Question: Does anyone have experience using these mounts with Audioengine A5+ speakers?
Document: Well designed, very sturdy, they hold the speakers securely and look good on the wall, especially holding my Audioengine A5+'s!
The universal design of these mounts allowsthe placement of most bookshelf size speakers.They are very solidly constructed, and whenproperly installed can hold a substantial load.These mounts are fairly easy to assemble, andhold the speakers in place very well. The rubbergrip strips provided are a little thin and may notsuit some speaker cabinets that have sides witha curve or angle to them. That can be easilyresolved using commonly available adhesive weatherstripping cut to length.
Mounted a pair of Polk monitor 30 Speakers using these.The speakers are not small and this unit accomodated it easilyand supported the weight just as well.
Very happy with these wall stands, I am using them with 8 lb bookshelf speakers. They are a bit large, but well made and I have had no issues whatsoever with them. The white colour blends in well with the wall and installation was a breeze. Would definately purchase again I need more.
You can adjust the angle, the tilt - everything has been considered.As others have noted, the manufacturer recommends fastening the speakers with the help of screws, which is not a good idea. Since i don't plan to remove these speakers any time soon, I ended up using industrial grade velcro between the speaker and the clamps.
Using these to hold up fairly small bookshelf speakers (Polk Audio T15, ~7lbs each) and installation was quite simple. I have steel studs that I wasn't able to drill into so I used LePage No More Nails mounting tape to affix it to the wall. I used one of the provided screws to give it a bit more reinforcement into the drywall and it seems very sturdy. Great product!
Impressed with the simple design of the adjustable clamps that actually hold the speakers. Based on a few other reviews that mentioned the speaker falling off, i decided to play it safe and mounted the speakers without any tilt to avoid using the small screws that connect the speaker to the clamps (in addition to the basic clamping mechanism). If you are OK with using the small screws (and hence poke holes into the speaker) tilting should not be an issue either. The wall cover is definitely a plus.
I have been using these brackets for about a year now. I am using them with a pair of Polk Audio RTi4's.
Easy install, sturdy mounts that can easily hold my PA TSi200s.I've tried other mounts claiming to hold up to 33lbs from monoprice that bent at the weight of the speakers.These solved my problem and look great. Feel very secure.
The set of bookshelf speakers that these are holding, aren't the heaviest in the world. So I was semi-turned off that the mounts were so expensive. After I got the mounts installed, I was able to put more than enough weight on these. I now consider the price to be fair, considering the quality of construction.
Answer: Yes, they work great!
