I got a set of these today and was ready to treat them like a surgery after reading this. I managed to make a couple of mistake so hopefully I can share some insight on how not to make the same mistakes that I did. When you pull the tweeter horns out after removing the screws, there is a rectangular rubber gasket that hides the circular cutout in the wood. Carefully tilt the horns out, and have a pair of needlenose sitting on top of the speaker to remove the connectors in a side-to-side motion. I marked the magnet on the back for the wire coloring. Getting the old diaphrams out is easy, then when you re-install the new titaniums remember this ... the domes are not just paper-thin, but like an eyeball. There is a white plastic on the diaphrams that I assumed you take off, they have a bit of a sticky substance underneath. When I took the plastic off, I realized that I had dented the dome, and couldn't understand how I did that after being so careful. I had to cup my hand around it and use my central vac to pull it out, but ... so if you're anal enough to replace the tweeter than you know it's been compromised. Being extra careful on the second one, I still managed to put a very small dent in it, but at least I figured out where I screwed up. If you pull the white plastic off, I think you would be better off pulling a corner up and cutting it, and then pulling it away from the dome. It's extremely fragile.
I'm going to buy another set, they are very reasonable. But even my tweaked ones sound better in my opinion, even after my Homer Simpson ... Doh! ... moment(s).
