About the technology
The APL speaker correction solution is based on the concept that a speaker’s performance should be assessed not by the sound pressure it generates, but by the sound (acoustic) energy (power) it emits.
With this technology, we get excellent sound quality for each speaker, since each model sounds different, even if manufactured in the same way. Almost all speaker manufacturers use conveyor-type calibration, i.e. all models are calibrated according to one principle where a device is normally placed at one point opposite the speaker and calibration is performed automatically based on the measurement of the sound pressure generated by the speaker.
