fine tuning
To fine tune the position of your F1 AvantGarde loudspeakers,
choose some music material you are familiar with and sit in the
central listening position. Pay attention to the tonal balance of
the reproduction and the accuracy of the stereo sound-stage.
Moving the loudspeakers away from the rear wall and into the
room will reduce the amount of low frequency energy with
respect to the rest of the audible bandwidth. Conversely, moving
the loudspeakers closer to the rear wall will increase the low
frequency energy. The distance between the loudspeakers and
the amount of toe-in will affect the stereo sound-stage. With
careful and patient experimentation, you will find a configuration
that will provide an even and neutral tonal balance with an
accurate sound-stage. Don’t be afraid to experiment.
Once you have found the ideal position of your F1 AvantGarde
loudspeakers within your listening room, you may add the spikes
to fix the loudspeakers physically with respect to your room.
Carefully rock the loudspeaker enclosure to one side and insert
the spikes one at a time ensuring that the lock nuts have been
fastened onto the thread of the spike prior to insertion into the
base of the loudspeaker. Gently lower the loudspeaker back onto
the floor and repeat the process for the other two spikes.

You will get the best sound from your F1 AvantGarde loudspeaker
if you follow these guidelines:
Try to place each loudspeaker approximately 0.5 m (2 feet) from
all walls. Space them between 2 and 3 meters (6 - 10 feet) apart.
Try to locate both loudspeakers in a similar accoustic
environment. Toe the speakers in so that the axis of the
loudspeakers points just outside the listening zone (see page 15).
Your F1 AvantGarde loudspeakers arrive factory fitted with the
mean low frequency tuning mass cap fitted to the lower bass
drive unit. You can tune the low frequency energy output to your
room conditions and subjective preference by removing and/or
replacing this mass cap for another graduated mass cap that you
will find in your accessory pack.
The installation of a heavier mass cap will reduce the low
frequency output and conversely, installing a lighter mass cap
will increase the low frequency output. You may choose not to
fit any of the optional mass caps to maximise the low frequency
output but always remember to fit the retainer plug to ensure
that the only air passage through the lower bass system is
conducted via the downward firing reflex port as intended.
