- Loudspeaker technology
Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current).
See Powered speakers and Amplifier
Audio crossover
Audio crossovers are a type of electronic filter circuitry that splits an audio signal into two or more frequency ranges, so that the signals can be sent to loudspeaker drivers that are designed to operate within different frequency ranges. Powered speakers and audio crossover are loudspeaker technology.
See Powered speakers and Audio crossover
Audio signal
An audio signal is a representation of sound, typically using either a changing level of electrical voltage for analog signals, or a series of binary numbers for digital signals. Powered speakers and audio signal are audio engineering.
See Powered speakers and Audio signal
Bass amplifier
A bass amplifier (also abbreviated to bass amp) is a musical instrument electronic device that uses electrical power to make lower-pitched instruments such as the bass guitar or double bass loud enough to be heard by the performers and audience. Powered speakers and bass amplifier are loudspeakers.
See Powered speakers and Bass amplifier
Class-D amplifier
A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches, and not as linear gain devices as in other amplifiers.
See Powered speakers and Class-D amplifier
Clipping (audio)
Clipping is a form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability. Powered speakers and Clipping (audio) are audio engineering.
See Powered speakers and Clipping (audio)
Compression driver
A compression driver is a small specialized diaphragm loudspeaker which generates the sound in a horn loudspeaker. Powered speakers and compression driver are loudspeaker technology.
See Powered speakers and Compression driver
Computer speakers
Computer speakers, or multimedia speakers, are speakers sold for use with computers, although usually capable of other audio uses, e.g. for an MP3 player. Powered speakers and computer speakers are loudspeakers.
See Powered speakers and Computer speakers
Disc jockey
A disc jockey, more commonly abbreviated as DJ, is a person who plays recorded music for an audience.
See Powered speakers and Disc jockey
Dynamic range
Dynamic range (abbreviated DR, DNR, or DYR) is the ratio between the largest and smallest values that a certain quantity can assume.
See Powered speakers and Dynamic range
Dynamic range compression
Dynamic range compression (DRC) or simply compression is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or compressing an audio signal's dynamic range. Powered speakers and dynamic range compression are audio engineering.
See Powered speakers and Dynamic range compression
Electromotive force
In electromagnetism and electronics, electromotive force (also electromotance, abbreviated emf, denoted \mathcal) is an energy transfer to an electric circuit per unit of electric charge, measured in volts.
See Powered speakers and Electromotive force
High fidelity
High fidelity (often shortened to Hi-Fi or HiFi) is the high-quality reproduction of sound. Powered speakers and high fidelity are audio engineering and consumer electronics.
See Powered speakers and High fidelity
High-end audio
High-end audio is a class of consumer home audio equipment marketed to audiophiles on the basis of high price or quality, and esoteric or novel sound reproduction technologies. Powered speakers and high-end audio are consumer electronics.
See Powered speakers and High-end audio
Home audio
Home audio refer to audio consumer electronics designed for home entertainment, such as integrated systems like shelf stereos, as well as individual components like loudspeakers and surround sound receivers. Powered speakers and home audio are consumer electronics.
See Powered speakers and Home audio
Home cinema
A home cinema, also called a home theater or theater room, is a home entertainment audio-visual system that seeks to reproduce a movie theater experience and mood using consumer electronics-grade video and audio equipment and is set up in a room or backyard of a private home.

Negative feedback
Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
See Powered speakers and Negative feedback
Paramount Pictures
