Default Attaching flexible leads to aluminum voice coil wires

I know that with the correct materials, equipment, and technique, aluminum can be welded, brazed, and even soldered. There are simpler techniques for plating and soldering the wire ends. There are conductive glues.

What do speaker mfgrs ike JBL use to electrically connect & attach flexile leads to a cone with flat edgewound aluminum wire voice coils?

The preferred method requires an ultrasonic solder pot to pre tin the aluminium wires which allows for the use of normal solders.Otherwise there are special solder alloys and fluxes such as Alu-Sol from Multicore that can be used,although some experience is needed to find the best technique to make reliable connections.
