Enclosure Placement; Calculate Enclosure Volume - DLS PERFORMANCE PS10 User Manual

Note! The performance of the recommen-
ded 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 separated space between
the trunk and the passenger compartment.

Enclosure placement

In smaller vehicles of different models (like
a VW Golf, Peugeot 206, 306, etc. the
enclosure should be installed with the
subwoofer directed backwards or 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 where the passenger

Calculate enclosure volume

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.

compartment is separated from the trunk,
one option is to install enclosure with the
subwoofer directed towards the rear seat.
Some cars have an opening in the middle
of the rear seat for storage. You can install
the enclosure behind this opening and
direct speaker through this opening. Be
sure you seal the sides of the enclosure
with additional covering so no pressure will
slip between the opening and your
subwoofer and into the trunk area. The
floor and sides in the trunk area can also
be good alternatives for the enclosure
placement.
In large vehicles like station wagons the
best sound is achieved with the enclosure
installed behind the rear seat with subwoo-
fer directed backwards. Alternatively you
can install the enclosure on one side of the
luggage compartment.

Vol = Width(W) x Height (H) x (Upper depth(UD) + Lower depth(LD))
