Check Speaker and Parts
Unpack and carefully check each loudspeaker. If you suspect damage from transit, report
the problem immediately to your dealer and/or delivery service.
If possible, save the shipping cartons for future use. Please ship the foam packing material
to: Induction Dynamics, 10661 René, Lenexa KS 66215.
General Care of Your Loudspeaker and Amplifier
Whenever changing speaker wires, interconnect wires, or power cords, always turn off all
equipment. To prevent fire or shock hazard, do not expose the amplifier to rain or excessive
moisture. To avoid electric shock, do not open the amplifier. There are no user-serviceable
parts inside.
Your subwoofer and amplifier come in a high quality finish that is both attractive and durable.
To clean, use a soft, damp cloth. If your drivers become dusty, dust them with a paintbrush
or a brush vacuum attachment. Do not use a strong or abrasive cleaner.
The grille is covered in acoustic cloth. To keep your grille clear of debris, we recommend
you use a lint roller (like you would use on clothes).
Bass and Loudness Contour Controls
Do not use bass or loudness contour controls. Induction Dynamics’ subwoofers produce
very low frequencies without these controls. Use of these controls will make the bass sound
“boomy”, obscure higher frequencies, and possibly cause damage due to excessive cone
excursion.
SW4.iw Location
The SW4.iw is designed to be built into walls. Since humans do not hear bass frequencies as
directional, placement is flexible, but it is best to locate the subs near the front sound stage.
Where possible, it is generally best to use two subwoofers, each located in a different area of
the room. In addition to improving efficiency and doubling the power handling, using two
subwoofers creates a more even distribution of the low frequencies by reducing peaks and
nulls. Two SW4.iws must be connected in series.
