Recently I removed the grill from my LSI-9s on the front,just for kicks,and surprisingly I found it,that it sounds "cleaner and more transparent".I say surprised because I figured that it was designed for grill on. I know that this is my subjective opinion,and that the "next guy" could very much prefer these speakers with the grill on,which is why I started this thread. Have you guys tried this yourselves, what's your opinion on the outcome?Would you share? Thanks. PS: please no theoretical discussion as why it does/don't/should/shouldn't impact the sound,as this is a sharing experiences thread,feel free to start a technical discussion thread if one needed. Thanks!
