to the regular occurrence of compression and rarification of air that we experience as sound.
Frequency Response
Is the range of frequencies that a speaker reproduces, lowest frequency to the highest. While the optimal normal is
Agood
H
A method of sound reproduction that emphasizes the highest possible adherence to the exact character of the original sound. This is a principal that must be paramount in every stage of the recording, transportation, and recreation of the signal to be fully operational. It is usually the listener’s equipment wherein this objective is most seriously compromised.
Hz (Hertz)
Cycles per second, named after Heinrich Hertz.
I
Impedance
The resistance to the flow of an electric current in a circuit. This is effectively the electrical load that a loudspeaker presents to the amplifier which drives it and is measured in ohms.

Input sensitivity
SPL (sound pressure level) a speaker produces, given one watt of power, measured from a
Interface

IP address
An IP (Internet Protocol) address is a unique computer address that enables electronic devices to communicate with and identify each other.
K
Kbps
Kilobits per second. A
kHz (kilo Hertz)
1000Hz or 1000 cycles per second.
