grills or no grills on your speakers..matters?

I keep the tops off and the bottoms on now while listening. Wilson Witt series II. The Lipinski L707's were always run with the grills off. They don't even cover the tweeters on their speakers. I run an Orick Air Purifier to keep the dust down in the listening room.

Wolf-Garcia, I believe my Preludes do better than any other speakers I've owned with grills on.

Most Subs with grills off will make your system come alive.

I really don't need the grills on my Preludes as they do have screens on the tweeters...I dust the woofers from time to time as tiny dust particles do not deserve to ride around on my drivers. I put new grill cloth on my sub as it had been damaged by the previous owner, and I can't imagine it blocking anything under its 50 hz or so frequency range...so it stays.

I'll add that when my grills are off and people come to visit, they're drawn to the speakers like a magnet (no pun intended). With grills on, they sit down or head to the kitchen because they known where I keep the scotch.
