OMG, just removed my speaker grills and the sound just opened up to a new level!

OK, try this. Take the grills off and listen for a while. Then place one grill in front of your head while listening. If you don’t hear a difference in the sound it’s because the reason is not physical. Fair enough?

My Acoustat electrostatics went nude 15 years ago.  It was one less cloud on the window.

Quad ‘75s are a little different. Now, those heavy metal grills ARE physical. Whose brilliant idea was that? 

Hello, what planet are you from? You mean you didn’t know removing the grill off ANY speaker improves it’s transparency and openness? These are the basics, what level in this hobby are you at?  Sorry if this sounds a little rude, no offend but I can not believe that you are actually surprised with this basic knowledge. 

lowtubes, chill, no reason to ride the OP. Everyone is at a different place. Some people are more into the media collecting, etc. and don't pay that much attention to the nuances of gear, etc. 

As for speakers that are "voiced" with grills on, whatever. It's usually because it looks like crap, for they used ugly materials underneath to save money - not always the worst thing cost-wise - but a disadvantage when it comes to performance. Yes, this is true of Vandersteen and Magnepan, too. Sorry, fanboys.  :) 

Do I care if the manufacturer says the speaker is better with a grill? No. I'll probably never own it. It's that important when you put systems together for high performance. I get the aesthetics thing and WAF etc, but I'll not quickly succumb to acceptance of a speaker without removable grill. In 30+ years a speaker with a grill has never performed superior to without.  The only exception, as I said, was if they did a poor job on the tweeter. YMMV
