Even with the same impulse input for each channel, the response waveform will be distorted without proper settings and speaker drive

control. By aligning the speakers through accurate speaker distance measurement, and matching the timing across the frequency range with

Full Band Phase Control, an ideal reproduction environment is created where the timing for all channels for the full bandwidth is matched.
