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.

Safety Notes

Installation and installation instructions

Disconnect the negative terminal

of the battery before carrying out

installation and connection

work.

Observe the vehicle manufactur-

er’s safety instructions (regarding

airbags, alarm systems, trip com-

puters, vehicle immobilisers).

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

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.

Recycling and disposal

To dispose of the product, please use the avail-

able waste return and collection systems.
