X-PROGRAM X-WB08, X-WB10, X-WB12 Owner's Manual

X-PROGRAM

Subwoofers

Owners manual

Thank you for buying an X-program subwoofer.

Please read this manual before installation.

Installation

The subwoofer must be installed correctly in order to work well.
This manual will show you how to install it like a pro. Please read
the entire manual before beginning the installation.
Install the subwoofer yourself if you feel confident with our
instructions and if you have the proper tools. However if you feel
unsure, turn over the installation job to someone better suited to it.

Connection

How to connect depends on what type of amplifier you use. The
best is to follow the instructions given in the manual for the
amplifier. Most amplifiers today have built-in lowpass crossover
and possibilities to connect your subwoofer in bridge mode.

Please note that the X-WB10 and X-WB12 subwoofers have a 2
ohm voice coil, if connected in bridge mode to your amplifier the
resulting impedance is 1 ohm. This means that your amplifier
must be 1 ohm stable.
Make sure to connect in a way that don´t ruin the amplifier. If you
have an X-A10 mono amplifier it´s possible to connect two
subwoofers in parallel, this amplier is 1 ohm stable.

We also recommend the use of a subsonic highpass filter. This
gives a better bass reproduction with less "rumble". In all X-pro­gram amplifiers this feature is already built-in.
For wiring use high class speaker wires, min AWG13 (2.5 mm

2

).

For models:

X-WB08 - 8”
X-WB10 - 10”
X-WB12 - 12”

Running-in period

Allow the speakers to play for at least 15-20 hours. After this
time the performance is correct.

Subwoofer enclosures

Build your enclosure in a stable and airtight material. The best is
MDF-board, 19 mm, or particle board, 22 mm. 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
by the speaker data. The parameters of the X-program 8” and
10” subwoofers are suitable for both sealed and vented

enclosures, for the 12” we recommend only sealed enclosure.
On next page you find our recommended enclosures.

Sealed enclosures

Sealed enclosures are easy to build. The speaker data such as
Fs, Qts, Vas and X-max decides the size of the enclosure.
Large speakers need larger boxes. Two speakers need a box of
the double size etc. The enclosure must be completely airtight.
A sealed enclosure should be filled with acoustic wool up to 75 ­100%. We advice you to follow our enclosure recommendations
on next page.
A sealed enclosure has a lower efficiency than vented enclosures
but can handle high power and is easy to build. A subwoofer in
a sealed enclosure creates a tight bass suitable for the
audiophiles listening to classical music, jazz and soft rock.

Vented enclosures

A speaker in a vented enclosure has a higher efficiency (+3 dB)
and higher power handling capacity than in a sealed enclosure.
In a vented enclosure the sound from the speaker and the port
work together creating a higher sound level. The sound from the
port must come out in the same phase as from the speaker cone,
otherwise the result is bad.
The size of the vented enclosure is decided by the speaker data
just as for the sealed one.
We advice you to follow our enclosure recommendations on next
page.

Important!

Think of the speaker weight when you do your install. Use heavy
bolts when fastening the sub to the enclosure baffle.

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:

Volume = width (W) x height (H) x upper depth (UD) + lower depth (LD)

Be sure to measure the
inside dimensions.
