Vienna Acoustics Concert Grande owner manual Room Treatment, Maintenance

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!
