CONCERT GRAND SERIES
OWNER´S MANUAL
Now, as always, speakers form the most important link in a stereo system. Therefore,
they should be positioned and connected with care. It is our hope that the information
contained within this manual will help you in setting up your new speakers and
provide you with many years of listening pleasure.

CABINETS
Our speaker designs feature massive and inert cabinet construction. Vienna Acoustics
cabinets are designed with the latest computer modelling techniques and use a
combination of amorphous materials in order to ensure that they are both stiff and
well damped. Additionally, our designs feature massive, but narrow/slim, front baffles
in order to promote accurate imaging. The combination of precise build construction
using furniture grade finishing techniques and complex internal damping produce
designs capable of accurately rendering music.
All speakers are equipped with spikes, and in some cases bases. Please use them and
care for maximum stability by adjusting the spikes. To protect your wooden floor all
base/spike sets include spike-plates.
BURNING OR BREAKING IN NEW
LOUDSPEAKERS
Your loudspeakers contain a large number of precision built moving parts. These parts
require playing time initially to develop their maximum smoothness and extension.
Very audible improvements can be observed during about 30 hours of playing.
Additional improvements will be evident after 100 hours of playing time, at which
point the speakers have reached their full musical potential.
POSITIONING
Room acoustics and positioning of the speakers within the room have an important
effect on sound quality. To find the optimal position for your speakers we offer the
following hints:
FREE AIR SET-UP
If the room is large and space permits, allow a minimum of 1 meter away from the
rear wall (behind the speakers). Small movements of the speaker forwards and
backwards will establish where a speaker sits most comfortably. Find the location that
gives a full balance without sounding heavy.
Remember, in free air set-up the distance from the rear wall determines how low the
speaker will go in a room and also the depth of image. Positioning too close to a rear
wall may boost the middle bass frequencies
and rob the speaker of some
transparency and precision. In general it is best to avoid corner placement of speakers
since the bass tends to become exaggerated and corners rarely are an optimal
placement for image quality.
NEAR WALL POSITIONING
Many people will simply find it undesirable or disruptive to place speakers in "free
space", that is well away from the back wall. Vienna Acoustics loudspeakers may be
set-up close to a rear wall, though keep in mind that less toe-in, as described below,
will probably be needed. When working close to a rear wall, even the tiniest
movements will have a relatively important effect on sound quality. Work slowly and
methodically, following the instructions below and good sound quality can be achieved.
DISTANCE BETWEEN THE
SPEAKERS AND TOE-IN
Most stereo systems are set-up with their speakers too close together. As a rough
guideline, the distance between spea-kers should be about 70 % of the room width as
a starting point, assuming that your speakers are aiming down the length of the room.
Too close together they will create "ghost" images, double images that blur clarity and
focus. Too far apart they will begin sounding thin and in extreme cases, will create
separate left and right soundstages. Move them inwards and outwards, again in small
movements as though you were adjusting the image on a pair of binoculars until a
single well-unified image is obtained.
Toe-In: In an ideal room, the speakers may be set-up so that the speakers fire directly
forward. For the rest of us, some degree of toe-in, that is rotating the speakers
cabinets until they point at the listener is desirable. Toe-in reduces sidewall reflections
of the mid and upper frequencies. Though one might reasonably conclude that aiming
a speaker at the listener would result in a brighter sound, this is mostly not the case.
Toeing a speaker inward will result in a smoother, warmer and usually more focused
sound.
Important Tip:
The distance between speakers is interrelated to the degree of toe-in. If a speaker
loses clarity from toeing in, try increasing the distance between them slightly. This will
have the effect of "opening up" the speaker and restoring clarity.
ROOM TREATMENT
Good sounding rooms have a well-balanced acoustic. This does not mean that your
home should look like a recording studio. Commonly found furnishing such as
bookshelves, carpeting and furniture all exhibit beneficial amount of ab-sorption and
dispersion. Rooms with little furniture, carpeting or other surfaces will demonstrate
poor damping and will produce a hard, bright sound.
As a general rule, it is helpful to have more of these sorts of things in the space
immediately around the speakers than scattered throughout the space. A thick carpet
or area rug mounted between your listening position and the speakers is of
tremendous benefit in controlling reflections off the floor. Tapestries, hanging rugs
and/or drapes on the side walls hung slightly ahead of the speaker position will damp
reflections off these surfaces.
MAINTENANCE
Your speaker cabinets can be cleaned periodically with a soft, slightly damp cloth. It is
not necessary to wax them. Our cabinets feature a smooth but strong finish. Still,
please keep them out of direct sunlight and out of heat, since the colour of the veneer
would pale. Should the bass drivers become dusty, it is safe to use a soft brush to
clean the woofers.
* Under NO circumstances should you attempt to clean dust from the tweeter. Doing
so will damage the delicate silk domes.
! Additional Instructions for MOZART Grand !
Please take note of an important feature of Mozart: We have added 2 pieces of BCUs
which can be used to close one or both reflex-ports on the rearside of the speaker.
This is an important room tuning aid: As Mozart has unparalleled low bass capabilities
compared to its size, some rooms can create problems with such low frequencies. By
closing the reflex-ports low frequencies are reduced in amplitude and thereby
matching bass-boosting rooms.
As always please start with careful positioning of the speaker. This will enable true
high end bass in such a superior depth and quality only being known of bigger and
much more expensive speakers. Various positions will make it possible to compensate
the many bass-modes each room has, and these bass-modes are crossing the room
quite close to each other that´s why positioning works. Some rooms however are very
difficult to handle (or your preferred position is pre-determined), in these cases the
BCUs are wonderful room tuning devices.
Happy Listening!
