The 1960B 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. It also features the legendary strength and durability that is standard to all Marshall cabinets, as well as the heavy-duty castors to help you shift it on stage.
