murrots Posted July 16, 2013 Share Posted July 16, 2013 I'm going to buy the rf-52 home theatre set and wanted to know if all the speakers are magnetically shielded. Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted July 17, 2013 Share Posted July 17, 2013 Call Klipsch, but something tell me that the bookshelf and towers are not shielded like the center channel. With flat screen TV's, it is not an issues. What are you concernd with damaging? Quote Link to comment Share on other sites More sharing options...
murrots Posted July 17, 2013 Author Share Posted July 17, 2013 Thanks. I was concerned about a led lcd tv, but after some more reading I found out that speakers only affect old tube style tv's. Quote Link to comment Share on other sites More sharing options...
moray james Posted July 18, 2013 Share Posted July 18, 2013 http://www.klipsch.com/rf-52-ii-floorstanding-speaker Makes no mention that I can see so not likely. Are you running a tube? Should not be an issue. Best regards Moray James. If you want to know pull the terminal cup off the back an look will take you a few minutes an you will know. Best regards Moray James.

Mongo171 Posted July 19, 2013 Share Posted July 19, 2013 From what I was told by Klipsch many years ago, the shielded speakers have an extra magnet glued to the speaker magnet to eliminate the the magnetic field of the speaker. Quote Link to comment Share on other sites More sharing options...
moray james Posted July 19, 2013 Share Posted July 19, 2013 What you are describing is called a "Bucking Magnet. While this can/could help with some flux issues it is not a shield but it can help to direct flux. Pole material saturation level is an improtant consideration when using a bucking magnet, if the pole is not saturated then a bucking magnet will help but if the pole pices are at or near saturation then it will not help at all and may even make matters worse as far as stray flux goes. The shield has to be made of a ferrous metal cup which encapsulates the magnet. Because iron and steel are highly permeable stray flux can more easily travel through the metal than the air and so stray flux is contained. Hope this is if interest. Best regards Moray James.
