The 1960AV base speaker cab is switchable between Mono (4 or 16 Ohms) and Stereo (8 Ohms per side). The two Mono impedance options provide extra amp-matching capabilities while the stereo capability makes it ideal for rack systems. The G12 "Vintage" 70W speakers give this cabinet an extra warm sound.
