Amplifier’s Choice
94dB effective sensitivity allows the use of low power amplifiers from 7Watt and
strong electrical and mechanical design allow the use of high power amplifiers up to
250Watt; of course quality is mandatory as this loudspeaker will cruelly show any
deficiency of the components of your system, not only the amplifier, but the source
and cables too.
Positioning your ALSYVOX speakers
Positioning in your room requires some move and listen trial, as always, but the line
source dipole dispersion will help with minimal room influence on the timbre of the
sound.
All sound radiating from the speaker, both directly towards the listener and in any
direction to be heard as reflected sound of the room are of the same quality and
tonally neutral; so any room will sound quite well. Of course better rooms will sound
better and each room will have its best speaker/listener positioning.
Just to start we advise you to position the speakers as symmetrically as possible
relatively to the room layout and the listening position with tweeters inside (binding
posts outside).
The speakers should be parallel to the rear wall and only later on toed in to be to find
the ideal tonal balance and image.
The front wall (behind the speakers) should be between 0.9m (3 feet) and 2.1m (7
feet) away.
The best result is most of the times achieved with a distance equal
to 30-40% of the total length of the room.
Of course what is behind the speaker will highly influence the sound, so avoid any
highly absorptive (open door) or highly reflective (window pane) surface.
On the other hand the sound radiated on the plane of the speakers is almost null, so
no big influence from reflections of side walls and they can be quite close (not less
than 0.15m, 1/2 foot).
The distance between the speakers is not very important, but it should be more than
1.5m (5 feet) and about 0.3m (1 foot) less than the distance from the listener.
The wall behind the listener should be quite absorptive and at least 0.9m (3 feet)
away
Trials can be made moving the speakers by 5cm (2”) each time and slightly changing
the toe in by 1cm (1/2”) each time.
In general the best toe in is between 20cm (8”) and 25cm (10”).
