Для предотвращения вибрации в корпусах больших раз-
меров целесообразно устраивать ребра жесткости.
При заполнении внутреннего пространства акусти-
ческим изолирующим материалом (овечья шерсть
или полиэстеровая вата) минимум на 50 процентов
эффективный объем корпуса увеличивается от 5 до
15 процентов.
Кабели от усилителя к сабвуферу должны быть как мож-
но короче и иметь минимальное сечение в 2,5 мм
Готовый корпус сабвуфера должен быть абсолютно
стабильным и герметичным.
При возможности установить басовый рефлексный
туннель диаметром от 7 до 10 см, чтобы предотвратить
возникновение обычных для малых отверстий шумов
от движения воздуха. В торговле можно найти трубы
ПВХ различного диаметра, причем части трубы мож-
но прокладывать в корпусе с помощью шарнирных
элементов.
Использовать активные (электронные) частотные
разделительные фильтры, такие, как например, уста-
новлены во всех усилителях Blaupunkt. Использовать
пассивные частотные разделительные фильтры не
рекомендуется.

and
connection
Prior to drilling the mounting holes, make sure that no
cables and parts of the vehicle will be damaged.
Do not install subwoofers on loose rear shelves (fastback
vehicles) or at places open to the front.
Leave ample clearance between the cables and other
harnesses. Use the enclosed cable ducts at sharp-
edged holes.
Notes about installing subwoofer housings
Before installing the housing, please observe some
fundamental design instructions:
Subwoofers with infi nite baffl e can be installed in a ve-
hicle by simply using a wooden board trimmed to size
which ensures an acoustic separation between the front
and rear sound components of a woofer. The wooden
board is affi xed in the trunk under the rear shelf or in
the back of the rear seat bench. Any existing air gaps
should be sealed with sealing material.
The shape of the housing plays only a minor role with
respect to the playback of low frequencies and, there-
fore, is rather freely selectable. However, try to avoid
unusual shapes which require extensive work with re-
spect to trimming and gluing.
MDF boards or high-quality plywood made out of birch
with a thickness of 18 to 25 mm are perfectly suited
for building speakers.
All abutting housing walls should be glued, screwed
together and sealed to avoid a continuing detachment
due to vibrations and environmental infl uences in the
vehicle.
To avoid vibrations, stiffening ribs are useful for large
speakers.
Acoustic insulating material (sheep's wool or poly-
ester web) which fills the inside volume to at least
50 percent increases the effective housing volume by
5 to 15 percent.
The cables from the amplifi er to the subwoofer should
be kept as short as possible and have a cross-section
of at least 2.5 mm
2
.
The fi nished subwoofer housing should be perfectly
stable and airtight.
If possible, use bass refl ex channels with a diameter of
7 to 10 cm to avoid the air noises generally associated
with smaller openings. PVC pipes are available commer-
cially in different diameters, whereby the pipe sections
can be routed inside the housing using appropriate
joints and fi ttings.
Use active (electronic) crossovers, such as those inte-
grated into all Blaupunkt amplifi ers. The use of passive
crossovers is not recommended.

able waste return and collection systems.
