1. With the solder provided by Vandersteen Audio with the
replacement pair of matched drivers, solder the wires to
the driver terminals in the proper polarity. (Apply the
heat to the wire. When the solder flows to the terminal,
quickly pull the soldering pencil away.
This will avoid heat damage to the driver terminal’s
plastic parts.)
2. Install the driver into the cabinet with its screws.
3. Reinstall the grille structure.

Problem:
Subwoofer driver hums. Audible at the
listening position.
Solution: Try different grounding methods. Try floating the
main amplifier’s power cord with a cheater.
Never float the ground on the Model Seven power
cord. Attach a ground wire from the ground termi-
nal (near IEC connector) to the preamp.
Problem:
Still hums, grounding changes didn’t help.
Solution: Check your interconnect cables. Route cables
away from the amplifier. Position the M5-HP
crossover away from the amplifier. Verify
that the M5-HP is properly installed in the
system. Try the system at a very low volume
level without the M5-HP. If the M5-HP is the
source of the hum, it will have to be replaced
before the system can be used.
Problem:
Still hums, cable and crossover changes
didn’t help.
Solution: Disconnect the inputs from the Model Seven,
if the hum is still evident at the listening position,
please contact Vandersteen Audio.
(It is normal for the amplifier’s high-voltage
power supply to have a slight hum but
this should not be audible more than a few feet
away from the speaker.)
Problem:
No subwoofer output.
Solution: Verify that the Model Seven subwoofer ampli-
fier is plugged into a live AC outlet. (It should
thump or pop when you plug it in.) Verify
that the AC cord is securely inserted into the
Model Seven’s amplifier.
Problem:
High or low subwoofer output level.
Solution: Verify the actual input impedance of the main
amplifier and that the M5-HP is correctly
matched to it. Check the low-frequency level
and contour control settings.
Problem:
Model Seven amplifier excessively hot.
Solution: Remove the amplifier according to the instruc-
tions on page 16 and return it to Vandersteen
Audio for service.
Problem:
Unsatisfactory high-frequency balance.
Solution: Check the high-frequency level and contour
control settings.

Q
UESTIONS
Can a subwoofer or subwoofers be added to a system
with Model Sevens?
The Model Sevens contain integral subwoofers and
there would be no benefit or advantage to adding separate
subwoofers. When the Model Sevens are used in a home
theater system, program the processor to redirect the Low
Frequency Effects (LFE) and subwoofer information to the
front channels where it will be reproduced by the Model
Seven subwoofers. Some may want to add an LFE sub.
What speaker cables sound best with the Model Seven?
The cables that sound best with your Model Sevens are
the cables that are most complementary to your particular
associated equipment, the characteristics of your room
and your personal taste. There is no way for us to ade-
quately evaluate two of the three deciding factors, (room
and taste) so there is no way for us to accurately predict
what cables will sound best with your Model Sevens.
How will I know when an update is available for my
Model Sevens?
Vandersteen dealers will be notified when Model
Seven updates are available. In most cases, the update
will be performed by the factory. Some updates may be
available to the original owners only. The only way to
prove this is by registering the warranty or keeping the
original invoice.
