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

I guess MC is a pub?  I have to agree it's a lot more fun making a parody out of a pub.   

Harbeth speakers are designed to have the grilles so I'm not sure if saying removing the grille always improves the sound of a speaker.

OK....this makes me want to take them off my DQ10's tomorrow.  They sound fantastic but look hideous, but I could learn to live with it.

Interesting Subject! I helped design my Green Mountain Imago Speakers! I remember my designer sitting on the floor and switching capacitors while I listened! I got to choose what I liked! Then the tweaks began! First Marigo Green Dots on the mids and Dyna dome tweeters! Then the ribbons were Focal I think untouched! We added foam around the dome tweeters and that gave a more open sound!  The Crossovers are in external boxes with custom Kimber Cable! Plug In Modules were used to change Crossover Points! Everything we did made a difference! Now when it came to the grills! Definitely sounded better Without Them! They call me Goldenears! I use Tubes!😋

I generally prefer mine without grills, but don't often remove them.  It's easy to imagine that some recordings would sound better with the grills.  More detail is not always necessarily better.
