4 Pole Speakon Loudspeaker Socket

The datasheet says this will fit 6.0 to 11.0mm cable OD, but the clamp is loose on an 8.0mm OD cable. Without good clamping action the solder joints are likely to fail. Need to add sleeving to make clamp work.

This is a really good item. Obviously not Neutrik, however it does the job and at a very good price.
I use them on patch leads to convert different style amplifier output connections to speakon and these are perfect for the job.
