Thanks for the compliment Dusty. I played heck finding a suitable covering for my speaker doors until an audio guy mentioned the Ponte cloth. It's super stretchy and glues well with 3M fastbond 90 on to MDF.
On a side note, those 3 speaker covers are actually doors and behind them, on full extension pullouts, are speakers that weigh 190 pounfd EACH! (the side ones) LOL They shoot forward and to the sides so they had to be on pullouts for the "full affect". The center speaker is on a pullout too as it shoots forward and up! LOL
