A. To try the speakers on different walls, set your equip-
ment in the middle of the room so the speaker cables
can reach each position.
B. When you change the placement of the speakers, listen
to several different pieces of music before judging the
results.
C. If you set the speakers on a wood floor, place a set of
Spikes Shoes under the cones to prevent damage to the
floor.
D. Double check the tilt and use a laser pointer on top of
the speaker to verify they both point at the same height
on the rear wall.
E. Check polarity of all the wires in the system and clean
all connections.
E. When you have discovered the optimum speaker posi-
tioning in your room, mark it with tape so you can move
the speakers to vacuum without loosing your placement
reference.
F. If the bass is ill-defined in your room regardless of
where you place the speakers, check your windows for
loose panes of glass. Loose glass will vibrate and can
seriously impair the low frequency detail of the system.
G. Keep notes on the sound at the different placements you
try. Its easy to get mixed-up and forget which place-
sounded the best.
H. Don’t over-analyze sound of each placement. When the
sound is right, it will be obvious.

EQUIREMENTS
The Model Treo is designed for use with amplifiers
rated at 40 to 200 watts per channel into 8 ohms. Amplifi-
ers in this power range will provide ample power for realis-
tic listening levels in most situations. Amplifiers with less
than 40 watts may not be able to drive the Model Treo to
realistic listening levels without stress, while amplifiers
with more than 200 watts must be used with caution due to
the increased potential for speaker damage if they are mis-
used or an accident occurs.
The Model Treo’s are very revealing speakers and are
easily capable of showing subtle sonic differences between
amplifiers. They will perform well with a tube,
transistor, or hybrid amplifier, allowing each design to real-
ize its full potential. The amplifier can be a quality re-
ceiver, integrated amplifier or separate amplifier. The sta-
ble impedance of the Model Treo reduces load induced
amplifier problems, expanding the possible amplifier
choices.
The stability of the amplifier to be used should be con-
sidered, as it will affect the current capability and therefore,
the dynamics and realism of the music. A stable transistor
amplifier will be able to deliver twice the wattage into 4
ohm load as is does into an 8 ohm load. Amplifiers with
this ability should perform well with the Model Treo.

OMPONENTS
To maximize the performance of your system, you
should properly set-up your components according to the
manufacture’s instructions. Each component should be
placed on a piece of furniture or in a stand that is stable and
not prone to vibration or rocking. An isolation base or iso-
lation feet will improve the sound of some electronics.
Allow sufficient air space around the electronics for
needed air circulation. Excessive heat can both shorten the
the life of electrical components and impair their perform-
ance.
Preamplifiers and CD players should be left on all the
time. Amplifiers should be turned off when the system is
not being used. Once broken in, modern amplifiers sound
good after only 20 minutes of warm-up. Leaving the ampli-
fier on all of the time exposes the speakers to possible dam-
age from power line anomalies or electrical component
failure while the system is unattended

ABLES
Our evaluations and tests have convinced us the inter-
connect and speaker cables should be considered an inte-
gral part of the music system. Each brand and model of
cable has its own sonic characteristic and contributes to the
overall presentation of the music as much as any active
component. The Model Treo easily passes the amount of
information required to hear these differences between ca-
bles.
The testing also confirmed the importance of keeping
speaker cables as short as possible. In repeated trials, short
runs of moderate to inexpensive speaker cable consistently
out performed long runs of the same cable as well as much
more expensive cable. If your speakers must be placed a
long distance from your electronics, we recommend that
the amplifier be placed between the speakers and long in-
terconnect cables be used between the amplifier and power
amplifier so that short speaker cables can still be used. Cur-
rently, long interconnect cables seem to compromise the
sound of a stereo system less than long speaker cables.
When you evaluate different interconnect or speaker
cables, remember that the dielectric in most quality cables
takes many hours to fully form. These cables will not reach
their full potential until they have been used for several
weeks.
