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 102 ENERGY XL features 2x10" Markbass Neodymium custom speakers with 400W of power handling, and 1" driver with horn. The XL series bigger size per speaker allows to tune the cabinet in a different way, increasing the bottom-end response. Thanks to the material and technology used for the cabinet, although its larger size this 2x10" XL cabinet is still light weight and super portable (only 14.6 kg).
