Avalon speakers are designed to be played with its grilles ON at all times, I have seen/heard some Avalons where grilles are not placed and many of its sonic attributes disappear at the sake of a more "transparent" sound.
I am not sure if there is other speaker that needs to be "dressed" as a fundamental part of its design.
