Technics Speakers Model SB 5000A questionregarding insulation


I just purchased these speakers...opened them up tp see how they were made.  Decent built quality.
My question is Insulation is gray / Blue in color.
Could this be asbestos ?
Opinions please.
thanks

If it is, try and avoid spending the next 20 years with your head inside there.
