What is the actual setting of a Filter/Crossover referred to as?

The actual setting of a filter or crossover in audio production is often referred to as the Knee Frequency or Crossover Point. This terminology describes the specific frequency at which audio signals begin to be attenuated or directed through the filtering process.

In the case of a crossover, which separates different frequency bands for different speakers (like subwoofers, mid-range drivers, and tweeters), the crossover point is crucial for ensuring that each speaker operates within its optimal frequency range. The term "knee frequency" is also applicable because it represents the point at which the transition occurs, indicating the beginning of the filter's influence on the audio signal.

Thus, the combined term captures both concepts, highlighting the importance of understanding the specific frequency settings used in audio filters and crossovers to achieve clear and balanced sound quality. This integrated terminology reflects the practical application of both technical definitions within the context of audio design and production.
