Loud Speakers and Amplifiers - Sound Engineering Term 2 - Lesson 1

front surface

There is usually little to control the dispersion of a tweeter other than the ________ of the cabinet in which tweeters are mounted.

objectionable phase

Where speakers can be redundant (i.e., more than one speaker can cover a frequency range), the anomalies in tweeter dispersion and frequency response can cause ________ cancellation and comb filtering when multiple devices are used together.

Horns

________ can also be used in multiples due to their controllability.

careful design

With ________, tweeters can sound very nice and pretty, but their behavior and polar pattern can be inconsistent.

audible frequency

A full- range loudspeaker drive unit is one that reproduces as much of the ________ spectrum as possible.

Sound

________ waves propagate in the shape of a sphere, spreading out horizontally and vertically.

single transducer

This is a(n) ________ that transforms electrical energy into acoustic energy.

input channel

One ________ is connected to both amplifier output channels.

RMS

________ stands for Root Mean Square, a mathematically defined statistical measure used by engineers to calculate the average of values over time.

drivers of speakers

The ________ are frequently measured in inches.

Bass Bins

________ are low frequency drivers with one, two, or four drivers of the same size.

tweeter

A(n) ________ radiates sound more or less directly into the air.

loudspeaker

A(n) ________ is a device that converts electrical energy into acoustical energy.

Loudspeakers and Power Amplifier

A two-way speaker has a low

and high-frequency driver, whereas a three-way speaker has a low-frequency driver (LFD), a mid-frequency driver (MFD), and a high-frequency driver (HFD)

A speakers peak power rating is the maximum wattage that its voice coil can handle in very short, occasional bursts

the power required to hit the speakers maximum output for a millisecond or two

While this peak rating may be a big, impressive number

like 1000, 1500, In the real world, 2000 watts isn't the most meaningful number
