They are designed to provide excellent sound quality and feature two playback modes - Monitor and Music. The convenient knob allows easy access to the functions, and multiple available connections such as TRS, AUX, or RCA enable you to connect various devices.

With a Class-D amplifier and a 4-inch woofer, the frequency can be lowered to 60 Hz, and the use of DSP provides an even more interesting sound. The MR4 also features an advanced crossover for better input signal and clearer sound. The speakers are designed to deliver great sound.
