er, we suggest you use 12 AWG or larger wire. For specialty wire considerations, consult your local Authorized NHT Dealer.
Prepare your speaker wire by stripping 1/4” to 3/8” of insulation from the ends and twisting the exposed wire strands tightly. The
five-way binding posts on the back of the SW3S will accept raw wire, banana plugs or spade plugs. Tighten the binding posts by
hand, as pliers can strip or break them.
Be sure to wire the subwoofer “in phase”. That is, the positive (red)
terminal on the amplifier output must be connected to the corre-
sponding positive (red) terminal on the subwoofer. Likewise with the
negative (black) terminals.
All speaker wires have some sort of marking along one or both conductors
to help you make the correct connections.
To minimize noise pickup, segregate cables by function. Do not run low
level signal cables parallel to power cables, speaker cables, or digital
cables. Also, do not run speaker cables or digital cables parallel to power
cords or parallel to each other. If different types of cables are placed near
each other at some place in your system, separate them by the maximum
practical distance and cross them at right angles where they meet.
When using two SW3S subwoofers with a single SA-3 subwoofer amplifier,
the two subwoofers are wired in parallel. Using two equal lengths of speak-
er wire, connect the positive (red) conductors of both wires to the positive
(red) terminal on the amplifier, and both negative (black) conductors to the
negative (black) terminal on the amplifier. Then, connect one speaker wire
to the first subwoofer (positive conductor to positive terminal, negative
conductor to the negative terminal), and other speaker wire to the second
subwoofer, wired in the same fashion (Fig.1).
Operation
The SW3S subwoofer was designed to handle a wide range of listening levels, but every speaker has limits. It is important to use
common sense and listen for signs of possible distress from the speaker. Noticeable distortion or harsh breakup is an indication
that either your amplifier or your speakers are running beyond their capacity, and the volume should be decreased. If you can feel
any heat emanating from the front of the woofer, reduce the level immediately. Speaker damage most often occurs from sustained
high volume levels, not from transient sounds or brief musical peaks. Excessive boosting of bass or equalizer controls can
worsen the problem, and is not recommended.
Maintenance
Your subwoofer requires minimal maintenance under normal use. The cabinet may be cleaned using a damp cloth or a mild, non-
abrasive glass cleaner. To clean the grille, first remove it from the subwoofer, then brush lightly with a soft brush or use a
vacuum on its lowest setting. Do not expose the subwoofer to direct sunlight, high temperatures, or moisture. Do not attempt to
clean the actual driver.
