Basic Terminologies
Before we dive into the details of multi-channel home theater systems, let’s review some basic terms that you will encounter in this topic.
-
Stereo sound
This is the most common type of audio that uses two channels (left and right) to deliver sound. Stereo sound can create a sense of depth and width in the soundstage, but it cannot create a surround effect. Stereo sound is suitable for both music and movies, but it may not be as immersive as multi-channel sound.
-
Surround sound
This is a type of audio that uses multiple channels (usually more than two) to deliver sound from different directions. Surround sound can create a sense of realism and involvement in the soundstage, as it can make you feel like you are surrounded by the sound. Surround sound is ideal for movies and games, as it can enhance the atmosphere and the action.
-
Stereo system
This is a speaker system that consists of two speakers (left and right) that are designed to reproduce stereo sound. A stereo system can be enhanced by adding a subwoofer (or an LFE channel) to improve the bass response. A stereo system can be active (with built-in amplification) or passive (requiring an external amplifier or receiver).
-
Multi channel system
This is a speaker system that consists of more than two speakers (usually five or more) that are designed to reproduce surround sound. A multi-channel system always includes a subwoofer (or an LFE channel) to provide low-frequency effects. A multi-channel system can be wired (requiring speaker wires and an external amplifier or receiver) or wireless (using wireless speakers and a transmitter or hub).
-
Dolby
This is a company that develops audio technologies and formats for various applications, including cinema, broadcast, gaming, music, and home entertainment. Dolby is known for its surround sound formats, such as Dolby Digital, Dolby Atmos, Dolby TrueHD, Dolby Pro Logic, etc. Dolby formats use audio compression and encoding techniques to deliver high-quality surround sound with minimal data loss.
-
DTS
This is another company that develops audio technologies and formats for various applications, including cinema, broadcast, gaming, music, and home entertainment. DTS is also known for its surround sound formats, such as DTS-HD Master Audio, DTS:X, DTS Neural:X, DTS Virtual:X, etc. DTS formats use audio compression and encoding techniques to deliver high-quality surround sound with minimal data loss.

Essential Parts of a Multi Channel Home Theater System
What are the main components of a multi channel home theater system and how do they work together? Here are the essential parts that you need to have for a complete system:
-
Speakers
These are the devices that convert electrical signals into sound waves that you can hear. Speakers come in different sizes, shapes, designs, and types. The most common types of speakers for a multi-channel home theater system are:
-
Center channel speaker
This is the speaker that is placed in the center of the front wall or below or above the TV or the projector screen. This speaker is responsible for reproducing most of the dialogue and the vocals in the content. This speaker should be matched with the front speakers in terms of size and quality.
-
Front speakers
These are the speakers that are placed on the left and right sides of the center speaker or the TV or the projector screen. These speakers are responsible for reproducing most of the music and the sound effects in the content. These speakers should be matched with each other in terms of size and quality.
-
Surround speakers
These are the speakers that are placed on the left and right sides of the listening position or slightly behind it. These speakers are responsible for reproducing the ambient sounds and the directional cues in the content. These speakers can be smaller and less powerful than the front speakers.
-
Rear speakers
These are optional speakers that are placed behind the listening position. These speakers are responsible for adding more depth and realism to the soundstage by reproducing more ambient sounds and directional cues in the content. These speakers can be smaller and less powerful than the surround speakers.
-
Height speakers
These are optional speakers that are placed above or on top of the front or surround speakers. These speakers are responsible for creating a three-dimensional soundstage by reproducing sounds that come from above or below in the content. These speakers can be smaller and less powerful than the front or surround speakers.
-
Subwoofer
This is a speaker that is designed to reproduce low-frequency sounds (bass) in the content. A subwoofer can be placed anywhere in the room as long as it does not cause unwanted vibrations or resonances. A subwoofer should be matched with the other speakers in terms of power and quality.
-
-
Amplifier or Receiver
This is a device that amplifies (increases) the electrical signals from the audio source and sends them to the speakers. An amplifier or a receiver also acts as a switcher that allows you to select different audio sources and formats. An amplifier or a receiver also acts as a processor that allows you to adjust different sound settings and modes. An amplifier or a receiver should have enough power and channels to drive all your speakers.
-
Audio Source
- This is a device that provides audio content for your multi-channel home theater system. An audio source can be a physical media player (such as a Blu-ray player, a DVD player, a CD player, etc.), a streaming device (such as a smart TV, a media box, a gaming console, etc.), or an online service (such as Netflix, Spotify, YouTube, etc.). An audio source should support various audio formats and have compatible outputs with your amplifier or receiver.
-
Display Device
- This is an optional device that provides video content for your multi-channel home theater system. A display device can be a TV or a projector that shows images from your audio source or from another video source (such as a camera, a computer, a smartphone, etc.). A display device should have high resolution and contrast ratio and have compatible inputs with your audio source.
