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 below is the best choise. The
vented box is to be preferred.
- The given enclosure volume is the inner volume.
- Volumes occupied by speaker and ports have already been added to
the given enclosure volumes so don’t add any more volume.
- Use DLS bass port kits for best result.
There are two flanges coming with this kit. The larger one is for the
outside, and the smaller one should be attached to the tube inside the
enclosure.
Make a round hole in the box where you want to mount the bass port.
The larger flange should beattached to the outside of the box. Fasten
it to the box with screws or with some glue. There are prepared drill
holes on the back of the flange.
The smaller flange is for the inner end of the tube. Use a PVC-glue to
attach it to the tube.
Then glue the tube to the port mounted in the box.
Use sealing compound round the flange to make the box as airtight as
possible.
ENCLOSURE PLACING IN DIFFERENT TYPES OF
VEHICLES
In
small vehicles
like VW Golf, Peugeot 306 and similar the bass box
should be installed with both speaker and port directed backwards.
Alternatively booth speaker and port can be 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 booth speaker and port
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 or port through this opening. There
must be some free space in front of the port, (between the rear seat and
the port opening).
In
large vehicles
like station wagons the best sound is achieved with
the enclosure installed behind the rear seat with booth speaker and port
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 liters.
A trapezoid box is calulated as this:
Vol=width (W) x height (H) x upper depth (UD) + lower depth (LD)

Be sure to measure the
inside dimensions.
