I just bought a pair of Klipsch Forte II, which are unshielded. I can't get them near the TV so I've ordered bucking magnets from Klipsch. I went to Home Depot expecting to pick up some 5 minute epoxy. I saw the 5 minute epoxy but I also saw something called metal epoxy. I'm not very "epoxy literate" but I'm assuming the metal version is stronger. My question...is the metal version the better choice for attaching the bucking magnets? I want the strongest, longest lasting stuff I can get. I assume that would be the metal epoxy but I want to make sure it's the right product for this application. BTW, if anyone has any tips for this I'd appreciate it. I've never opened a speaker so I'm a complete DIY newbie. Thanks!
