About this Device
Ambience 31 Operating Manual 5
A T D
The Burmester Ambience 31 loudspeaker owes its lean elegance but elemental bass
power to the partitioning of its diaphragm surface into one woofer and one woofer/
mid-range driver per speaker. A bass reflex port provides support in the lowest range.
A new Air Motion Transformer (AMT) was custom-developed for the high range. For
many years, the Burmester AMTs have been regarded as a benchmark for ultimate
precision, neutrality, power handling, and dynamics in the high frequency range.
The Burmester Ambience 31 loudspeaker owes its spacious sound talents to a second,
back-firing AMT on the rear of the cabinet, which optimizes the omnidirectional
behavior and makes the listening room an even more integral part of the sound
experience. With continuous level adjustment, the Burmester Ambience 31 can be
optimally adjusted to the individual space and your sound preferences.
Highlights:
• Custom-developed Air Motion Transformer (AMT)
• Second AMT tweeter (Ambience tweeter), back-firing and continuously adjustable
• 2 ½-way system

4.3 Set-up
Carefully remove the speakers from the transportation packaging and place them in a
suitable location. Avoid direct sunlight, dust, and moisture.
4.3.1 Correct positioning
The speakers can be easily integrated in virtually any interior. Optimal acoustics can be
achieved by positioning your speakers so that they create an equilateral triangle, with
the third point being the listener (as seen from above).
The spatial audio reproduction increases with a greater distance between the speakers
and the wall, while the bass reproduction decreases. The BA31 speakers are designed
so that they do not need to be positioned near a wall to accentuate the bass. However,
since listening spaces have very different acoustic properties, positioning near a wall
may improve the acoustics in some cases.
The two speakers should be placed 2.50m to 4.00m apart. Ideally, the space between
them should remain free of any other objects. In a room with a rectangular floor space,
it is preferable to place the speakers on the longer wall instead of the shorter wall.
Similarly, positioning in the “hard” acoustic area (along smooth walls and windows) of
the room is preferable to the “soft” acoustic area (muted by upholstered furniture,
books and carpet). This especially applies for the ambience tweeter (see „Improving
your audio — ambience tweeter“ on page18).
note If you have a television set with a cathode ray tube, maintain a minimum distance of
50cm between the speakers and the TV set. Otherwise, the magnetic fields of the
speakers can cause isolated color changes in your TV image.
