Rotate the dust cap by about 15° in an
anti-clockwise direction, at this point the
dust cap is no longer locked into position
and is ready to be lifted out with an
upward movement.

There is a triangle on the dust cap which
is lined up with a vertical plastic indicator
when the dust cap is locked into position.

When the dust cap is rotated as described above,
the triangle is no longer aligned with the plastic
indicator and the dust cap is ready for removal.

To re-insert the dust cap, reverse this procedure
until the triangle is aligned with the plastic
indicator.

Use the “input” tags for
connection to the speaker.
The speaker can be
connected directly to an
amplifier without the use of a
crossover.

Use the “input” tags to connect the speaker.
It is possible to connect the speaker directly
to an amplifeir without the use of a
crossover.

For the tweeter connection use the “output”
tags. The three tags allow the use of the
tweeter options.

The tweeter offers four options:
FLAT, in phase / FLAT, Out of phase / ATT, in phase / ATT,
out of phase.
These four options can be used in both the Combinable and
Separate modes.
We suggest using the FLAT in phase when first installing the
speakers. Insert the tweeter in the support following the,
indications of the negative (-) on the side of the tweeter
(indicated with on the drawing).

For an angled installation,
choose the desired location and
drill the necessary holes, screw
tweeter support “A” into position.
Place support “B” so that the screw
holes correspond with the tubes of
support “A” to allow fixing.
Insert the tweeter “C” in the support
following the instructions shown under
”Tweeter Options” .
For connection of the tweeter
to the built-in crossover, use
the extension lead supplied
and be sure to follow the colour
scheme for correct function.

In order to use the system in the combinable mode you should remove the
dust cap in the centre of the woofer. To do so apply slight pressure to the
edge close to the dust cap support.

Insert the tweeter in the support

pushing it down until it is hooked

into position.

Follow the indications on the

tweeter for the indentification of the

negative (-).

To select the desired tweeter

option, insert the tweeter in the

appropriate position following the

indications on the support.

The crossover filter is inside the

magnet cover and therefore the

use of external components is not

necessary. The built-in crossover filter will be activated when the

tweeter is inserted in the support.

The speaker system can be combined to act as a “Coaxial” with great performances and really useful options
such as phase rotation and attenuation of the tweeter without external intervation.

An incredibly flexible separate component system which allows installation and adjustment in a practical and
wonderfully simple manner thanks to the options on the tweeter support. You can adjust your system while sitting
in your listening position just by rotating the tweeter in its support to select the desired option.
