Hi, 

I recently purchased a couple of speakon chassis's, but I don't find any instructions on how to solder these. Anyone here that has experience with them and want to share?



Cheers,
Nathan

By instructions do you mean what pins for what or actually how to solder the joint successfully?

We normally heat up the metal part of the speakon socket with the soldering iron and fill it with solder. After that we heat up the end of the wire and put some solder on it too. Lastly, put some heatshrink on the wire, heat up the metal part of the socket again, put the wire inside, let it cool down and shrink the heatshrink over it :)

Ok

First you will need a suitable iron. These connectors have quite a substantial thermal mass, and very important in making a good joint is being able to get sufficient heat in quickly as slow heating will damage surrounding insulation.

A suitable iron would be around 70w, or the equivalent if using a gas catalytic iron.

Choose a bit with a suitable end, thicker ends with greater surface area will get more heat into the joint quickly. 3.2mm bevel end is a good general purpose option. Bit temperature will depend upon the solder used, so check specifications here.

Preparation: strip back the insulation on the cable ( tri-rated cable is ideal for internal cabinet or rack wiring) to the depth of the solder bucket, around 8mm. Twist the strands of the conductor neatly, then tin the exposed conductor by first wetting the iron bit, then applying the bit to the centre of the exposed conductor and then apply sufficient solder between the iron and conductor so that the whole surface of the conductor is covered by a thin layer of solder.
Then apply the iron to the solder bucket of the connector and wet the contact with solder
Bring the conductor into contact with the connector contact and apply heat with the the iron to form the joint. Add sufficient solder to fill the joint but not so much as it overflows the bucket. Support the joint/cable until the solder has solidified, this should just be a few seconds. Any movement before the solder solidifies will cause a poor and weak joint, often known as “dry”. A good joint will have a fairly bright finish.

Then repeat!

I should add, on the subject of insulation such as heatshrink or hellerman sleeves,

The need for this depends on the quality of your work, and being careful that no strands are loose. 

Make the joint well and, provided that it is in a place which can not be touched or come into contact with another conductor then insulation will not serve any purpose. I don’t know how many connectors i have terminated over the years but it will be in the 10’s of thousands and not once have I insulated a contract in this manner.

A Lead - Tin Solder 60/40 type makes soldering a lot easier than a lead free - and melts at a lower temperature.
As said above, the best way is to tin / add fresh melted solder to both parts, and then melt both parts together to make the joint. Adding a little more fluxed solder at that point helps with heat transfer from the iron & solder flow.
