Dolby Atmos speaker setups: What the 7.1.4 description means 7 This refers to the number of traditional surround speakers (front, center, and surround).1 The middle number refers to how many powered subwoofers you can connect to your receiver.4 The final number refers to how many in-ceiling or upward-firing speakers are in your Dolby Atmos® setup. The configurations noted in this guide are illustrative. We recommend that any overhead speaker installation be performed by professional installers with experience in installing overhead speakers.
If you're using Dolby Atmos enabled speakers, place them at the left front and right front locations, and at the left rear and right rear surround locations. If you're using add-on modules, place them on top of the left front, right front, left rear surround, and right rear surround speakers, or within three feet of those speakers. Be sure the drivers are facing toward the ceiling. You'll get the best sound when the front and surround speakers are at or slightly above your ear level when you're seated. Wall-mounted surrounds can be higher, but no speakers—especially Dolby Atmos enabled modules—should be higher than half the height of your wall. The angles shown in all diagrams represent the ideal placement range relative to your listening position.

Ceiling Height and Materials The ideal ceiling height is between 7.5 and 12 feet, and the maximum recommended height is 14 feet. The ceiling should be flat and made from an acoustically reflective material, such as drywall or plaster.
Ceiling Speaker Calculator Guide The Speaker Calculator help page provides detailed descriptions of the parameters in the user data fields, the calculation results, and the coverage map. This guide assists in understanding the information necessary to calculate the number of ceiling speakers needed for a room or listening area, and to effectively apply the Speaker Calculator recommendations to a sound reinforcement system design. A Note on Data Entry The Speaker Calculator is simple to navigate. Pressing the key allows you to efficiently progress through the data fields as you enter the parameters. Use to move backwards through previous entries. Once the information has been entered, press the Calculate button to view the speaker quantity recommendation as well as amplifier power requirements.
You can revise any of the input parameters and then update the results by pressing the Calculate button. User Data Fields Select Unit of Distance Measurement – Allows you to define the unit of measurement in feet or meters, for the user input parameters as well as the calculation results.
Room Length – Approximate length of the coverage area. The coverage area can be a room, or a specific area in the room where listeners will be situated. Room Width – Approximate width of the coverage area. Speaker Height – Approximate height at which the speakers will be installed. In most cases, this will be the height of the ceiling. The value entered must be greater than 7 feet (2.13 m). Listener Height – This is the ear height of a typical listener.
Consider whether the typical listener will be seated or standing. The default value is 4 feet (1.22 m), which is typical for seated listeners. For standing listeners, 5.5 feet (1.68 m) is the typical ear height. The maximum value that can be entered is 1 foot (0.3 m) below the speaker height value. Advanced Options Hidden from view are five optional parameters that may be left at their default settings for most estimation projects.

Force Grid Spacing – Allows the user to define a ceiling grid spacing distance, and effectively force the speakers into a pattern that will match ceiling tile spacing. The default value is 0, which provides ideal speaker locations without alignment to any grid pattern. Defining a specific value will constrain speaker spacing to multiples of the grid spacing distance.
This may introduce a degree of error in the calculations, resulting in the need for additional speakers to compensate. The greater the grid spacing distance, the greater the chance of error introduced. Ambient Noise (dB SPL) – This is the amount of background noise within the environment.

The default setting is 50 dB SPL and the maximum value that can be entered is 90 dB SPL. The following are common environments and their typical ambient noise levels: Environment Typical Ambient Noise Level (dB SPL) Videoconference room 35 Quiet library/residence 40 Quiet office/empty classroom 50 Busy restaurant 60 Noisy office 70 Busy cafeteria 80 Airplane cabin 90 Desired S/N (dB) – The desired sound pressure level (SPL) of the audio system above the specified ambient noise. This signal-to-noise ratio will define the intelligibility of the audio system. The default setting is 25 dB. The user can increase this value to provide additional margin above the ambient noise, and enhance intelligibility.

Minimum Needed Level (dB SPL) – This field displays the sum of the ambient noise and desired S/N, and represents the target sound pressure level for baseline intelligibility. This parameter will be used to calculate the minimum amplifier power necessary to drive the speakers. Maximum Target Level (dB SPL) – This allows the user to target a specific maximum sound pressure level, to ensure adequate system headroom for the loudest anticipated sounds.
Some common audio sources and their typical SPL values are listed in the following table: Audio Source Typical SPL (dB) Whisper 20 Soft stereo in a residence 40 Very soft music 50 Conversational speech 60 Soft classical music 65 Vacuum cleaner 70 Soft popular music 75 Alarm clock 80 Moderately loud classical music 85 City traffic 90 Loud classical music 95 Firecrackers, subway train 100 Speaker – Select the speaker you wish to design into your project. The Speaker Calculator includes all current Extron ceiling speaker models, with the exception of the Extron SI 26X ceiling speaker.
