Speakon designs Several small projects for speakon speaker plugs

Speakon dummyplug Just a simple dummy plug to use when the speakon plug is not in use to prevent dirt entering the female plug.

demo speakon chassis part A very basic but true to size speakon chassis plug. You can use it in your design to do a sanity test and check for clearances.

Speakon splitter box At some point it is nice to be able to use just 4 wire cable with a speakon 4P plug to run a line to some passive speakers. At that spot you can use a generic splitter or use this box for it. There are 2 versions: 1 with the space for creating a 'through connection' and one with just space for splitting the 4 wires in 2 speakong plugs.
How you wire them up, is entirely up to you, i used the bigger one to be able to attach 2 speakers, and have the 'through connection' be exactly that: a through connection so i can add a second (smaller) splitter in parallel.
I did entertain the possibility to add a switch in the large box to be able to switch from parallel to serial connection, but i never really needed that option. If i ever do, i'll create a box with a hole for one.

The design is made for M3 x 15 sunken head bolts and using M3 threaded brass nuts that you can melt in place.

You will need a decent soldering station for it that packs a bit of watts, soldering the 2.5 mm2 wire to the tabs of the speakon plugs requires a lot of heat!
