Rock-Solid Mounts with Flawless Adjustability
Size: Standard--black, Size: Standard--black
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?

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.

Almost perfect, absolutely fit for purpose, and a great value
Size: Standard--black
These are really, really close to being five stars, but because of my OCD tendencies when it comes to things being true and level, I can only go four. The way these mounts are made, speakers rest inside and on the inner surface of the L-shaped adjustable side brackets, and not on the large metal plate between them. Leveling on the fore-and-aft plane can easily be handled via the adjustment nut on the bottom of the bracket. But there is no provision for side-to-side leveling, so if the manufacturing of the side brackets is not within tolerance, you'll wind up with a speaker that's ever-so-slightly wonky...which is the case with ONE of my mounts. The bubble is still between the lines, but it's kissing the left line. Most would not care about this, and I'm not too bummed about it, but I am able to see that much out-of-true with the naked eye. It's not enough to pursue any kind of remediation, because the value on these really is awfully good. They are solidly built, easy to install, and easy to adjust. The manufacturer is apparently improving the product as they go based on feedback, as some issues that have vexed other owners have not been a problem for me, such as the wall plates being or coming loose (the design now ensures they stay put once pushed back to the wall), or the adjustment nut and bolt rotating freely and not staying tight (the ones on mine are great and function as intended). For the price, these are really hard to beat, and I have a feeling all the mounts like this with the different oddly-named brands are made in the same factory. That being the case, get the cheapest ones, and the day I bought mine, these were those.
