I'll take that bet! Enough stuff like the SVT and Bassman Ten came with 32 ohm speakers that there are several replacement options: https://www.tubesandmore.com/products/speakers?filters=Ohms=32 Ohms Not that I've seen a lot of Bassman Tens, but all that I've seen had the 32 ohms speakers, or what was left of them. Fender used those in the PA columns as well. FWIW I'd say about half the Bassman Tens I've seen have one or more blown speakers, and, of course, if replaced, never with the correct impedance. The set of speakers in my parted together reissue tweed Bassman are Bassman Ten speakers that were blown, and sent out for recone at 8 ohms.
