Products and Technology
This guide has been created to help in the specification and installation of Genelec Residential and
Home Theater Speaker Systems. Many questions arise from customers' perspective and installers'
experience and it is hoped that this guide will give a better sense of direction and an improved Genelec
Home Theater experience.
1.1
Some Genelec History
Genelec has a world-wide reputation of designing and manufacturing the finest active monitors for the
professional audio market. Since its founding in 1978, Genelec has supplied the most discriminating
broadcast and recording organizations around the world with active audio monitors capable of meeting
their highest requirements. Meeting those expectations has not been easy. The tremendous amount
of research and development activity that is the key of Genelec's success in professional audio also
benefits the Residential and Home Theater products. The goal remains the same – to design a tightly
integrated audio system to provide an accurate and reliable service.

Active Loudspeaker Technology
The concept of an active loudspeaker is simple;
•
Remove the passive crossover components from the traditional loudspeaker design,
which are placed after the single amplifier on each channel.
•
Design a custom electronic crossover, which is placed before the integrated amplifiers.
•
Use as many amplifiers as there are drivers.
See Figure 1 for a block diagram of passive vs. active design. Active design ensures that each driver
(woofer, midrange and tweeter) has its own band-passed amplifier to which it is directly coupled and
matched. This concept greatly reduces distortion, improves dynamic headroom and frequency linearity
and increases the system total sound pressure level.
