State of the art and technology with an amazing power to weight ratio.The MB58R MINI CMD 121P features 1x12" classic ceramic speaker but thanks to the revolutionary enclosure material and technoly we used for the MB58R series this combo weighs only 23.1 lbs / 10.5 kg, it’s 300W @4ohm / 150W@8ohm power and a great choice for those who like classic speakers but don’t want to carry heavy stuff.
