Running-in time
Allow the subwoofer to play for at least
15-20 hours in order to perform at its
possibly best. This run-in can be made with
bass tone sweep or with just music. Start at
a moderate volume and increase the
volume step by step during the running-in
period. After the 15-20 hour run in session
the performance and characteristics will be
in the correct condition.
Enclosure info
This subwoofer is normally designed for
enclosure mounting. In ”open air” installa-
tions the power handling capacity is
reduced by more than 30% from the
nominal value.
DLS support
For technical assistance, ask your car
audio dealer where the product was sold or
the distributor in your country. You can
always contact the DLS Helpdesk in
Sweden at this e-mail: [e-mail].
Information can also be found on our
WEB-site www.dls.se We follow a policy of
continuous advancement in development.
For this reason, all or part of specifications
and designs may be changed without prior
notice.
Build your enclosure in a stable and airtight
material. MDF-board or particle board,
19-25mm is two good choices. Larger
enclosures must have bracing inside to
avoid vibrations. The enclosure must be
completely airtight. Use sealing compound
in all joints, also around the cable
terminals. The size of the enclosure is
decided and calculated by the
electro-acoustic parameters of the woofer.
DLS recommends that you should choose
the enclosure you will use based on the
type of music you listen to, how much
amplifier power you will use for the
subwoofer and how much space inside the
vehicle you can devote to a subwoofer
enclosure.
Note! RCW12.D2 has a design with “open
voice coil” for improved cooling. This
construction gives the best sound perfor-
mance. To prevent dirt from entering the
voice coil gap, follow these instructions:
• Keep the subwoofer in the plastic bag
until it is time for installation.
• Carefully clean the enclosure inside with
a vacuum cleaner before mounting the
subwoofer.

We do not recommend using an ”open air”
