4-Pack 4-Pole Speakon-Compatible Twist Lock Adapter Connectors, Professional Audio Plug for NL4 Series, Amplifiers, Speakers - Heavy-Duty, Secure Locking, Stage & Studio Use

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

Did the job I needed them to do sturdy tight grips for cables

Item as described by seller. Arrived promptly as stated and did the job it was required to do.

Terrible cable would not stay when screwed down

Not much to say, You get exactly what's promised, they work perfectly and saved about £80 - £100 vs buying a pre-wired connector. Used on Rel- Q150E subwoofer. thanks

Screw connector is different from images. Have to leave wire 3 times longer than usual. PITA.

Great

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

Excellent, do the job. Easy to hookup.

Good quality

Unlike what some others have posted these work very well. You must first back the screws out almost all the way before inserting wire & then tighten very tight in order to hold wire. I used the same gage wire as the others did that claimed these didn't work but they worked beautifully for me. They were compatable with my Behringer NX3000d & I suspect they will be for others as well. These don't come with any cable.

Worked very well, easy to install, fits perfectly
