Abstract: An ultra-low distortion loudspeaker is described. The ultra-low distortion, on the order of 0.1% THD (total harmonic distortion) or less, is achieved by novel means. The signal from a typical preamplifier, i.e., line level signal, is fed into an ultra-low distortion, high order band-pass filter, the band-pass filter splitting the component frequencies into various bands. Secondly, the output of each band, or group of bands, is then input to an ultra-low distortion power amplifier, each driving an individual acoustic transducer. The band-pass filters, power amplifiers, and acoustic transducers, along with a suitable enclosure(s), comprise an ultra-low distortion integrated loudspeaker system.
