She loves me she loves me not!

Sonically, I have always found speakers to be more open sounding with the speaker grills off.  If you're concerned about protecting the drivers you can always put the grills back on after a listening session.

+1 @ naked.

They are a beautiful set.

I hear more upper scale frequencies without grills on Elac DBR62 ... others no discernable difference.  Obvious design differences at play.

@motown-l I guess it’s true that perception is everything. I also have Revels and prefer the sound with the magnetic grills installed. I had Focal’s previously and preferred them without their grills. Go figure. 

I took my grills off and put one in each corner to use as a bass trap. I only put them back on when I have guests or my exterminator over who have probing fingers and like to touch things.
