I, too, have Dunlavy V's and they sound more transparent with grills of,(measures flater too, +/-2 db)eventhough the manual says they are designed to be listened with grills on.
How grills affect?
I've purchased grills for my Totem Forest speakers to keep my little boy's hands away from the drivers. Somehow I've realized that the grills didn't degrade the sound but even otherwise. How did that happen? Please share your experiences.
