About the recommended enclosures
The performance of these recommended enclosures will vary from
vehicle to vehicle. It is more difficult to get a tight and well defined
bass in a SEDAN vehicle because of the tightness between trunk and
interior. In most cases the recommended enclusures on next page is
the best choice. The sealed box is to be preferred.
- The given enclosure volume is the inner volume.
- Volumes occupied by speaker have already been added to the given
enclosure volumes so don’t add any more volume.
Important notice!
Nordica 10 & Nordica 12 have a design with ”open
voice coil” for improved cooling of the voice coil. This
construction also give the best sound performance.
To prevent dirt from entering the voice coil gap, follow
these instructions:
- Keep the speaker in the plastic bag until it is time for
installing the speaker in the box.
- Clean the speaker box inside from dust and dirt
before mounting the speaker, use a vaccum cleaner.
Enclosure placing in vehicles
In
small vehicles
like VW Golf, Peugeot 206, 306 and similar the bass
box should be installed with speakers directed backwards. Alternatively
directed upwards. This way of mounting is valid for all types of vehicles
where the trunk is incorporated with the inner compartment.
In
sedan vehicles
with the passenger compartment separated from
the trunk, the enclosure should be installed with speakers directed
towards the rear seat. Some cars have an opening in the middle of the
rear seat for loading skis etc. You can install the enclosure behind this
opening and direct speaker through this opening.
In
large vehicles
like station wagons the best sound is achieved with
the enclosure installed behind the rear seat with speakers directed
backwards. Alternatively you can install the enclosure on one side of
the luggage compartment.
Calculate your own enclosure
Box volumes:
When calculating the inner volume of an enclosure you just multiply the
width (W) x height (H) x depth (D).
Use measures in dm and you will get the answer in litres.
A trapezoid box is calculated as this:
Vol=width (W) x height (H) x upper depth (UD) + lower depth (LD)

Be sure to measure the
inside dimensions.
