Dome Posted July 1, 2003 Share Posted July 1, 2003 Just a few days ago I purchased a RC-3II. Today I noticecd some slight distortion in the corner of my TV. The closer the back of the speaker was to the front of my TV, the more distortion. Could there be something wrong with the shielding on my woofers? It is apparent on both sides of the speaker. If I move the speaker back a little on the TV, the distortion goes away, but could this still be causing damage somehow to the back of the TV tube? Thanks for your help, Adam Zeimet Quote Link to comment Share on other sites More sharing options...
easylistener Posted July 1, 2003 Share Posted July 1, 2003 I have heard of this problem before. The person with this problem never said what he did. I would call klipsch. Quote Link to comment Share on other sites More sharing options...
Malcolm Posted July 1, 2003 Share Posted July 1, 2003 Your speaker is unlikely to cause permanent damage to your TV. If the distortion goes away when you move your speaker, no problem. If it stays when you move the speaker far away, you have magnetized the shadow mask, it will probably go away the next time your turn your TV on and it goes through its automatic degaussing cycle. If for some reason this doesn't fix it, it can be fixed with a TV degaussing coil, a bulk tape eraser or sometimes even a refrigerator magnet. As far as there being a defect in your speaker, my guess is it is OK. Magnetic shielding used in speakers reduces but does not eliminate stray magnetic fields that will affect the CRT in your TV set. Some sets seem to be more sensitive than others. And moving the speaker even an inch or two may have a significant effect. You have found at least one location where you have no problem. I suggest you leave the speaker there. Quote Link to comment Share on other sites More sharing options...
amonteiro Posted July 2, 2003 Share Posted July 2, 2003 I had a similar problem. What I eventually figured out was that the speaker wire used for it was looped. This can cause a magnetic field. So make sure that the speaker wire is straight and not tangled up. Quote Link to comment Share on other sites More sharing options...
avman Posted July 2, 2003 Share Posted July 2, 2003 i suspect a problem w/the sheilding, and you should call/e-mail tech support at klipsch. this could cause damage to the phosphors in your tube. avman. Quote Link to comment Share on other sites More sharing options...
gtDark Posted July 11, 2003 Share Posted July 11, 2003 That's really funny that I actually ran upon this post. I too have had this problem when I moved my RC-3 II from below the tv in a compartment to resting on top the tv. I came home from work one day and the center channel was back in the bottom compartment and my roommates said they moved it because it was causing some interference. I was pretty incredulous because I knew that the speaker was magnetically shielded. Guess I was wrong though. Just shot Tech an email though. I also don't have a problem with too long/coiled speaker wire. Quote Link to comment Share on other sites More sharing options...
PhilMays Posted July 11, 2003 Share Posted July 11, 2003 It's the shielding. When I had a tube TV I had to place a piece of 1x lumber between the TV and speaker (RC-7) that provided proper sheilding. Quote Link to comment Share on other sites More sharing options...
gtDark Posted July 11, 2003 Share Posted July 11, 2003 That's BS IMO. I mean why should we have to do stuff like that (putting the 1by in between)? I mean if it says it's magnetically shielded I expect them to be magnetically shielded. Do you still have the wood there or did you talk to Klipsch and get a new speaker? I'm not going to say anything strong yet because Klipsch has always been great with no problems (with the exception of my ProMedia 5.1's). Oh well, we'll see how this plays out.

PhilMays Posted July 11, 2003 Share Posted July 11, 2003 No, I was able to remove the wood. I now have an HD projectionb TV, no tubes no problem. Quote Link to comment Share on other sites More sharing options...
Malcolm Posted July 11, 2003 Share Posted July 11, 2003 Lumber will not provide any shielding. All it will do is move the stray magnetic field farther away from the TV. Quote Link to comment Share on other sites More sharing options...
mopar dave Posted July 14, 2003 Share Posted July 14, 2003 i to have a tv problem that i relate to my home brew cornwall's. i attemped to turn on my tv the other day and it was dead. i tried manual as well as remote, nothing. i checked the plug, it seemed ok, so i pulled the back cover off and with a volt meter check both sides of the fuse and found 117.5 volts, but it(panasonic 32") will not turn on. the tv is only 6 years old. the cw's set about 3' away on each side. do you think the cw's are at fault? i never had a problem with this tv bafore. dave Quote Link to comment Share on other sites More sharing options...
DRBILL Posted July 14, 2003 Share Posted July 14, 2003 DAVE, Check and see if the city installed new stop signs at your corner. This is often the cause. Smiles, DR BILL Quote Link to comment Share on other sites More sharing options...

gtDark Posted July 15, 2003 Share Posted July 15, 2003 Adam, have you heard from Klipsch yet or figured out a solution? I sent them an email a while back and still haven't heard anything back yet...I need to start sending read receipts with my emails . Quote Link to comment Share on other sites More sharing options...
Dome Posted July 16, 2003 Author Share Posted July 16, 2003 Here is the email that Klipsch support sent to me: ---------------- All of our shielded speakers are tested before leaving the assembly line. It is very unlikely that part of the shielding may have been dislodged due to shipping, but something that shouldn't be ruled out. I would suggest returning it to your dealer and check it against one they may have in stock or with one of their TV's. The Gauss measurement on this speaker is actually below our standard of 3 and this is taken from the bottom and top of the speaker. The higher the number, the greater the possibility of color distortion. We have found some TV models are more susceptible to magnetic fields than others and Sony flat screens are the easiest effected by this. The larger the flat screen, the more susceptible. But there have been a few other flat screen TV's that may be affected as well. There are other speaker manufacturers experiencing the same problems with one or more different brands of TV's. You may want to position the RC-3 II on a shelf above the TV, this should help. ---------------- It did take them a little while to respond. However, I responded to this email, and their second response came pretty fast. I just moved my speaker back a few inches and do not notice the distortion on the TV anymore. By the sounds of the email, they cannot 100% eradicate the stray magnetic waves from all the drivers (hence the gauss rating). Quote Link to comment Share on other sites More sharing options...
Guest BobG Posted July 21, 2003 Share Posted July 21, 2003 No "shielded" speaker has 100% control of stray field. Not Klipsch nor any other brand. Quote Link to comment Share on other sites More sharing options...
