Once again Marco De Virgiliis with his pioneering soul has managed to create this new series of products which has really nailed the tone and power versus portability issue. This is a further example of how Markbass is always one step ahead in innovating using state-of-the-art technologies. The MB58R 121 ENERGY features 1x12" Markbass Neodymium custom speakers and 1" driver with horn. With its 400 W of power handling it can be used as a standalone with a Markbass head or as extension cabinet for the Mini CMD 121 and CMD 121 combos, it’s a very portable solution (weights 11.6 kg) that covers all of your needs and also ideal for double bass and acoustic bass as the sound of acoustic instruments is faithfully reproduced by this amazing cabinet.
