some speakers, like Avalon, are designed to listen with grills on, others it's up to you...I always put grills back on at end of day...(except for my Avalons...)..
She loves me she loves me not!
So - as in the saying above when de-pedaling a daisy...
Speaker grills on speaker grills off.
The reasoning for my question if I keep them off inevitably I will damage them moving them around when in the garage- -forget where I put them - and bitch cause they take up space.
Thank you for the education.
