THE MOMENTUM SX3i LOUDSPEAKER
INSTRUCTIONS FOR USE
Congratulations on choosing the MOMENTUM SX3i 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 MOMENTUM SX3i should be used on rigid stands, 45 - 60cm tall, and fixed with blu-tack or similar
adhesive putty.
PLACEMENT IN THE ROOM
A degree of experimentation is necessary for optimum placement but a starting point of 20cm - 30cm from rear
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 improves as the speaker is brought away from room boundaries.
Perseverance at the setup stage will be rewarded. Move the loudspeaker in small increments (2 - 3cm at a time)
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 Momentum SX3i is supplied with a single pair of terminals as standard, to facilitate single (normal) wiring.
If you have ordered a dual pair of terminals you may bi-wire or bi-amp the Momentum SX3i.
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, and personal taste is 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.
