This setup is for employing the Hundred Duo Twelve as a head; its speaker is nonfunctional in this configura-
tion. Unplug the internal speaker from the Speaker 1 output jack. Using heavy-gauge speaker cords, connect
the output jacks labeled Speaker 1 and Speaker 2 to the speaker inputs on extension cabinets with an 8-ohm
impedance and power-handling capacity of 100 watts. You can also hook up two 16-ohm cabinets or two 4-
ohm cabinets, but never use two 2-ohm cabinets, because the overall impedance load will be too low for the
amplifier and could result in damage.
