The combination of speaker and amplifier

In the past Commercial Audio system, same speaker was installed for emergency and announcement so the output range of amplifier was installed according to the output range of speaker. However, present Commercial Audio system was utilized for not only broadcasting but also for BGM. Therefore, the higher output of amplifier and speakers are needed for clear announcement and more dedicated music sound. The output of amplifier should be installed twice bigger than output of speaker for high quality and clear sound.
