The Difference Between a Home Theatre and Home Cinema
Home Theatre - (Media Room) is a flexible multipurpose space kitted with large television, surround sound and comfortable seating. A media room is more flexible for people who want to do more than sit in the dark and watch a film. The seating is not fixed but moveable, so the room can double as living room.
Home Cinema on the other hand is a dedicated room that offers fantastic audio and video experience. It usually has a large screen and a projector. A Home Cinema does not double as a Living Room or family room.
Dolby Atmos® Speaker Placement Explained
Strangely enough, there are actually more options for speaker placements in a room than there are flat panel tv screen sizes! In today’s world of immersive home theater, you may have seen number sequences like 7.1.4 or 5.2 or 3.0. It really helps to understand these abbreviations as you are going to see them pop up when you start researching home theater receivers.
Decoding this sequence is very easy once you know the key! The first digit is the number of speakers in the room that are not Dolby Atmos speakers. Dolby Atmos speakers either go in the ceiling or on top of your main speakers to fire up and bounce off the ceiling. So, if the first digit is a 5, for example, this means there is a left, center, right, and a pair of surround speakers.
The next digit is the number of subwoofers. You will normally see most configurations just call out for one subwoofer, but we highly recommend at least 2 for a serious home theater room.
The third digit is the number of Dolby Atmos speakers. These can be either in the ceiling aiming down or what is called an elevation speaker that sits on top of your main front and if you do 4 your rear speakers and fire the sound up towards the ceiling. There are now even tower speakers with the upward firing speakers built into the top. Today’s home theater receivers let you tell them which type of Dolby Atmos speaker you are using to keep the sounds perfect.
To decode this one: 5.2.4 = 5 main speakers, front right, front left, center, right surround, left surround, 2 subwoofers and 4 Dolby Atmos speakers.
Most home theater receivers max out at 11 channels, which enables a 7.1.4 setup. There are a few on the very top end of the price scale that allow you to do 9.1.4 and even 11.1.6. For the purposes of this help guide, we will stop at 7.1.4 as for most rooms that is more than enough for an amazing experience!
Main - Surround - Rear - Subs
As you go through these different configurations, keep in mind you’ll have choices on what type of speaker to use. For the main speakers, surround speakers, and rear speakers you can use an in-room tower or bookshelf speaker, an on-wall speaker or an in-wall speaker. The Dolby Atmos speakers can be either an in-ceiling speaker or an elevation speaker that would sit on top of your tower or bookshelf speaker.
You may wind up laying out the perfect room only to find the way your room is constructed does not allow you to put speakers exactly where they should go. This is especially true for ceiling and in-wall speakers. For in ceiling Atmos speakers, if you have a beam in the way, we find it better to move them to the left or right rather than front to back to find the spot where they can fit in the ceiling between the beams. For side speakers, we will usually suggest you move them slightly backwards, and for rears, move them further apart than closer together.
In some instances, it may not even be possible to have the speakers symmetrical. In this case, don’t give up, just follow our suggestions and bear in mind all of the decent surround sound receivers will let you compensate for different speaker distances. It's better to be off a little than to have no speaker at all!
We will start with the layout we consider the best choice and work down from there. And as if we have not said it enough, these all show just one subwoofer, but in our opinion, you can never have too many subwoofers! Work down from there, with advice on each one.
7.1.4 - Seven channels plus 4 Dolby Atmos Speakers – Ultimate
With this great setup, we have 3 front channels, a pair of side surrounds, a pair of rear surrounds, and 4 Dolby Atmos speakers. For the ultimate, we recommend going with in-ceiling speakers for Dolby Atmos. However, if it is not possible to get the wiring to your ceiling, most speaker brands make a Dolby Atmos elevation speaker you can place on top of your front and rear speakers to reflect the effects off the ceiling. Here we show options for both in-ceiling and upward-firing elevation Atmos speakers.
For this configuration, you’ll need a home theater receiver that supports Dolby Atmos with 11 powered channels or a separate surround sound processor and 11 channels of amps. You’ll find a decent variety of these on the market today. This will give you the ultimate in Dolby Atmos sound quality.
Main Left Center Right
You will want to position your main left and right speakers at anywhere between a 45 to 60-degree angle to your listening position. The center channel should be centered on your screen. Ideally, the height of your left, right and center will be at ear level. While this is not always possible, especially with a big flat-panel television, you can put the center channel just below the TV.
