grilles on or off the speakers??


As most of you are aware, there are a number of speaker manufacturers that claim a "specially designed" grille for their speakers, that prevent edge diffraction and whatever and do no recommend they be removed.

Since no women were inviting me to the Caribbean, and having nothing better to do, I decided what the heck and put the grilles back on my speakers. I anticipated no effect, but they sounded different. They went on and off several times, and there is clearly an auditory diffence...not necessarily better or worse either way...just different

SO, what do you think, grilles on or off, and are specially designed grilles snake oil or science??

Thanks

Not sure why a thread usually ends up with someone being condescending and mean spirited. Of course I, and most anyone interested in audio, set our systems up to our liking and our listening taste and our satisfaction That doesn't mean discussion is a bad thing and we are all neurotics and stupid.
I was interested in the opinions of many of the knowledgable people on this site, as to whether or not they think a speaker can actually (you know... scientifically, using physics) tune a speaker with its grille to improve its fidelity. Of course it sounds different with the grille..my stereo also sounds different when I hear it through a door or wall.
And finally, learning through magazines and online forums is a good thing...reading is good.
To LoomisJohnson,

Yes, there are Totems and Revels that don't include the grilles, and others like Paradigm with their "specially designed grilles" and don't recommend using their speakers without them. That is why I was interested in the group's feeling on grilles, and their experiences.

Thanks for your input
Are Stereophile speaker measurements done with grills on or off? Do they say?
