The internal glue job screams mass production.
The tweeter screams NOT white van.
I am thinking newer boutique where these were mid/woofer, tweeter and there was a bass unit.
Lack of ID, badge, logo screams small startup company, maybe flash in the pan.
Screams, good parts, decent show off cab, high profit margin to cover low production.
I do some Google research on weird stuff that comes through and see crazy expensive boutique stuff that is probably more show than go.
Look at brands that places like Definitive Audio in Seattle sells.
