In-wall installation

Fitting the ALF120 into the wall

Brush any dust out of the wall cavity.

Carefully lift the ALF120 into the wall

cavity.

If there are any problems with the fit
of the ALF120 in the cavity, now is the
time to resolve them.

Testing the ALF120

At this point the ALF120 should be fully 
tested.

CAUTION! The ALF120 must only be 
tested with a DSP equipped amplifier 
such as the Amina A100Q that can be 
programmed to include frequency 
correction for the ALF120.

Using a wideband amplifier with no 
equalisation may permanently damage 
the ALF120.

Connect the amplifier to the cable

from the ALF120.
Disconnect any other system

speakers.
Play a signal with high bass content.

Increase the volume level and listen

carefully for vibration or other noises.
If you hear any vibration or noises

locate the source of these and rectify
the problem.
Connect up the system in-wall or

free-standing speakers.
Test the complete system to confirm

that the sound from the subwoofer
integrates well with the other
speakers.

Check that the front of the cabinet

lays within the front line of the
adjacent wooden studs.

If the cabinet protrudes beyond the
studs, the wall-board will interfere with
the front of the cabinet when installed.
