The MB58R series is a further example of how Markbass is always one step ahead in innovating using state-of-the-art technologies. The MB58R 102 ENERGY features 2x10" Markbass Neodymium custom speakers and 1" driver with horn, and it weighs only 11.1 kg thanks to the revolutionary enclosure material. This cabinet works great on its own, plus makes up an amazing stack when added to another Markbass 8 ohm cab (for example, another MB58R 102 ENERGY or a MB58R 151 ENERGY). 4 Ohm version.
