When You Have Purchased
the Pantheon System
Yourauthorized Gryphon dea-
ler delivers and installs the
Pantheon system. His staff
has been meticulously schoo-
led in the proper unpacking of
the system and in the set-up
of the system. Your dealer will
return after a two-week
break-in period for final
adjustment.
After three months, your dea-
ler will come back for a final
check-up.
This service is included in the
price of the Pantheon system
and is crucial to optimizing
system performance.
The Listening Room
This section outlines ideal
room dimensions and speaker
placement. Specific acoustic
conditions may permit some
deviation from these recom-
mendations. Pantheon curved
baffle is designed so that the
sound from all drivers integra-
tes at a point 5 m in front of
the high frequency driver.
(Think of the drivers as rows
of spotlights all angled to illu-
minate the same spot.)
The cabinerts should be at
least 1 m from any side wall.
We recommend as much dis-
tance from the backwall as
possible.
Imagine a circle on the floor
at a diameter of 10 meters
with the listener in the middle.
The Pantheon should be set
up following the line of this
circle forcing all the drivers to
point direct at the listener at a
distance of 5 meters. This is
the basic designformula and
not all locations will allow this.
We have tested Pantheon in a
number of different room
sizes from very small rooms to
halls. What is important is in
all cases to set the speakers
up with a toe- in pointing
direct at the listener.
Note: plush furnishings provi-
de high acoustic damping,
requiring greater system out-
put.
Pantheon was developed in a
50 sq.m. room with typical
acoustic damping correspon-
ding to most modern residen-
tial spaces.
We do NOT recommend room
treatments for added damping
behind the loudspeakers.
Some damping behind the lis-
tening position is recommen-
ded, especially if it is close to
the rear wall.
Diffusion is generally a far
better acoustic solution in that
it removes unwanted reflec-
tions without restricting dyna-
mics or exerting excessive
influence on tonal balance.
Because Pantheon design
requires angling the cabinets
in towards the listener, the
influence of side walls is mini-
mal. The curved baffles also
reduce reflections from floor
and ceiling. If the ceiling is
low, a diffuser placed at the
point of the first reflection
may be useful. A rug on the
floor between listener and
speakers will help. The con-
ventional coffee table in front
of the listener is typically the
source of most problems with
unwanted reflections.
We strongly suggest that all
effort are made to optimize
