Understanding Speaker Systems
Sound Production Basics
Speaker systems are designed to produce sound by converting electrical signals into sound waves that can be heard by humans. The process of sound production starts with the electrical signal that is sent from the audio source to the speaker. The signal is then converted into mechanical energy that causes the speaker cone to vibrate. As the cone vibrates, it pushes and pulls the air molecules around it, creating sound waves that travel through the air to the listener’s ears.
Speaker Components
A speaker system consists of several components that work together to produce sound. The main components of a speaker system include the driver, the crossover, and the enclosure.
Driver
The driver is the part of the speaker that actually produces sound. It consists of a magnet, a voice coil, and a cone or dome. When an electrical signal is sent to the driver, the voice coil moves back and forth, causing the cone or dome to vibrate and produce sound waves.
Crossover
The crossover is a circuit that divides the audio signal into different frequency ranges and sends each range to the appropriate driver. This ensures that each driver is only producing the frequencies that it is designed to handle, resulting in a more accurate and balanced sound.
Enclosure
The enclosure is the housing that holds the driver and crossover components. It is designed to enhance the performance of the speaker by controlling the movement of air around the driver and reducing unwanted vibrations and resonances.
In summary, understanding the basics of sound production and the components of a speaker system is essential for choosing between active and passive speakers. It is important to consider factors such as the intended use, available space, and budget when making a decision.
Defining Active Speakers
Active speakers are a type of speaker that comes with built-in amplification, meaning they don’t require an external amplifier to produce sound. They are also known as powered speakers and are self-contained audio systems that can receive an audio signal and amplify it to produce sound.

Defining Passive Speakers
Passive speakers are a type of speaker that requires an external amplifier to produce sound. They are called passive because they do not have a built-in amplifier like active speakers do. Instead, they rely on an external amplifier to power the speakers and produce sound.
External Amplification
Passive speakers require an external amplifier to produce sound. The amplifier is responsible for providing the power needed to drive the speakers and produce sound. The amplifier is connected to the speakers using speaker wire. The amplifier receives an audio signal from a source, such as a CD player or a computer, and amplifies the signal before sending it to the speakers.
Speaker Wire Requirements
Passive speakers require speaker wire to connect to an amplifier. The speaker wire is used to transmit the audio signal from the amplifier to the speakers. The speaker wire must be of sufficient gauge to handle the power output of the amplifier. The recommended gauge for speaker wire depends on the distance between the amplifier and the speakers, as well as the power output of the amplifier.
In summary, passive speakers require an external amplifier to produce sound, and they are connected to the amplifier using speaker wire. The gauge of the speaker wire must be appropriate for the distance between the amplifier and the speakers and the power output of the amplifier.
