Thank you for choosing the Vandersteen Model Seven Reference Loudspeaker System. While the
grilles are removable, we recommend that you leave them on the speakers at all times. The Model
Sevens were engineered and measured with their grilles in place. Removing the grilles compro-
mises the performance of the speakers and exposes the drivers to possible damage from probing
fingers. For a complete understanding of the Model Seven's innovative technology and unique fea-
tures we recommend that you review this entire manual before connecting or using your new
speakers.
The Model Seven combines the superior openness and
realism of the legendary Vandersteen boxless design with the
powerful, extended bass of an
amplified subwoofer in a com-
pact and elegant loudspeaker.
Unique features optimize the
Model Seven for a wide vari-
ety of placements, environ-
ments, and system configura-
tions. It is available in any
automotive finish to comple-
ment any décor.
The Model Seven incorpo-
rates advanced patented Car-
bon Fiber/Balsa sandwich cones and domes for the midbass,
midrange and tweeter. This technology allows true piston
operation for each driver in its pass-band, allowing very low
distortion and uniformity in sound. This innovation offers
Unless the high-pass crossover is built into the electronics, (See page 3.) the Model
Seven system requires a M5-HP crossover between the preamplifier and main power
amplifier that is matched to the input impedance of the power amplifier. Using the
speakers without a properly configured M5-HP in place will severely damage the
midbass drivers. The drivers in your Model Sevens are critically paired to within one
tenth of a dB. In most cases if one driver is damaged, the pair must be replaced.
Physical damage (probing fingers) or damage due to a missing or improperly config-
ured M5-HP crossover will require non-warranty replacement of two very expensive
drivers. (Minimum $480.00 per pair for the tweeters alone.)
