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.

Not to miller the thread, but what type of adhesive do you recommend to attach the cloth to grill frame? Im thinking of re-doing mine (manuf. says $400. for new ) but unsure of best adhesive. The frames are metal.
@Wino- A thin bead, from a hot-melt glue gun. Work fast, as the glue cools quickly. Trim excess material with an X-ACTO #1. Done correctly; it's a whole lot neater than any other method.
Hi all ! I took the grilles from my Thiels to a car audio shop . They recovered them with the same looking stuff that was original . Think I paid $20 for both .
