Wilson Sophia 2: grills on or off ?


A question to Sophia 2 owners: how do you listen to your Sophias ?

With the grills on or off ?

With the grills on I found the a bit dark sounding.

I have WP 8's. I swear they are a little more open and focused with the grills off. My dealer doesn't think I could pass a double blind test on this...it's close, but there is that little bit more focus IMO...
Sharp edged baffles are best listened to with the grills on...there will be less edge diffraction. If you like it with grills off then add some quarter round wood so as to make smooth edges.
I had Sophia 1's and I listened to them both ways, and to be honest, to my ears there wasn' t much difference, at least in the nearfield. Since I was always paranoid about bumping into my speakers in my small room, I left the grills on. I think they look better this way anyway.
