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 series is a further example of how Markbass is always one step ahead in innovating using state-of-the-art technologies. The MB58R 102 PURE features 4x10" Markbass Neodymium custom speakers and a new hi-fi tweeter very focused in high range with excellent transient attack; it weighs only 16.1 kg, with 800 W (RMS) of power handling! 4 Ohm version.
