About this 3D model

This is the stand for Anker SoundCore Speaker that is popular on Amazon. You can change a speaker angle, 30, 45, 60 degrees. Maybe 0 degree. So the sound from the speaker is facing toward your face. There are two types of the stand. One is a mass, another is a shell type. The width is enough to push the power switch that plased top of the speaker. Sorry I don't understand about sound quality this stand influenced. Thanks!
