How to hang large speakers on the wall.
The exact method required here depends upon your speaker.
I used the velcro and recommend it however your speakers are 2x heavier than mine monitor 40 s.
Another suggestion might be to buy a large shelf board from loews home depot etc along with 4 l brackets decorative or otherwise.
Tv mounts are more sturdy.
How to position your speakers perfectly.
A threaded stud basically a screw shank with no head makes the connection between the mounting bracket and the speaker itself.
Install the speaker.
This is the best solution if there are threaded holes in the back of the speaker.
If your room is a rectangle the speakers will ideally face the length of the room so place your desk by the shortest wall.
Reattach the mount arm to the ceiling plate if required.
The value of the life of any single person listening to your hanging loudspeakers is far greater then every other element in your audio visual system.
Safely hanging your speakers is more important then where to hang them how good they sound or how the room looks when they are in the air.
Attach an extension arm to the ceiling plate if needed.
Cut the board to size and use two l brackets one on each end.
For relatively heavy over 10lbs and when you need to tilt speaker you can use lcd tv mount.
