cerasonar 4050 reference

All models of the cerasonar reference series feature the new cerasonar XT6000 high-performance exciter,
which is capable of a considerably higher sound pressure level. With the cerasonar MCC system (mode
correction control), a more even frequency response is achieved, which has a noticeable effect on the tonal
balance as well. The reference series is particularly suitable for pure stereo and surround installations. The
reference models offer high-class sound at party volume levels.
