The MR4-powered Studio Monitor 2.0 speakers from Edifier feature professional calibration based on German Klippel system, a 1” silk dome tweeter and 4” diaphragm woofers that deliver pure sound. The dual-mode design lets you switch between monitor and music mode, and the MDF wood cabinets minimize acoustic resonance. They have front headphone output and Aux input, and a knob for power, volume and sound effects.