With Dolby Atmos, you want your main side surrounds to be at ear level and in line with your ears. If you do not have another row of seats on a riser behind the main level, the rear surround speakers should be at ear level as well. The rear speakers are like the front speakers and should be spread out at a 45 angle if possible. Positioning the surround speakers at ear level combined with in-ceiling or upward-firing Atmos speakers gives you an amazing surround effect.
One thing to keep in mind is if your seating is close to the back wall, when you map out a 60 degree spread the rear speakers may still be very close together, in this case, position them to just outside of the main seating area.
For in-ceiling Atmos speakers, we feel they work best spread at a 90-degree angle from the main seats when looking at them from the side. They should be in line with your left and right main front speakers.
For elevation Atmos speakers (or Dolby Atmos-enabled speakers), simply place them on top of your front left and right speakers and rear left and right speakers.
5.1.4 - 5 Channels + 4 Dolby Atmos Speakers
We are commonly asked, "Should a theater have one pair of Atmos speakers and both side and rear surrounds OR two pair of Atmos speakers and one surround pair?"
We are also asked, "Should you put one pair of surrounds on the sides or in the rear?" We prefer the 5.1.4 layout over what would be a 7.1.2 layout. We also feel that if you are going with Dolby Atmos, you want the one pair of surrounds to be on the sides. This type of system will need a home theater receiver with 9 powered channels on board. We see a lot of rooms where getting a pair of rear speakers is not possible. This is by far and away the best surround sound solution for a room with those limitations.
Main – Left – Center – Right
The surround sound speakers should be at ear level and at about a 110-degree angle, putting them just behind your listening position. For Atmos Speakers you can use the same tips for 7.1.4
7.1.2 - Seven channels plus 2 Dolby Atmos Speakers
We see many existing home theater systems where there are already seven speakers in the room. If you have this type of layout and want to add Atmos but only do one pair, this is a great option.
A 7.1.2 configuration will require a home theater receiver with 9 powered channels, just like a 5.1.4 would. We do, however, recommend a 5.1.4 or 7.1.4 layout if you are starting from scratch.
Main – Left – Center - Right
For the surround Speakers you will use the same tips as 7.1.4
For a single pair of Atmos in-ceiling speakers, they should be positioned at about an 80-degree angle from the primary position as shown in the drawing when looked at from the side. This is basically 10 degrees off a straight line drawn up from your ears which puts them slightly in front of your listening spot. They should be in line with your front left and right speakers.
For elevation Atmos speakers, simply place them on top of your front left and right speakers.
5.1.2 - Five channels plus 2 Dolby Atmos Speakers - Most Popular
Main - Left – Center – Right.
For Surround Speakers Use the same tips as 5.1.4 and for Atmos Speakers use the same tips as 7.1.2
7.1 - Seven channels with no Dolby Atmos
Main – Left - Center - Right
And for Surround Speakers This is a case where we recommend that you raise the side speakers up to help give you more of a full surround effect. About 6 feet off the floor usually works out well. Or, as we show here, you can use an in-ceiling speaker - however, the only reason you would want to do the in-ceiling is if you do not have a Dolby Atmos-enabled receiver. If you did, do Atmos! The rear speakers should be mounted at or around ear level to improve the surround effect with the upper placed side speakers. Again, this is more of a legacy layout and is only recommended when you have either equipment or room constraints.
5.1 - Five channels with no Dolby Atmos
Main – Left - Center – Right
And for the Surround Speakers in this system, since we have no rears or Atmos heights, we like to see the surrounds placed a little bit behind your head and anywhere between ear level and about 6 feet off the floor. Or, you could go with an in-ceiling speaker just behind the main seats. Again, if you can do a Dolby Atmos based system with more speakers, we highly recommend it, but some rooms just do not allow us the flexibility for the speakers we need.
Surround sound has many types of speaker options which are expressed in a 3 digit format. Getting your speaker placement right will greatly benefit your surround sound experience.
The 7.1.4 setup with 7 speakers at ear level, 4 Atmos speakers, and one or more subwoofers can provide the ultimate surround sound experience in most rooms. The 5.1.2 speaker configuration is the most popular and best value with 5 speakers at ear level, one pair of Atmos speakers, and one subwoofer.
