Grills on because I dont' want my 8 year old son to be curious about the drivers. I've never heard my speaks with the grills off.
Grills ON or Grills OFF?
With my Signature S2s, I prefer to listen with the grills on. Even though the highs are ever so slightly rolled off (which, with this speaker is not necessarily a bad thing), the dispersion and the ability of the speakers to disappear is better. Plus, I like the protection factor. How do you conduct your listening sessions, and why?
