Review on 10PCS Speakon 2 Pin Male Plug Audio Cable Connectors - Compatible with Speaker/Amplifier - NL2 2 Pole by Christopher Bates

Careful, these are 2 pens but NOT! fits into a 2-pin socket. The reason for this is that a 4-pin will not fit in a 2-pin, not only because of the pins but also because of the different inner housing. This is a 4 pin package with only 2 pins installed. If you need a 2-pin connector for a bipolar connector, look for a crescent-shaped cutout in the center of the case. They work fine in a 4-pin package, so any claims that they don't work are false. However, the product description is misleading and should be clearer.
