Loudspeaker Systems Flashcards
1
Q
Loudspeaker
A
a transducer that converts electrical energy into acoustical energy
2
Q
Crossover
A
used to separate the audio signal into different frequency groupings and route the appropriate material to the loudspeaker or amplifier in order to ensure that the individual loudspeaker components receive program signals that are within their optimal frequency range.
3
Q
Passive Crossover
A
One that does not require power
4
Q
Active Crossover
A
Requires power
5
Q
different drivers and frequency ranges (5)
A
Tweeter- High Horns - Mid to High Cone - Mid Woofer - Low Subwoofer - Lower
6
Q
Loudspeaker Sensitivity (2)
A
- defines how efficiently a loudspeaker transduces, or converts, electrical energy into acoustic energy
- a more sensitive loudspeaker would provide a higher acoustical energy output than a less sensitive loudspeaker
7
Q
Loudspeaker Impedance
A
- loudspeakers have a nominal impedance rating
- Most are rated at four, eight, or sixteen ohms. Some are rated at six ohms
- impedance is frequency dependent, the impedance will not be the same over the loudspeaker’s entire frequency range
8
Q
Knowing a loudspeaker’s impedance (3)
A
- help you find the total impedance load when you connect multiple loudspeakers to the output of a power amplifier
- will help you to avoid wasting power, overloading your power amplifier, and damaging your loudspeakers
- give you optimum volume by reducing distortion and noise, and avoiding uneven sound distribution
9
Q
Loudspeaker Components
A
a driver within an enclosure
