Abstract: An amplification system which includes a source of electrical audio signals, a first amplifier, a second amplifier, a plurality of loudspeakers, and a first phase of the first amplifier and a second phase of the second amplifier reproduced in parallel having a time delay between first and second phase amplification for out of phase correction. The time delay is configured to correct poor sound signals while amplifying weaker harmonics and sound signals of different frequencies, thereby adjusting sound output of the amplification system and acoustical characteristics of a room. The amplification system is useful for providing improved sound quality and increased audio efficiencies.
