Hi, I read the user manual for my new XL but it's a little confusing as to what I need to buy to wall mount my soundbar. Can you please clarify what I need to buy and where I can get it? Thank you!

Are you mounting it flush to the wall? If so, you use the keyhole mounts on the back as indicated in the manual. The only part of the hardware that relates to the speaker is the head of the screw, which is also specified:

- #10 pan head screw to fit the mounting keyhole on the back of the speaker

How that screw is attached to your wall depends on your wall. If you are unsure how to attach to the wall, consult a professional installer - or just go to the local hardware store and tell them your wall type and they will direct you to the correct hardware.

Do you know what the dimension is between the 2 mounting holes on the back of the Array and the Array XL? I have 2x4's mounted to my wall for my current Leon soundbar and would like to know if it will work for either of these bars? Thank You.

The two threaded inserts on the back of the SuperCinema 3D Array XL are 10.94 inches apart. (The two keyhole slots are 20.47 inches apart.)
