These brackets are decent but not compatible with Logitech Z906 speakers. The screw threads in the speakers are larger and there is no matching one that comes with this bracket. However, the biggest compatibility issue is that the brackets cover the speaker terminals. Therefore, to use them with this system, you will need to drill new holes and use larger screws. See picture for more information. Pros and cons of the mounts alone: + Sturdy plastic - probably holds more weight than advertised + Good angle adjustment - approx. 90 degrees horizontally and 15 degrees vertically (can be changed) - Must be taken completely separately from the mount, which consists of 5- 6 pieces - may be a puzzle for some - Must loosen the top screw (with a screwdriver) after assembly to adjust the angle - no thumbscrew/etc. - Most screws and bolts are visible after assembly, if only the speaker does not hide them. The included screws should be black to match the plastic, not the chrome.
