Speaker designers final voice their speakers with the grills on....therefore, the fabric will make a difference. Take a sample of original grill material to your fabric store and ask for a duplicate material with similar weave.
Speaker grill material, any real difference?
I need to replace the speaker grill material on a pair of Infinity Renaissance 90 speakers. After looking online there really is not much out there. It all seems to be the basic $15 a yard stuff. Is this what all the mfg's use? Or is there an "audiophile grade" material. I would hate to think I am spending only $30 when I could fork out the big bucks.
