Best surround sound system for projector
A projector needs a good surround sound system to fully enjoy the projector experience. Below are some of the best surround sound system to setup for a home Projector
5.1 or 7.1 Surround Sound Systems for home Projector
5.1 and 7.1 surround sound systems have multiple speakers placed in strategic locations around you when watching a projector screen. The picture here shows the locations of the placement for a 5.1 surround sound system. For a 7.1 surround sound, there will be extra 2 speakers placed behind the viewer.
The surround sound system setup for a projector is the same as in the picture below where a TV is shown instead of a projector. The center speaker should be placed under the screen in the case of projector surround sound.
How 5.1 surround sound works
The various speakers in a surround sound system have different functions as explained here:
Center speaker in 5.1 surround sound system
The sound of conversation are output from the center speaker placed just below the projector screen. This gives you the feeling it is actually the people on the screen who are speaking. It is important that the center speaker of a 5.1 or 7.1 surround system is of the best quality you can afford, because it is from this front central speakers that all voices of conversation comes and good quality speakers are essential to hear it clearly.
Front left and right surround speakers in 5.1 system
These speakers output sounds that come from the left and right sides of a TV picture. Let us take an example of a car moving from left to right in a TV scene.
The sound is higher from the left center speaker when the car is just entering the picture from the left side. As the car moves to the center of the screen, the sound from the front left speaker reduces, the sound from the front center speaker is at the maximum and when the car reaches the right side of the screen, the sound from the front right speaker increases. The car passes across the TV screen in a couple of seconds if moving slowly, or will flash across the screen in a split second if moving fast. Whatever the speed of the car, the speakers are synchronized with the movement of the car and you get that very realistic sound of the car flashing across your screen.
Rear Speakers Left and Right in 5.1 sound system
The rear left and right speakers in a 5.1 or 7.1 surround sound system comes into play when the projector scenes require sound from the rear or from all around you. Examples of scenes when all speakers come together are for example when there is heavy rain, you will feel you are caught up in the rain. Rear speakers also come into its own when for example a plane flies past you overhead. You have to experience quality surround sound system to really enjoy modern HDTV movies.
Subwoofer in 5.1 sound system
The Subwoofer is the sixth speaker in a 5.1 surround sound system and the .1 in the 5.1 is what the sub-woofer is represented by. The subwoofer's job is to output all the low frequency sounds, like explosions, heavy drums, very deep bass sound of a conversation, etc. Since human ears cannot make out the direction from which the low frequency sound comes from, the sub-woofer can be placed anywhere in the room.
What is Dolby Atmos Sound System
Dolby Atmos sound system is similar to the 5.1 or 7.1 surround sound system with the addition of overhead speakers to give sound from the top. This creates a 3D sound effect and no words can describe the fantastic sound effects.
Dolby introduced the Dolby Atmos Sound system in 2012 and the first movie recorded in this new Atmos surround sound was the 'Brave'. The first movie theatre with Dolby Atmos Surround system is in Hollywood, the 'Dolby Theatre', the famous venue of the annual Oscar Awards ceremony.
Dolby Atmos sound is what the latest high budget Hollywood movies are recorded in. If you have seen a movie with Dolby Atmos sound, then you know what we are talking about. It is sound technology at its pinnacle. Nothing comes close to it.
Now we can experience this fantastic surround sound in our home theater systems at home. Our existing surround speakers can be used and the price for setting up a Dolby Atmos surround system at home is not that expensive. The video below from ONKYO demonstrates what Dolby Atmos surround sound is and also explains how it is possible to convert existing 5.1 and 7.1 ordinary surround sound systems.
Famous Audio Companies like Denon, Marantz, Onkyo, Pioneer and Yamaha have many new Dolby Atmos Audio Receivers, either stand alone Dolby Atmos Receivers or as Dolby Atmos Home Theatre in a Box (HTIB) complete with receiver and all the required speakers.

The new Dolby Atmos home audio system can be either the standard 5.1 or 7.1 surround sound speaker systems with the addition of either 2 or 4 over head speakers. When 2 overhead speakers are used in a 5.1 surround sound speaker system, it becomes a 5.1.2 Dolby Atmos surround sound speaker system and if 4 overhead speakers are used it becomes a 5.1.4 Dolby Atmos surround sound speaker system. Similarly with the use of 2 or 4 overhead speakers in a 7.1 surround sound system becomes a 7.1.2 or 7.1.4 Dolby Atmos surround sound system.
Soundbars for projectors good or bad
Soundbars are an easy to install surround sound system consisting of just two pieces of equipment, the soundbar itself and a subwoofer.
The amplifier is built into the long sound bar which is kept in the same position as the central speaker in a 5.1 surround system. There is no complicated wiring to be done, just to connect the sound output from the DVD, Blu-ray player or STB directly to the soundbar and you are all set to go.
Sound bars have many focused speakers that sends out focused beams of sound, much like beams of light, and these focused beams of sound gets reflected off the walls around you to give the same effect as the 5 surround sound speakers in a 5.1 surround sound system.
