Constant directivity implies an equal frequency response independent of listening angle.

A bass reflex system (also known as a ported, vented box or reflex port) is a type of loudspeaker enclosure that uses the sound from the rear side of the diaphragm to increase

Frequency response is a measure of a system's output in dB versus the output in Hz for a given stimulus. In case of a loudspeaker, the sound pressure is measured as a function

Frequency is the number of occurrences of a repeating event per unit time. The SI unit of frequency is the hertz (Hz), named after the German physicist Heinrich Hertz; one hertz means that

Digital signal processing (DSP) is the numerical manipulation of signals, usually with the intention to measure, filter, produce or compress continuous analog signals. It is characterized by the use of digital signals to
