Energy created by sound waves.
The physical science dealing with how sound is produced, propagated, manipulated and perceived. See also: Room Acoustics
An analog or digital device performing high-pass, low-pass and bandpass functions ahead of power amplifiers driving the transducers in a loudspeaker.
Advanced MOSFET OFR
A high-performance, amplifier power supply design that can efficiently provide the power needed by the amplifier, while running cool. Advanced MOSFET OFR power supplies are used in JBL mobile audio amplifiers to allow maximum headroom and drive difficult loads.
A device used to measure current flow in amperes.
The magnitude of an electrical current as expressed in amperes.
Unit of measurement for the electric current flowing through a circuit. Abbreviated: amp.
An increase in signal level.
The magnitude of an electrical signal (voltage, current or power), sound (sound pressure or intensity), or movement of a mechanical device such as a loudspeaker diaphragm.
An electrical signal in which the voltage (or current) waveform has the same form as the original acoustical sound waves. See also Digital
The electrically positive terminal of a battery, or the plate of a vacuum tube.
Apex Off-Axial Tweeter
Coaxial speaker design where the tweeter is located in the base of the woofer cone. Apex mounting equalizes signal path length differences of all frequencies handled by the speaker. This ensures all frequencies reach the listener's ear at the same time and improves stereo imaging.
A water based compound high in particulates which is used to adjust the mass of, and to add damping to, a variety of loudspeaker diaphragm materials.
To reduce the force or volume of a signal.
Audio Frequency Spectrum
The range of human hearing commonly accepted as 20 Hertz (cycles) to 20,000 Hertz (cycles).
An audio frequency signal in electronic form or after conversion to sound.
