ALTEC LANSING MODEL 416-8B LF 15" WOOFERS - CLEAN PAIR | eBay

This guy has 4, I dont recall ever seeing that style of label on a 416-8B. There is also no serial number, all my -8Bs have stamped serials.

I can see a date code there of 8726 I think so thats 1987, which is when a few of mine are from.

Are these fake labels?
