This series 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 102 P XL features 2x10" Markbass classic ceramic speakers and a new piezo tweeter. The P series is created for those who like classic speakers but don’t want to carry heavy stuff. 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 16.7 kg), with amazing quality/price rate! 4 Ohm version.
