Think of a grille as a bra. If there aren't children about, then the tweeters/woofers should be in clear view IMO. Now if he could only convince his caregiver of this notion. I'll second that!

HEHE, Scott and David. Maybe I can sometimes, but it's older balding guys that make them think otherwise.   BTW, Scott sat beside me at dinner on Friday night on the weekend of the reunion........just sayin'! 
The only reasonable argument for owning a gun is to protect yourself from the police.

I used to have the grills off for about 8 months as I like the look of the speakers naked But about a months ago, my little one started crawling so I had to put the grills back on. Well I don't know if it is a placebo effect but I have the impression that they sounded better before. The grills are supposed to be acoustically transparent so it could just be me, however, it would be interesting to take measurements with the grills on and off.

It's a placebo effect. The grilles are acoustically transparent with inaudible differences in our double-blind tests at the Axiom plant.
Psych-acoustic bias has a huge effect.

Typo there, it should be "psycho-acoustic" bias.
And I should qualify my statement: differences between grille-on and grille-off are inaudible in blind tests using musical program material. You might be able to hear a slight difference using a full bandwidth pink-noise test signal, which is extremely critical and contains equal energy per octave across the musical spectrum. It's been some years since I've tried that.

Some speaker tests(none involving Axioms)have shown response curves with and without grills. Generally, there's been a slight(about a dB or two)loss in the top octave with the grills, but it's highly doubtful that this would be audible in a blind listening test such as Alan described. Of course, the subjective review part of those tests often included a claim such as a loss of "air" with them on.

Speaking of Placebo affects, I SWEAR the picture on my TV is brighter, has more contrast and less colour banding since I added a Sub to my Home Theatre.
I *know* its just in my head, but seriously... it *does* look better! (To me anyway)
