The bass list probably has some advice. Being a DIY speaker builder, my experience is the refraction from the grill frame is the bigger culprit that the cloth itself. IE the speaker sounds the with grill frame with and without cloth. So I remove the grills when I listen for a slightly better sound. I would say if they are removable cover them in whatever (to gain domestic bliss) and then remove when listening. Now if I could only figure a way to hide cables! Any advice would be appreciated.

How important is the fabric on speakers to their sound? If I changed the covers of my speakers to a more decorative fabric to please my girlfriend, would that really be a big deal? Obviously, I wouldn't cover them with wool blankets, but would, for example, a light silk really sound that much different than whatever the manufacturers use? Given that many audiophiles think that the shape of their AC cords dramatically affect the sound, it is interesting that no one seems to discuss this topic. Any ideas or advice would be greatly appreciated.
