7. Level issues

7.6 Unbalanced output mode

Output compression is sometimes applied in speaker processing for multi-amped speaker cabinets to protect drivers from overloading where other drivers in the same cabinet can still output more SPL. Also, full range output compression is sometimes applied to multi-cabinet speaker systems where parts of the system have spare SPL headroom. In both cases, the compression is used to make the system ‘louder’ - leaving out frequency ranges or locations above a certain threshold level. This could be seen as an audio quality problem - affecting a speaker system’s Performance. But because it is applied as an intended process - with the goal to make the system louder at the cost of losing the designed SPL balance between loudspeakers at high volumes, it affects the Response (sound quality) - and not the Performance (audio quality).
