It also allows the manufacturer to implement elaborated circuitry that protects the system from misuse
therefore increases reliability:
-
Input Protection ensures that no signals above the acceptable input range enter and damage the
active electronics.
-
Driver Protection allows for the maximum power output from the system while ensuring that the
drivers cannot be damaged by over driving the system.
-
Thermal Protection shuts down the amplifiers if the acceptable operating temperature for the
electronics is exceeded. When the temperature drops sufficiently the system resets itself.
The Genelec active loudspeakers also feature proprietary Room Response Controls (see Section 4)
which help optimise the loudspeaker's tonal characteristics once they are installed in a home theater.
Note that the amplifier can be located away from the enclosure but the loudspeaker/amplifier system is
still an active system because everything is designed to work together.

Directivity Control Waveguide
In 1983 Genelec designed a loudspeaker system that was radically unique in shape and acoustical
properties. The entirely smooth and curved enclosure provided no sound coloration of the drivers and
excellent control of the sound dispersion into the room. This was the birth of the revolutionary Directivity
Control Waveguide™ (DCW™) technology. Today the DCW™ is a waveguide in which is mounted the
high frequency (in three-way loudspeakers, midrange and high frequency) driver that controls the angle
of dispersion.
The aim of the DCW™ is to match the frequency response and directivity of the drivers in the loud-
speaker leading to a great improvement on the performance of a direct radiating multi-way loudspeaker.
The result is an excellent match of the overall frequency response on and off axis. This control of the
directivity reduces incoming reflected sound at the listening position, thereby minimizing room coloration
and improving the entire sound stage imaging. The DCW™ technology allows for extremely high audio
consistency between very different Home Theater installations.
The DCW™ technology also improves the drive unit sensitivity even up to +6 dB, and therefore increases
the maximum sound pressure level as well as decreases the drivers' distortion.
