John, Any factory stuffing data for the 2ax's? Thanks! PM

It's the pattern that intrigues me... the darkening only occurs over the cut-outs, indicating the cause of the fabric darkening comes from BEHIND the grill covers, not in front of it (sunlight, smoke, fried foods).

Just a thought... Having just recently jumped back into vintage AR (after a 30+ year absence), I've noticed a couple of thing: some AR speakers have pots shot to hell, others simply need a cleaning; AND some grills look fine, while others are badly stained (darkened) over the cut-outs. In my LIMITED experience there is a correlating factor: rock wool. The ARs with fiberglass stuffing have pots in better condition (as has been discussed), and the grills don't have as much (or any) darkening of the cloth over the grill cutouts. Isolated, or is the sulfur leeching out of the rock wool also darkening the cloth?
