Where can I get a set of Harmonic Technology pro 11 speaker cables re terminated?

Some banana connectors have a little wire running up the prong. Maybe all you have to do is pry it up a bit, like with a small blade screwdriver. Good luck!

Try WBT, the offer spades or banana that don’t require soldering.they have little Hex Head screws that are tighter to a sleeve that secures the connection. They also offer tool kits for making these connections.

I would figure out who manufactures the spade terminal. They have the specific requirements as far as type of crimp tool to use. Maybe the crimper is inexpensive to buy and do it yourself. Good luck!
