Absolutely fantastic mounts! I couldn't be happier with this purchase. They are currently holding my 12lb surround sound speakers on the wall, and I have complete confidence in their sturdiness. They feel incredibly solid and well-made. Installation was a breeze, and the range of motion is a real game-changer. Being able to swivel and tilt the speakers has allowed me to perfectly angle them towards my listening position, which has made a huge difference in my surround sound experience. On top of the great functionality, they have a very sleek and clean look. The built-in cable management is a brilliant touch that helps keep everything looking tidy and professional. If you're looking for a reliable, adjustable, and great-looking set of speaker mounts, look no further. These are top-notch, and I highly recommend them!

Great product!

Size: Standard--white, Size: Standard--white

Very sturdy and great value for money! Speakers fit perfectly. You can adjust the width and tighten around the sides of the speaker so they’re not loose on the platform. Offers proper stability for the speakers, they will not fall out of the wall if they’re installed correctly and not overloaded with weight. I have the Edifier R1280T speakers mounted and they’re roughly 10-12 pounds each. **My only complaint which was not a big deal to me** As other people have mentioned, the white plate that hides the screws on the wall is not attached to anything. It was just hanging there loose with a gap between it and the wall, but I got these clear double-sided tape circles to adhere them to the wall and it worked !!! Very quick and easy solution. Maybe the seller could include a few clear stickies in the package moving forward?

Ideal speaker wall mounts

Size: Standard--black

These speaker mounts were better than expected for the price. The mounts hold the speakers securely also tilt and swivel to get the sound where needed. Well thought out design, easy to mount, looks great also. Mounting hardware was included. I would purchase again.
