What are some of the advantages of using grilles versus not using grilles? So that's an interesting question, because when we consider why do we actually have the grilles in the first place, it's mainly to protect the drivers or to change the visual appearance of the loudspeaker. In terms of sound, it's quite simple. All of our loudspeakers are tuned to sound best without the grilles. Anything in front of the drivers will affect the sound. And in terms of sound performance, we don't want that. So normally we tune them without the grille. We have a grille that you can put on either to protect or to change the appearance. But it will sound a little bit worse when you put on the grille. What affects the sound coming out of the speaker when you put on the grille is both the cloth itself, but it's also actually the frame that the cloth sits on. Because the sound that goes from the drivers of the speakers will actually travel across the front of the speakers, around the speakers. And when that hits the frame, it will actually diffract the sound going into the room; it'll create some sort of distortion effects just from the frame itself. So even if you had no cloth, it would actually still affect the sound. So no matter how good the cloth is, the frame itself will still impact the sound a little bit. So all else being equal, it will sound better without the grille. So there are different types of cloth, different qualities of cloth, and in this case, this is all about how open is it, how acoustically transparent is it? And all of the cloth that we use on a Dynaudio speaker is, of course, very acoustically transparent in all of our models. So that's a big consideration in designing the speakers. One of the speakers where we went to extremes in that regard is on the active Focus speakers. And so what we did on the Focus is we built in a small sensor so that when you put on the grille – put that on the speaker – the speaker will actually sense that now the grille is on. And then we created an EQ to kind of compensate for the grille in front of the drivers to make it sound much more similar to when you don't have the grille on. And that happens automatically as soon as you put the grille on. So we were very careful with how we designed the grilles and built that into the design of the speakers, to make as little impact as possible. But if you want the perfect sound, take off the grille.
