Introduction to the Dolby DSR1090 Speaker
The DSR1090 is a high-performance cinema surround speaker for use in 5.1 and Dolby Surround 7.1
cinema auditoriums, as well as small to medium-sized Dolby Atmos equipped auditoriums. The
DSR1090 provides a 90° horizontal ✕ 60° vertical acoustic coverage pattern, which works well for
general-purpose surround applications and can be used for sidewall or overhead installations.
The DSR1090 utilizes a high-performance 10-inch low-frequency driver and a 1-inch exit high-
frequency compression driver. Both transducers are finite element modeling (FEM) optimized, which
allows the transducers to deliver high-sound pressure levels with minimal distortion. These advanced
drivers, coupled with the Dolby industry-leading system design and support philosophy, allow for
exceptional performance, and quick, easy installation and service.

2.1 About this documentation
This documentation describes the key features and benefits of the Dolby DSR1090, provides important
preinstallation information, and shows you how to install the system in a typical cinematic exhibition
environment.
2.2 DSR1090 key features and benefits
The DSR1090 is a compact surround speaker for general-purpose cinematic exhibition that provides several
key features and benefits.
• The 90° horizontal ✕ 60° vertical acoustic coverage pattern provides good distribution of audio for small
to medium theaters.
• The advanced input plate features a high-current, spring-loaded terminal block that enables quick
installation without the need for spade lugs or a crimping tool.
• The high-frequency driver is a low-distortion 25.4 mm high-temperature polymer dome with a frequency
response up to 20 kHz.
• The low-frequency driver is a 10-inch transducer with a finite element modeling (FEM) optimized motor
and suspension, optimized cooling for low power compression, and a high excursion rating.
• An industry-standard four-hole mounting point on the rear of the enclosure allows for simplified and
flexible mounting solutions.
• Holes on the sides of the speaker cabinet are provided for installation of a mounting yoke.
2.3 DSR1090 preinstallation information
In a typical auditorium, the DSR1090 is installed in various locations throughout the auditorium, including
possible locations on side and rear walls, and overhead locations. Information is provided on the placement
of the DSR1090 in a standard auditorium and in a Dolby Atmos auditorium.
Figure 2: Standard Dolby Surround installation example (5.1/7/1)

2.3.1 Placing the DSR1090 on a wall or ceiling
You can attach the DSR1090 to a wall or ceiling.
For 5.1 or 7.1 Dolby Surround auditoriums, you should follow standard industry practices for speaker
placement and aiming. For Dolby Atmos auditoriums, follow the instructions in the
Dolby Atmos
Specification Guide
, which you can download at https://professional.dolby.com/siteassets/cinema-
products---documents/dolby-atmos-specifications.pdf.
2.3.2 Determining horizontal aiming for side and rear speakers
For Dolby 5.1 or 7.1 surround installations, there is no requirement for horizontal angling of the side and rear
surrounds when speakers point toward the central listening area (CLA).
For Dolby Atmos installations, to determine the proper horizontal aiming for the side and rear surround
speakers, you need to define a rectangle within the CLA that includes the reference listening position (RLP).
For side and rear surround speakers that are adjacent to the CLA, aim the speakers directly into the
auditorium (that is, 0° from perpendicular), ±10°.
For installations that utilize speaker pairing, splay the paired speakers to improve sound coverage. For all
speaker pairs, we recommend these aiming parameters, which are based on the CLA:
• Aim the forward-paired speaker to the near-side forward corner.
• Aim the rearward-paired speaker to the near-side rear corner.
The following figure is an example of proper horizontal aiming for side and rear speakers.
DSR1090 preinstallation information
Dolby DSR1090 Owner's Manual 9
Issue 1 Part number: 8800304 16 October 2022
Figure 4: Horizontal aiming for side and rear surrounds
2.3.3 Determining vertical aiming for side and rear speakers
For side and rear surround speakers, you should tilt the speakers vertically to orient the axis of each speaker
to the ear height of a seated listener in the farthest seat. You can aim the speaker higher, but not by more
than half the vertical coverage angle of the speaker. Typically, rear surround speakers should have the same
downward tilt. The tilt of the side surround speakers should not change abruptly (>10°) from speaker to
speaker along the array.
This figure is an example of side and rear vertical aiming.
Figure 5: Side and rear speakers vertical aiming
2.3.4 Determining the top surround position
You must always place top surround speakers as le/right pairs, with the le speaker and right speaker
located at the same distance from the front wall.
You must place the top surround speaker pairs symmetrically with respect to the screen center line. Typically,
the top surround arrays are placed in line with the le center and right center screen speakers.
We recommend wider spacing for tall auditoriums, which is also acceptable for typical auditoriums when
standard placement is unachievable. You should then determine the maximum width between top surround
speakers by elevation angles as follows, and is shown in the next figure:
