The Markbass MB58R MINI CMD 121 PURE bass combo features a 1x12" neodymium custom speaker and a hi-fi tweeter. This combo delivers 300 watts (RMS) of power standalone, and it can be easily upgraded to a powerful 2x12" 500W rig with the addition of a MB58R 121 PURE cabinet. The sound that comes from this amp simply does not match what you see when you look at such a small and ultralight cube, weighing only 21.7 lb.
