Its well the Rule to have THE tweeter at ear level?
I use to listen music standing not so much sitting, so why there is not speakers stands for 2 meters or 160 cm at least?
I can not pu it on wall, to much bass, and My wall is “hallow modern wall”
You could make or have a set of tall speaker stands made by a local wood or metal worker. You might also try just adding some blocks under the front of the speakers to tilt them back.
Maybe you could try a stack of hollow core cement blocks or stackable milk crates to see if you like the height.There should be a few simple ways to try it out using the local hardware or big box store (Home Depot or Menards type stores)
