THE ULTIMATUM XLS LOUDSPEAKER
INSTRUCTIONS FOR USE
Congratulations on choosing the ULTIMATUM XLS loudspeakers. Please read the following notes in order to get
the best from them.
RUNNING IN
A 'running in' period of at least 200 hours is necessary for optimum performance.
SETUP
The XLS should be used on rigid stands and fixed with blu-tack or similar adhesive putty.
Caution: The XLS loudspeaker should be removed from the stand when being moved.
PLACEMENT IN THE ROOM
Room acoustics vary tremendously and there are few hard and fast rules about placement. A degree of
experimentation is necessary for optimum placement but a
starting point
of 30 cm from rear walls and 60 cm
from side walls is suggested, with a toe-in of 10-20 degrees. Generally, bass output increases as distance from
the rear wall, or room corner, decreases. Stereo depth and associated effects improve as the speaker is brought
away from room boundaries.
Perseverance at the setup stage will be rewarded. Move the loudspeaker in small increments (2-3 cm) and
assess the changes until satisfied with the in-room balance.
Often, very small changes of the loudspeaker
position can result in a substantial improvement in performance.
CONNECTIONS
The ULTIMATUM XLS is supplied with bi-wiring/bi-amplification terminals, which are fitted with links in order to
facilitate single wiring.
Bi-wiring is effected by running two sets of cable from the amplifier output terminals. Connect one set to the
lower and one set to the upper terminals on the rear of the speaker. Take care to ensure correct phasing (i.e. red
and black connections maintained at amplifier and speaker). Bi-wiring can bring about a significant change in
performance and this should be evaluated on an individual basis. Some amplifiers will respond better than
others, whilst personal taste is also a strong factor.
Bi-amplification is highly recommended. This involves the use of 2 stereo amplifiers (or 4 mono amplifiers).
When this mode of operation is being considered, it is advisable to consult a dealer, or Neat Acoustics, for
advice.
