The use of an equalizer can be a handy way to help improve sound quality and correct obvious performance issues with quality sound systems. Although an equalizer’s various filters can be used effectively to expand or decrease the “balloon” found at a specified octave band, its main weakness is that it’s an indiscriminate tool that boosts energy for all outputs throughout the system. Sometimes, a more discriminating approach is needed to reshape the radiation balloon correctly for maximum audio system performance, which can open a whole new world of possibilities beyond those possible with regular use of an equalizer.
Key Takeaways:
- In order to address a flat-on axis, it is important to consider both the on-axis and the off-axis during the editing process.
- In order to produce the best equalization results, try to locate the best common denominator within the various axis forms.
- Loudspeaker interactions are good characteristics to implement, but they do have a tendency to cause huge swings.
“The procedure often followed for equalizing a loudspeaker is to place the measurement microphone on-axis and adjust for the flattest frequency response. This involves cutting and boosting some filters on the equalizer.”
