All four of my 128H had the same texture on the back as the two PR300s.
That's a shame about your stuff at Edgewound's. As I've mentioned before, he is pretty active on the "JBL Vintage speakers" Facebook group, to the extent that he took time to argue with me about the pair of 044s in my L150A within the last week or so. Never met the man and appreciate his expertise as experienced by those I trust here, but he is a bit stubborn and condescending in his replies. I will give him cred for being involved, but that may be time he should have spent getting his jobs done.

Umm, don't know how that's possible. All four of my 128H have white Aquaplas cones. The H-1 in my 4412A are black.
