tcb Posted April 15, 2004 Share Posted April 15, 2004 Ok,here is the problem.The corner where stay one speaker have 2 different levels,I mean is a few inches portion where I guess cover some electrical cables.That speaker even without any conection to amp,capture a hum/electrical buzz,when is in the corner.If I pull it out about 5 feet,the buzz is out,push in the corner back,the buzz is on again.If I conect back the speaker cable to amp and turn on the amp,the hum/buzz decreased dramatic.If I turn off the amp,the hum increased again.This problem I have is only with location and not with speakers,because I try to swap them from a corner to other one and had same problem in that corner.My question is what can I do to isolate that wall portion or how about to try shock ferrite on the internal cables on crossover,midrange,tweeter ???Hope somebody will understand with my poor english.....Kindly appreciate any help. cheers Mario Quote Link to comment Share on other sites More sharing options...

Q-Man Posted April 15, 2004 Share Posted April 15, 2004 Maybe, just maybe lining the corner with low carbon sheet metal will isolate the magnetic field. Can you re-route the wires in the floor that are causing the problem? Quote Link to comment Share on other sites More sharing options...
Guest klipschomatic Posted April 15, 2004 Share Posted April 15, 2004 mU-Metal sheeting along the offending wall or floor would do the best job at elongating the electro-magnetic fields so the extremely sensitive K-Horn doesn't pick them up. There may be a grounding strategy you could use, but I am not sure at what would be safe to do. Ferrite cores would be worth a try. Quote Link to comment Share on other sites More sharing options...

lynnm Posted April 15, 2004 Share Posted April 15, 2004 I suspect that that boxed portion is a cable race. Do you by chance live in an apartment buildin and further does that building have an elevator ? Quote Link to comment Share on other sites More sharing options...
