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 spea-
ker 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.

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 volume.
- Use conical bass ports for best result. (DLS BP75 for
Iridium 10i & 12i, BP110 for Iridium 15). Cut the tube to
the correct length.
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 on 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.

Damping : Acoustic wool
F3 : 40 Hz
Outside box dimensions:
Width : 529 mm (20,83”)
Height : 320 mm (12,60”)
Lower depth : 247 mm (9,72”)

* Use the BP 75 port kit . Mount the flanges
on the tube ends. The port should be on the
side of the enclosure.
Cut the tube to it’s correct length.
