THE MOMENTUM SX5i LOUDSPEAKER

INSTRUCTIONS FOR USE

Congratulations on choosing the MOMENTUM SX5i loudspeakers. Used correctly, they will provide a lifetime of beautiful
music. Please read the following notes in order to get the best from them.

CAUTION! The woofer in the base of the cabinet can be easily damaged.

HANDLE WITH CARE.

RUNNING IN

A 'running in' period of at least 200 hours is necessary to stabilise performance. After this period, a further

gradual improvement will occur over a period of several weeks.

ASSEMBLY

The speakers are packed in two separate cartons.

Unpack, and place the speaker upside-down on a clean, non-abrasive surface. Fit the supplied end spikes to the cones
on the base of the speaker. Do not fit the end spikes if the optional slate plinths (see below) are to be used.

Return to upright, place the speaker in required position. Level the speaker by tilting the speaker and adjusting the
spikes. When the speaker is level and stable, the spikes are automatically locked in place.

OPTIONAL SLATE PLINTH

Dedicated solid slate plinths can purchased and fitted to the SX5i. Follow the instructions supplied with the plinths.

CONNECTIONS

The Momentum SX5i 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 SX5i.

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.

PLACEMENT IN THE ROOM

There are no firm rules regarding placement, as acoustics will vary from room to room. A degree of experimentation is
necessary for optimum placement but a starting point of 20-30cm from rear walls is suggested, with a toe-in of 10-15
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. Move the loudspeaker in small increments (2-3 cm 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 huge improvement in performance.)

MAINTENANCE

The MOMENTUM SX5i has no user-replaceable parts and requires no maintenance.
To clean, brush lightly with a soft, lint-free cloth. Should a fault condition arise, consult your dealer.
