InFlux Posted October 28, 2005 Share Posted October 28, 2005 I have a KLF-C7 that was damaged in shipping. Both bucking magnets came loose and wreaked havoc inside the speaker cabinet. Fortunately the horn and its driver are fine. Both woofers were damaged, so I have replacements ready to go in. The replacement woofers do not have the bucking magnets attached & I want to reuse the old ones. How do I attach the bucking magnets to the replacement drivers? Do I simply hot glue or liquid nail the bucking magnet cap on? Quote Link to comment Share on other sites More sharing options...
redtop Posted October 28, 2005 Share Posted October 28, 2005 Sorry to hear of your shipping issue... When I attached bucking magnets to my custom KG 3.5 center channel, Klipsch tech support recommended I use a two part epoxy and clamps. Worked like a charm. The hardest part was getting those darn magnets into the position where they cancel each other and clamped down. [] Quote Link to comment Share on other sites More sharing options...
DrWho Posted October 28, 2005 Share Posted October 28, 2005 Just to stress the point....be sure the bucking magnets are repelling when they're being attached. Once the epoxy sets you won't be able to get them seperated (unless you ship them again, lol) and it would suck if you got it backwards. Also, be sure that the previous bucking magnets are still fully charged. Magnets don't like being bounced around and knocked on so be sure they've still got enough flux to cancel out the magnets on the woofers. It's not a super big deal but I have seen it once where a magnet completely lost all its magnetism from being dropped. Perhaps clamp them to the back of a woofer and see if it screws with your TV before gluing. Quote Link to comment Share on other sites More sharing options...
michael hurd Posted October 28, 2005 Share Posted October 28, 2005 Epoxies can be softened with heat, however too much heat will destroy the magnet. ( weaken it ) You may try another method to remove the bucking magnets, using chemicals. http://www.crosslinktech.com/FAQ/Removing%20cured%20products.htm Quote Link to comment Share on other sites More sharing options...
InFlux Posted October 28, 2005 Author Share Posted October 28, 2005 That was a lot more feedback than I was expecting. Thanks guys. Epoxy sounds like the ticket I was looking for. I really do not expect the magnet to get warm enough to cause problems. Dr. Who, you've got me thinking about the polarity. The bucking magnet itself is still glued inside of a sleeve that slides over the woofer's magnet (pretty slick design). I don't think I'll have any problems - but I will double check. Thanks for the heads up. My 6.1 configuration will be complete and open for your enjoyment on Sunday night, come on by! Quote Link to comment Share on other sites More sharing options...
michael hurd Posted October 28, 2005 Share Posted October 28, 2005 If I understand correctly, the shielding cup with bucking magnet inside came off the woofer? If so, then there is no way you can screw it up, just clean the new woofer magnet, and epoxy away. Edit: get the 5-minute stuff that comes in a dual syringe, that way you can't mess up on the ratio - epoxies are sensitve to the quantity of resin to hardner. You can mix it on a piece of tinfoil or a paper plate. Quote Link to comment Share on other sites More sharing options...
InFlux Posted October 31, 2005 Author Share Posted October 31, 2005 Well, yes, I thought they both did... Upon closer inspection yesterday, I discovered that only one came off completely. The other woofer's cap fell off, but the magent was still glued to the woofer. For future reference, don't try to pry the magnet off. You will probably crack the magnet... Oppps. Time to find one replacement. Quote Link to comment Share on other sites More sharing options...
