Good quality, worked great for my custom powered sub built

cumplen su funcion, sin embargo el tornillo que se utiliza para fijar el cable podria ser de mejor calidad y proporcionar una mejor retroalimentacion de como se esta fijando el cable, en lo particular estañe el cable

Good quality

These look good quality and are easy to wire up with a small screwdriver.

Took me 5 minutes to prep the wire ends and screw into the appropriate connections. I had a spool of 12AWG cable lying around and needed a Speak On connector to go from my amp head to my cab for my MarkBass Little Mark III. These work perfectly. Twist and lock - and in future, when a cable gets damaged I can just re-do it ;)
