4-Pack 4mm Banana Jack Binding Post Gold Plated Female Socket Plug Terminal Connector for Loudspeaker Amplifier (2pcs Red and 2pcs Black Rubber Ring)

These plugs are well built from good material. They are of an appropriate size that suits the back terminal connections for speakers. However, these are not screwed types, rather the driver cables have to be soldered at the openings of the plugs. Once soldered, they can easily secured to the back of the speaker crossover board with the supplied washer/nut. The banana plug receptors provide a stable connection with a typical banana plug with a distinctive click. These plugs provide a great value for improving older speaker terminals. If these are being considered for an amplifier output connections, the process may be possible but would be more difficult seeing that the terminal protrusion in the rear is quite short. These are better suited for speaker inputs.

Was looking for a replacement part for a name brand speaker, did a lot of googling and found this one. If is not exactly the same as the broken piece (2-3 mm shorter base post), but banana plug fits perfectly and the base post is the diameter I needed and long enough to fit in the speaker back wall. The part was delivered in a couple of days, replacement went smoothly. Worked great for my sound system!

Worked perfectly. Easy connection.

Great chassis-mount banana plugs for any project just be careful on how much you tighten the nuts because they can strip out. Other than that I recommend them highly.

Don't Buy These! 1) the socket is about 2/3 as deep as the standard banana plu. So the plug will not fit properly. To get than to go that far, I had to clear the burrs on the hole for a wire if uses as a binding post. Not to standards and the machining was like the holes were just punched out. Prro quality. 2) in installing it with hopes it might work, I installed it in the hole I had for it and used a nut driver to snug it up. The screw that goes through the hole broke right off! Not even tight with a tiny wrench, just a small nutdriver. Barely tight. SIMPLY A PORLY DESIGNED AND POOLY MADE PRODUCT ALL THE WAY AROUND.

These little jewels were just what I needed for my little stereo project. Easy to install and fit 4mm banana plugs perfectly.

I have a modified home music player i did myself. & these worked perfect for the DS18 sub to go with it. Didnt like the terminals the sub already had, & the stereo head had to be modified to be fitted with a pair of these, which all together just worked out perfect. My only recommendation is that when using these, use a second Nut when tightening them down. The nuts that they came with stripped to easy on the threadig on the inside of the nut. Other than that 100% happy with em

Feel a little cheap. Added some washers for More stability. Banana plugs are loose when plugged in. Would probably not purchase again, but in this instance, they will be fine for my needs.

Good product but of note the post only just makes its through 1/2inch MDF speaker case. If it was any thicker these would not be able to have the backing affixed.
