I a m using an old marshall 212 cab with the rm 100. The speackers were replaced before i took posesion. Its loaded with kendrick blackframes. I have rewired the speaker in series hoping to get 16 ohms. Opened it up used the multimeter and found each speaker at 6.2 ohms the wired in series 12.4 ohms. does anyone know if its safe to hook this to the rm100 switched for 16 ohms? and also paired with a 16 ohm 412[/list]
