Monitor mounting and placement is often an afterthought, but in order to
get the best imaging and overall performance from the SAT 6.5 EXR, it is
important to place the speakers correctly.
Monitoring Height:
Figure 1 shows the ideal monitoring height, with the SAT 6.5
EXR located perfectly at seated ear height, with the cabinet in
recommended vertical configuration. If this is not possible, tilting
or aiming 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 6.5 EXR is compatible with OmiMount® 60 Series
brackets, via the 1/4 X 20 inserts located on the bottom 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 6.5 EXR 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 6.5 EXR in a baffle
wall.
Requirements and recommendations:
1) Important Requirement: Proper cooling and airflow shall be
provided to the back of the SAT 6.5 EXR / 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 6.5 EXR 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 6.5 EXR flush with the front
of the baffle wall and seal all gaps around the SAT 6.5 EXR 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 6.5 EXR 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 6.5 EXR Amplifier & Electronics].
Mounting the SAT 6.5 EXR behind an acoustical transparent
screen:
If you intend to place the SAT 6.5 EXR 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 front of 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).
