Review: These terminal cups are great quality, especially for the price. The plastic housing feels strong and fits cleanly into a standard speaker cutout. The banana plug connectors grip tightly, and the screw terminals make wiring simple, no soldering needed. Installation was quick, and the overall look is clean and professional once mounted. The connectors handle solid-gauge wire easily and provide a secure, noise-free connection. I’ve used them on a couple of DIY speaker builds, and they’ve performed perfectly every time. If you’re building or repairing speakers, these are an easy win, affordable, well-built, and reliable. Excellent value for anyone doing custom audio work.
Review: The terminal cup on my 10" sealed Bbox subwoofer enclosure broke so I needed a replacement that fit a 50mm round hole. This was the only brand I could find online in that size. I received the pack of 2 terminal cups from Mo-gu within 2 days. I was impressed that they came with a rubber gasket and they were not as flimsy as others have said. They terminal screws tightened down on the speaker wire tightly and the screw holes lined up with the existing holes perfectly. It came with 4 black wood screws but I reused the old screws since they were slightly thicker.
