The second option to be able to angle my center speaker up. Should be good enough?
My set up is below. I was hoping to put the center speaker at the top level of the stand but I realized that mounting the TV would make it too high given the short viewing distance. I figure if it's going to be at the second level after some re arranging that I will need to angle it up.
They should work if you know 4 degrees will be the ideal angle to point the drivers at your listing position. A slightly more flexible (and more expensive) option is to buy a package of Auralex MoPads, which have a 4° wedge and two smaller 2° shims.
