Need raw specs if possible. Basically impedance and true power handling. Who makes them would be nice to know but not as important. They would have to be 4 or 16 ohm drivers, hopefully 16 for what I might try with this cab in the future. With the grille off they look beefier than 50w drivers, but I have not seen the backs of them yet and don't plan to take the cab apart till I know if it is worth it or needed. True specifications, not educated guess speculations please. Jimmy? Anyone? Thanks!
