By the way, there is no crossover between the midranges and the tweeter. There is a step-up transformer to supply the necessary voltage. The tweeter is a bit of a pain to replace, but not that bad. The biggest problem I had was the bag of polyolefin flakes has a very wide mesh (at least on the Ref 3.1s), tears easily and the flakes leak out, making a mess.
Here are the steps:
Remove the screws holding the back plate on and remove he back plate.
Carefully move the bag of flakes out of the way to gain access to the screw for the top ball and the tweeter wires
Remove the allen screw that holds the top midrange and ball.
Carefully pull the mid-range wires through to give you some slack to move the ball and midrange out of the way.
Remove the top plate of the tweeter
Inside the stalk, cut the tweeter wires. Make sure you leave plenty of slack from the transformer.
Remove the tweeter and pull the wires through.
Insert the new tweeter and thread the wires through the hole in the stalk. This may take some time as the hole is covered with RTV to provide a seal.
Put shrink tubing on either set of wires (from the transformer or the tweeter.
Solder the wires from the transformer to those of the tweeter.
Use the soldering iron or a heat gun to shrink the tubing.
Replace the tweeter top plate.
Replace the mid-range ball and pull the mid-range wires back into the stalk.
Screw in the mid-range allen screw.
Put the bag of flakes back in position
Replace the back plate and screw it in.
