I bought two of these 4x10 cabs for $75 for the pair. I've tried to look for the speaker brand and have had no luck. The closest I got was an old ad on Reverb for a Hohner amp with one of these speakers in it. (https://reverb.com/item/28469569-hohner-105-solid-state-guitar-amp). That Hohner amp does have that same, empty "If you write to us" sticker on the back, so it may be a set of Hohner 4x10 cabs. The grille cloth seems to match as well, but I cannot find any information on Hohner cabs online either. These speakers sound great and I was thinking about taking them out of one of the cabinets and building two smaller 2x10 cabinets with them, and then selling the large empty cabinet on CL. The cabinet itself is in good shape even though its made out of particleboard. The biggest downside is that the cabinet is sealed up and the back is not removable, but the front grilles do pop out, providing access to the screws that hold the speakers in place. I'm wondering if it makes sense to just flip them and look for some other speakers, but I'd really like to know what these are first. By the way, I just brought this one in from my shop storage room and that's mostly spider webs and only a few scuffs. Thanks in advance!
