This is a further example of how Markbass is always one step ahead in innovating using state-of-the-art technologies. 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. The MB58R 151 PURE features 1x15" Markbass Neodymium custom speaker. Ultralight and portable (only 14.9 kg), it offers deep and warm sound in conjunction with great clarity and definition from the new hi-fi tweeter. With its 400 W of power handling it can be used as a standalone or matched with MB58R 102 PURE or a MB58R 104 PURE for a super versatile and powerful stack!
