Mid-range speaker

The most common material used for mid-range cones is paper, occasionally impregnated and/or surface-treated with polymers or resins in order to improve vibrational damping.

A mid-range driver is called upon to handle the most significant part of the audible sound spectrum, the region where the most fundamental frequencies are emitted by musical instruments, and, most importantly, the human voice, lie.

This region contains most sounds that are the most familiar to the human ear, and where discrepancies from faithful reproduction are most easily observed.

Since the ear is most sensitive to the middle frequencies produced by a mid-range the driver and amplifier can both be low power, while still delivering what is perceived to be good sound both in terms of volume and quality.

Nearly all crossovers are passive circuits, designed to match the characteristics of the drivers and their mounting, and are built of capacitors, inductors, and resistors.
