@ OP -- If you are looking for the realistic natural sound and the speaker that reproduces the original music, check below information.
Say "hello" repeat with below spkrs sounds and try hear your voice and speaker sound together.
When you listen a audio system at the show and people talk a lot and you want to say "please shut off. Let me listen to the music." Right. Human can’t listen to a human voice (natural sound) and audio music (electronic sound = un-natural sound) together.
People go to a live band cafe and enjoy the live music and hear friend’s voice together without any problem.
Now say "Hello" repeat with below spkr sound and try hear your voice and speaker sound together.
This speaker sounds like a real human voice and you should look for the speaker sounds like this. Alex/WTA
