Speaker Placement
Correct speaker placement is important to maximize the sound quality of your audio
system. Read this section for placement tips for your individual speakers, as well as
diagrams and descriptions of various speaker system layouts.
Positioning the speakers
Tower speakers
The tower speakers can be used as front-right and front-left speakers or as surround
speakers. Your inal speaker placement will depend on the environment and personal
listening preferences.
Follow these general best practices when placing your tower speakers:
• Place the speakers as far apart from each other as they are from the main listening
area. See the diagrams on page 16 for reference.
• Do not place the speakers any closer than 6 inches to any wall.
• If possible, keep the speakers about 2.5 feet away from the back or side walls.
• If the relection of the rear speakers off of the front wall is too strong, try pulling
the speakers away from the wall or switching the array to forward-focus mode. For
more information, see page 20.
• Start with the speakers placed parallel with your back wall, and experiment with
the imaging by increasing the angle (toe-in) until you ind the desired balance of
ambience and direct sound.
>6” (15 cm)

14
Center speakers
The most popular placement for your center speaker is just below and centered with
your TV. You can also place the speaker above your TV. Your inal speaker placement
will depend on the environment and personal listening preferences.
Follow these general best practices when placing your center speakers:
• Place the speaker as close to the center of your TV as possible.
• If the speaker is placed on furniture, keep the speaker lush with the front edge of
the surface.
Note: The DM20 speaker is designed for wall-mounting, if desired. However, do
not attempt to mount DM10 or DM30 speakers on a wall.
• If possible, angle the speaker toward the listening area if the speaker is too far
above or below your TV.
• Avoid enclosing the DM30 or DM10 speakers inside a cabinet. These speakers
have up-iring woofers and/or bass radiators. If your speaker is inside a cabinet, try
to allow at least a few inches between the top of the speaker and the cabinet.

15
Surround and height speakers
You can use the DM95 speakers as surround or height speakers. Review the Quick
Start Guide that came with the product for installation instructions. See below for
additional placement advice, depending on your setup.
For more information about using and positioning height-channel speakers for Dolby
Atmos, visit https://www.dolby.com/.
Follow these general best practices when using DM95s as surround speakers:
• Position the speakers on side walls, slightly behind and above the listening area.
• Position the speakers so that the tweeters point toward the listening area.
• If you install a second pair of DM95 speakers, mount them where they are best
able to face the listening area.
Note: Two DM95 speakers can be used for the surround channels in a 5.1 setup or
four can be used as surround and surround back channels in a 7.1 system.
Follow these general best practices when using DM95s as height-channel
speakers:
• Position the speakers so that the tweeters point toward the listening area.
• If you are using two DM95 speakers, you can mount the speakers above the
left-front and right-front speakers or to the sides (as seen in the diagram above),
depending on the room and your preferences. For detailed information and place-
ment suggestions with two or more height-channel speakers,
visit https://www.dolby.com/.
As with the tower and center speaker placement, your inal surround height speaker
placement will depend on the environment and personal listening preferences.

16
Speaker system setups
Your Dymension speakers are compatible with 2, 3, 5, 7, and 9-channel surround
sound conigurations and all Dolby Atmos setups (for example, 5.1.2, 5.1.4, etc). Take a
look at the following examples and give them a try based on the Dymension speakers
you have.
Note: You can add DM90 height modules or wall-mounted DM95 speakers to the 5
and 7-channel systems described below to enable a new dimension of immersion to
your home theater experience when using Dolby Atmos, DTS:X, etc.

Get the most realistic stereo image by placing the speakers as far apart as the listen-

distance of the speakers from the back wall. For more information, see page 20.

You can use DM95 speakers as rear surround speakers to create a home theater sur-

above the listening position.
Note: If you cannot place rear surround speakers along the side walls, position them
along the rear wall above the listening position.

Speaker Wiring
All of the Dymension series speakers use the same binding posts that can be un-
screwed and then tightened to connect bare speaker wire. You can also attach a
banana plug or spade connector to connect wire to the binding posts. See the next
sections for wiring illustrations.
To connect bare speaker wire to the binding posts on your Dymension speaker:
1. Strip about 3/8 in (10 mm) of insulation from two speaker wires.
2. Unscrew the binding posts.
3. Insert the wires through the binding posts.
4. Tighten the binding posts until secure.

The DM70 and DM80 speakers come with more than one set of binding posts. As
seen in the diagrams, the bottom pair of binding posts connect the main speaker
array. The top pair of binding posts are used to connect a DM90 height module to
your receiver. For more information about the other binding posts and wiring options
for DM80, see page 27.

The Rear Speaker Array
The Dymension tower speakers each come with a rear speaker array. These
speakers can be adjusted down if there is too much spatial effect. DM70,
DM60, and DM40 use a switch to adjust the level of the rear tweeter. DM80
uses a jumper cable to attenuate the entire array.
How does the rear array work?
The tower loudspeakers have speakers iring forward and rearward in what’s known as
a bipolar array. This enhances spaciousness and immersion by directing more energy
into the room than a typical loudspeaker does. Below is an illustration of this sound
radiation pattern.
The amount of increased ambience and immersion can be adjusted if desired in
several ways.
To adjust the spatial effect from the rear array:
• Move the speakers farther from or closer to the wall. The closer to the wall, the
stronger the contribution from the rear speakers will be.
• Toe in the speakers or align them parallel with the wall. More toe-in will decrease
the contribution from the rear speakers.
• Switch the rear array between 0dB (full bi-polar) mode or -6dB (forward-focused)
mode. See the next page for more information.
