I would bet the VHT speakers are made for them by some major speaker company. Probably Emi or Celestion, not that it really matters other than satisfying my curiosity. I haven't heard the 10" but those chromeback 12s are good speakers from what experience I've had with them so I'm sure the 10s are good too. I'd like to pick one up myself, it would be good for my Sp6 head and being 50w I could use it with my Pignose 40! The little Pignose 40w tube amps are great, I modded mine more like a jtm45/5f6a bassman.
