incredibly transparent reproduction because all drivers

from 100Hz and above are made of the same material

with exactly the same char-

acteristics. These very stiff

diaphragms allow for dy-

namic contrast unheard of

with typical materials. On

the rear input plate are

eleven room compensation

controls that a qualified tech-

nician uses to match the low

frequencies to the listening

room, and level and contour

controls that allow you to

tailor your Model Sevens to your own personal taste.

The Vandersteen Model Seven is designed and built in

the United States of America.

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.

Vandersteen Audio

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.)
