Correct! They're from Phoenix, and they were distributed by Randall. You'd know better than me about the drivers, though! That's awesome that you got to go to the factory like that! The 610 cab is stand alone, btw.

I bought the VTB-120 head (now pushing closer to 180w), but I'm using Bill Fitzmaurice cabs.
I think $300 is a damn fine deal for this cab after hearing it, though. It's still in good condition.
