Page 8 • User Manual • Mounting & Placement

Monitor mounting and placement is often an afterthought, but in order to get

the best imaging and overall performance from the SAT 8, it is important to

place the speakers correctly.

Monitoring Height:

Figure 1 shows the ideal monitoring height, with the SAT 8

located perfectly at seated ear height. If this is not possible,

tilting the cabinet at the listening area can improve high-frequency

coverage.

Monitoring Angle:

The recommended position for the monitors is based on an ITU

standard and sets the speakers at 60 degrees from the listener,

forming an equilateral triangle (a triangle with equal sides) - See

Figure 2. Fortunately, this setup eliminates most of the math and

is easily simpliﬁed to the following guidelines: If you want to sit 2

meters from the speakers, place the speakers 2 meters apart. If

you want to sit 9 ft. from the speakers, place the speakers 9 ft.

apart Etc.

Wall Mount Options:

The SAT 8 is compatible with OmiMount® 60 Series brackets,

via the 1/4 X 20 inserts located in the bottom and the back

of the cabinet. The OmniMount® 60 brackets are designed

to support up to 60 pounds of weight when properly installed.

Please visit www.omnimount.com for more information,

including detailed mounting instructions. Please see page 13

[Technical Speciﬁcations & Dimensions] for more information on

insert locations. Also see page 3 [Safety Instructions] item 17

“MOUNTING”.

Mounting the SAT 8 in a bafﬂe wall / sofﬁt:

IMPORTANT: It is highly recommended that you check all of your

local electrical and safety codes, to make sure that all regulations

are going to be met before mounting the SAT 8 in a bafﬂe wall.

Requirements and recommendations:

1) Important Requirement: Proper cooling and airﬂow shall be

provided to the back of the SAT 8 / Heatsink.

2) Recommendation: In order to build an affective bafﬂe wall,

it is best to use a design with considerable mass, that doesn’t

produce sympathetic resonances. Using three layers of 5/8” (50

mm) Gypsum, with overlapped joints, and the appropriate wood

framing has been found to be affective (again, consult local

building codes and an engineer or architect for speciﬁc design

guidelines).

3) Recommendation: To avoid sympathetic vibrations, it is best

to physically decouple the SAT 8 from the bafﬂe wall structure.

An effective way to do this is to use Mason Super W neoprene or

natural rubber pads (durometer 40). One Super W pad should be

placed under each corner of the speaker.

4) Recommendation: Mount the SAT 8 ﬂush with the front of the

bafﬂe wall and seal all gaps around the SAT 8 and the bafﬂe

wall using a rubber, foam or neoprene gasket material. This will

improve the HF frequency response, by reducing any cabinet or

edge diffraction related problems (again, check local building

codes).

5) Recommendation: The SAT 8 includes four primary bafﬂe

compensation settings, each of which reduces the MF to LF

“bump” that typically results from mounting a speaker in a bafﬂe

wall. The amount of compensation needed is dependent on room

acoustics and the size and type of bafﬂe wall. The only way to

accurately determine the amount of compensation needed is to

use a high resolution acoustic analyzer, such as MLSSA, TEF, etc.

For more information please see page 6 & 7 [A Tour of the SAT 8

Ampliﬁer & Electronics] and page 14 [Measurement Data].

Mounting the SAT 8 behind an acoustical transparent screen:

If you intend to place the SAT 8 behind an acoustically transparent

screen, it is recommend that you use a screen that provides the

minimum amount of acoustic loss at high frequencies, such as

the Microperf screens offered by Stewart Filmscreen (www.

stewartﬁlmscreen.com). Additionally, it is also recommended

that you add some acoustically absorptive material to the wall

behind the screen, to help absorb HF reﬂection from the screen.

Typically 2” of black duct liner, or other ﬁberglass acoustical

blanket can work well (check local building and safety codes for

possible restrictions and guidelines).
