Arroyner 4Pcs 3-Inch Speaker Box Terminal Cup DIY 2-Way Speaker Box Terminal Binding Post Round Spring Cup Connector

Quality is good.

These circular speaker wire connectors are exactly what I needed to improve my sound system setup! They make connecting speaker wires so much easier and more secure, giving me a flawless, high-quality connection every time. The design is compact and durable, and they fit perfectly with my existing wires and speakers. Installation was a breeze—just slide the wire in, and you're good to go. The connectors also ensure no signal loss, so my audio quality is crystal clear. If you're looking to streamline your home audio setup, these connectors are a must-have. Couldn't be happier with the purchase!

Great value, and they work. Easy install. Two issues. One, the terminals are super thin. Be careful when installing the spade connectors. Two, plan on buying the banana connectors if you intend to disconnect/connect often. It's a PITA to tighten the lugs due to the size and angle of the hand nuts.

These terminals are ok for the price as far as quality goes. Make sure the hole you cut is as accurate to the minimum size required to fit the terminal cup in or you’ll risk not having enough wood to drive the screws straight in. I had a hole saw that was on the larger size of the required size and had to angle the screws slightly outward to get a good bite on the threads. This problem was on me. My only complaint is there was only one terminal cup completely assembled out of the 5 in the bag. All of the rest of the parts were simply thrown in there loosely but thankfully everything was there and I had one sample of how to assemble the other 4.

Works perfectly
