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?

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.
IMO it depends on the speakers first; and to lesser mesurable effect, the gear driivng them.

I used to have Totem Forests and Arros (even bi-amped) .... taking the speaker grilles off was strongly preferred.

Now with a new premium integrated amp and cdp (REGA Osiris and Rega ISIS valve) married up to my new REGA R9 speakers, leaving the speaker grills on has no effect and you get the dust et al protection to boot.
Without; I could see how attenuating the high might be a benefit in some cases but I can't see how the grills could improve imaging. As to disappearing; well , with the grills you can't see the drivers so I guess you could say they "disappeared".
