Korg B1

The built-in speaker system is equipped with MFB technology. This active servo system controls the movement of the cone, allowing low frequencies to be reproduced with minimal distortion. In use, the movement (velocity) of the speaker cone (vibrational surface) is detected, and a signal that compensates for the mechanical response of the speaker and speaker chamber is returned to the amp (feedback). This Motional Feedback technology allows the system to achieve ideal frequency response, and permits the low-frequency range to be reproduced accurately; any coloration of the sound caused by the speaker enclosure is immediately corrected. This well-regarded technique reinforces the low-end response—particularly with small speakers—and can also help to compensate for the room acoustics.
