What makes a good Home Theatre System?


A good home theatre system should be an immersive experience, not just something you see and hear, but something you feel, it should blow your mind and take your breath away.

A home theatre system needs to process audio in a different way to music with more emphasis on the lower frequency effects and ensuring that the correct audio effects are distributed to the correct speakers with the majority of the voice audio being sent to the front centre speaker for the ultimate experience.

A home theatre system must not only process audio, but also produce quality video, ensuring that the image and the sound track are in perfect sync with each other.

Ideally the room utilised as the home theatre should be custom built, being the correct shape and possessing the ultimate acoustics, just enough sound absorption and not too much echo, but this is not always possible, so a good home theatre system must be able to adapt to it’s surroundings producing the best possible sound under the circumstances in which it is installed, this is called optimisation and something a good home theatre installer will do for you.

Bigger and more powerful is not necessarily always better, but depends on the size of the room where the system will be installed and naturally your budget, our highly experienced professionals will be able to advise you accordingly.

A complete home theatre system is made up of various components and all these components need to be compatible with, and complement, each other. We have the source device which would be your DVD or Blu-ray player, the AV receiver receives the signal from the source device and distributes the video to your TV or Projector and the audio to your speakers, the system as a whole is only as good as it’s weakest component, this includes the quality and type of cables used to connect the various devices.

Each component needs to be carefully selected to ensure that the overall system operates to it’s full potential.

The Different Components of a Home Theatre System.

A home theatre system is a visual as well as an audio experience. The choice of video output devices is huge, but basically split into two primary types, A TV or Projector.

TV's are generally the more popular choice for most people owing to their greater versatility and practicality, you can watch TV without having to use the Home Theatre system for audio and TV’s are not affected by ambient light as much as Projectors are, projectors also require greater maintenance as the bulbs have fairly limited life span and can be expensive, but projectors are the preferred choice in professional home theatres owing to the increased screen size.

A good Home Theatre system should be capable of receiving input from numerous sources, DSTV decoder, Blu-ray or DVD player as well as game consoles and media players etc.

Having quality input devices is the starting point of a good overall system with HDMI outputs being the basic minimum of a modern system, we highly recommend a good quality Blu-ray player.

The AV Receiver is the heart of the overall home theatre system. It must be able to receive the signals from the source devices and output the video to the TV and the audio to the speakers.

A good AV receiver should not only be powerful, but be able to receive inputs from multiple HDMI, digital and analogue

Most of us believe that to get the best quality sound, or volume, we have to purchase the most powerful AV receiver.

Yes, the power output and quality of the AV receiver does play a role but it is ultimately the job of the speakers to convert that electrical power into quality sound.
Poor quality, inefficient, speakers have to be driven harder by the amp to get similar volume, placing greater strain on the amp. Quality speakers reproduce a more true sound resulting in a better listening experience even at lower volumes.

Modern TV’s are not only getting bigger, but also becoming smarter offering 3D and Ultra High Definition picture quality. Ultimately your choice of Video output depends on your budget, but ensure that whatever TV/Projector you choose is compatible with your other Home Theatre devices, there’s no point in purchasing a 3D TV when your Blu-ray player or AV Receiver does not support this function.

devices and should be able to switch between the inputs. The AV Receiver needs to be compatible with the type of input it is receiving, 3D, HDMI or Ultra High Definition.

An AV Receiver is normally capable of at least 5.1 audio output, which means it can support a front centre, two fronts, two rear speakers and a sub woofer, but modern movies are being produced in much greater audio detail now requiring 11.2 and Dolby Atmos.
