Got these for my recently acquired 3010i and 3090Ci arctic white speakers to sit on.Not a problem for me that they didn't come with screws to attach them to the walls as there are too many variables and potential litigation issues ("I attached them to a piece of paper using the screws provided and they fell off giving me concussion.." etc). Just make sure you get the right screws AND JUST AS IMPORTANT the right plugs for the weight of the speakers (5/6kg in my case) and the wall the brackets will be attached to (masonry and brick in my case).Also, these are specifically for the 3010/3020/3090C or 3010i/3020i/3090Ci speakers. NOT FOR ANY OTHERS INCLUDING OTHER Q ACCOUSTICS RANGES (i.e. the 2000 series or 1000 series etc). Therefore, no compatibility issues for me that some others have found.The Good1. The design means the brackets are almost invisible, which gives a nice floating look. The speakers are taller and wider than the plate that attaches the bracket to the wall and much deeper than the bit that they sit on, which means looking at the speakers dead on all you really see is the small bit underneath, which is tidied up and colour matched using the slot on cover that comes in the box (see picture). I do wonder if the design came at the price of some practicality/usability though (see 'not so good' below).2. They’re not flimsy and they support the speakers fine. The core of the bracket is strong metal, and they are sturdy enough to support the speakers, which at 5/6kg is a key consideration and no mean feat. Considering how deep the speakers themselves are, the bit that they sit on is really quite small. As such I was a bit sceptical, but they proved me wrong.The not so good1. Attaching the speakers is a bit of a pain. 90% of cases will be a 2-person job. As others have said, attaching the speakers to the brackets is a real bear. This is almost exclusively down to the weight of the speakers, but then I would argue that if the speaker that a bracket is designed for is heavy, then this should be taken into consideration by the design and the impact this has on the method needed to attach the speakers. I am by no means a designer, but attaching the bit the speaker sits on to the speaker first and then attaching both to the actual bracket in a way that doesn't require you to hold up the speaker at the same time as trying to screw something into it strikes me as easier than what they have done here (upward pointing bolt that screws directly into the speaker). I was able to do it myself only because the speakers were not high up, so I could support/hold the speaker in position with my chest while I cursed and fumbled around underneath trying to get the Alan key to find the hole in the bolt and tighten it, which felt like it took forever!2. Can’t use Banana Plugs. I got right angled ones specifically (where the wire attaches underneath), but the short amount of travel the design allows means that even these unfortunately can’t be used if the speakers are to be level and not pointing down, which if you’re using them for the front speakers (i.e. L, C & R) is going to be almost always.3. Very limited angles. Side to side movement limited and pointing up is pretty much non existent. The diagram in the product description (and also on the box) shows the speaker can be angled 45 degrees down, though I have to ad I’m not using them like this. It also shows side to side angling being possible up to (in my speakers case) 40 degrees. Having played around with the bracket a bit, the mechanism does allow the bit the speaker sits on to move from side to side (I didn’t measure how much) BUT ONLY WHEN IT IS ALL THE WAY FORWARD, i.e. pointing 45 degrees down. As you bring it up and closer to the horizontal, the lateral leeway disappears due to the design and I can’t for the life of me see how side to side movement is possible in a level or close to level position. I have gone back to Q acoustics about this as I can’t see why this would be the case. Ideally speakers should be at ear level and in a lot of cases pointing at the listening position, so having a bracket where this is only possible when the speaker is pointing down 45 degrees is a bit mystifying to me. The only way I can see how to do it is for the bit the speaker sits on to point forward, but the speaker itself sat on it at whatever angle is required, which seems a very odd design choice to me, especially given the depth and weight of the speakers in question. Finally, it’s worth pointing out that angling the speakers upwards is not really possible. To be fair, it doesn’t say anywhere that it is designed to allow upward movement, but still worth noting. I managed to get a very slight upward angle, but best to assume its not possible, just to be safe.
