To repair/replace Utopia Be

I have built several speakers over the years and i would like to point out a few things:
The coil associated with a tweeter is extremely sensitive and can be damaged if you apply to much heat to the driver terminals.
There is a right way and a wrong way to do the soldering:
1. Do not use a soldering gun unless you want to order another tweeter. A soldering gun as opposed to an iron can but outs hundreds of watts of heat in a very short period of time.
2. Rather buy a cheap iron from radio shack $20. Tine i.e. pre solder the wire leads that connect eventually to the terminal.
Place a crocodile clip behind the drive terminal to absorb heat upstream of the joint. Use another clip to hold the tined wire in place against the terminal. Apply heat to the terminal 3-4 seconds, touch the joint with solder for a second, remove the solder then remove the iron. Blow on the new joint.
And ensure you mark the polarity of the wires before you move them. Nothing will kill the sound of a pair of great monitors and a driver connected out of phase.

Enjoy and good luck

All good advice. Extra Action has you all set. I recently repalced a tweeter dome for a friend on a pair of B&W's and had to solder the leads.

Note the position of the wires. If you can, take a digital photo of the old one.

When I unsoldered the old diaphragm I just heated it up a little and removed the wire. The leads had enough solder left to just heat it up and quickly add the new wire and blow on it without addign any solder. Esentially the same as Extra Action's advice.

Thank you all for your useful advises and tips, I took off the damaged unit yesterday. I will get the new unit in two weeks and will report back how it goes.

I got it repaired finally, everything is fine now, thank you all for your help.
