EQUIREMENTS
The Model Seven is designed for use with amplifiers
rated from 30 to 200 watts per channel into 8 ohms. These
amplifiers will provide ample power for realistic listening
levels in most situations. Amplifiers with less than 75
watts should be tested with the volume control half the
way up (the point where most amplifiers clip) to verify
that the system can achieve realistic listening levels with-
out stress. Amplifiers with more than 200 watts must be
used with caution due to the increased potential for
speaker damage if they are misused or an accident occurs.
The Model Sevens are very revealing speakers and
are easily capable of showing the subtle sonic differ-
ences between amplifiers. They will perform well with
a tube, transistor, or hybrid amplifier, allowing each
design to realize its full potential.
Fuses between the amplifier and the Model Seven
will degrade the performance of the entire system. No
fuses are used in the Model Seven and preference
should be given to the use of an amplifier that does not
use output fuses.
Preamplifiers and CD players should be left on except during electrical storms or ex-
tended absences. Amplifiers should be turned off when the system is not being used.
Once broken in, modern power amplifiers sound good after only 20 minutes of
warm-up. Leaving the amplifier on all the time exposes the speakers to possible dam-
age from power line anomalies or electrical component failure while the system is un-
attended.

LEANING
The appearance and performance of the Model Seven
can be enhanced by observing a few precautions and per-
forming some simple maintenance.
The input terminals on the Model Seven and the spade
lugs on the speaker wire should be cleaned periodically
with alcohol or a solution made specifically for cleaning
electrical contacts. Other connection points in the system
should be cleaned as per the equipment manufacturer’s
recommendations.
The grille cloth on the Model Seven can be gently
vacuumed using a brush attachment that will not snag the
cloth. The automotive finish should by cleaned with a
damp soft cotton cloth (old T shirt). The polyurethane
clear coat can be maintained with an occasional coat of
car wax, being careful not to get it on the grille fabric.
Do not use Windex or any product with ammonia on the
Model Seven.
The speakers should not be exposed to excessive heat
or direct sunlight which can damage the fit and finish of
the fine finish.

ERVICE
In the unlikely event that your Model Sevens require
service, please follow these procedures.
1. Verify that your Model Sevens have been set-up and
connected according to the instructions in this manual.
2. Verify that the problem you are hearing is in the
speaker by switching the left and right speaker cables
at the speakers. If the problem switches sides, it is in a
component or cable rather than the speaker.
3. Play each bass input and the midrange/treble input of
the suspect speaker separately to determine which sec-
tion has a problem.
4. Contact Vandersteen Audio with your Model Sevens
serial number, information on your associated compo-
nents, a description of the problem and the steps you
have taken to isolate it to the Model Seven.
5. The Model Seven is a modular system. Should
Vandersteen Audio determine that a module needs to
be returned to the factory for repair, a Return Au-
thorization form is available on our website.
(Due to the precise driver matching, drivers may
need to be replaced in pairs).
6. Return the damaged or defective module and the
completed Return Authorization Form to Vander-
steen Audio. Any shipment of a complete Model
Seven to the Factory will be refused.
