Bogner Helios 2x12 Insulated Backboard

[Frehley12]

I picked up a used Bogner Helios 2x12 cab. I noticed the backboard has white "insulation." Is that standard?

Yes.
All the Bogner cabs have it.

Cool. The quality of this cab inside and out is beautiful. The mix of V30 and Creamback 65 speakers is a versatile combination. Killer cab. I'm liking it more than my EVH 4X12 and JCM 800 4X12 with original G12-65s.
