Central Speakers Central Speakers play a big role in home theatre systems. They always produce the dialogue in movies and big explosion effects typically start from the central channel continuing outward. The only problem with Central Speakers today is that they are not being taken seriously. Central speakers today lack the crisp, high, frequencies that are necessary, even in dialogue. To add to the problem, Dolby Surround decoders have crossovers and amps for the central channel that restrict it to produce frequencies around 1,000 Hz. When choosing a Central speaker, strive for a broader range of frequencies, perhaps all the way to 30 kHz All central speakers should be placed directly on top of the TV or viewing screen. If you have a TV, be sure that the speakers are magnetically shielded to prevent distortions on your screen.
