a new "slightly used" Sonic Frontiers Line 3 SE & added it to the system. I also added Analysis Plus Silver Oval Cables & used them for about 30 hours so far. I don't think the problem lies with the speaker cables because I've swapped them out & the problem remained. I'm leaning toward the tube preamp, but since I'm new with tubes I really don't have a clue. I would appreciate more suggestions, please.
Since you are using tube pre-amp, there is a very high chance that one or some of the tubes inside the pre-amp have problem.
Change all the tubes and see what happen.
Also Sonic Frontiers support is great and the tube sets are cheap! They moved last week but give them a call or I would suggest RAM tubesets.

I think you will be stunned by the upgrade in tubes.
Dsiggia: Since you didn't say otherwise, I'll assume that after you removed the sub (and after you switched the system off and back on to get rid of the whine, which I'll treat as incidental and isolated for the moment) you found your noise to still be present. Taking for granted right now your conclusion about the speaker cables, you should go ahead and follow the rest of the regimen I suggested above to try and nail down the problem...
