As I was enjoying my OB7's with the servo sub in the OB H frame, I tried to imagine what these babies might sound like and tried to think of some kind of name.
What about Elemental? I think it captures essence of being bold, powerful, but natural.
Or what about a simple GR Research H.E. (series?) as in High Efficiency. Then you could consider the different models as number of components. So the coax, sub, and rear tweet could be called HE-3's, or no tweet HE-2's, etc... {I think high sensitivity is more proper than high efficiency, but I just like HE better than HS}

Oops... Now I see this had already been narrowed down
