Subwoofer Compass-Safe Distance
All speakers and subwoofers contain magnets which are likely to
cause interference with instruments on your boat. The size of
the magnet used in the subwoofer affects how much
interference the subwoofer may cause.
Interference can cause deviations and variations in the readings
of sensitive navigational equipment, such as magnetic
compasses. These deviations can cause inaccuracies or offsets
in the readings, but will not harm the equipment. To alleviate the
deviations, adjust the compass for the deviation following the
manufacturer's instructions or move the subwoofer away from
the navigational equipment. After moving a source of
interference, you may need to recalibrate the compass.
If you are navigating solely by a magnetic compass, use
extreme caution to place the speaker far enough away from the
compass to avoid causing deviations in the readings.
To avoid deviations to navigational equipment, position the
subwoofer so it is separated from the navigational equipment by
at least the distance listed in the table below.

Thiele Small Parameters
You can use the Thiele Small (T/S) parameters when designing
a custom enclosure for your subwoofer.
NOTE: Thiele/Small parameters may vary between samples,
based on the environment and how much the speaker has been
used. These values are intended as a guide to help with
enclosure design.
