The Edifier MR4 2.0 Studio Monitor Speakers provide reproduction without distortion. They have been professionally tuned for the flatter curve necessary to reproduce true music. With a 4-in. woofer and the support of its Class-D amplifier, the frequency can be lowered to 60 Hz for remarkable performance. A 1-in. silk diaphragm unit with a special coating ensures smooth and natural treble, and the specially designed integrated front panel combined with the cone bring clearer diffusion of the high frequency. Different from other entry-level monitoring speakers, MR4 adopts inductive and capacitive second-order frequency divider, so both the woofer and tweeter can acquire better signal input and reproduce the purity of the sound. 1/4-in. TRS balanced input jacks as well as unbalanced RCA inputs, an aux input, and a front headphone output allow the MR4 to be connected to different devices simultaneously. And with the special dual-mode sound effect, you can choose monitor mode to listen to a true audio you are creating for music production, or to switch to music mode for a daily music listening experience.
