Location Hazards
It is the nature of low-frequency energy (bass) to make objects vibrate. Care should be taken in planning
the installation of the in-floor subwoofer to minimize the risk of room vibration and noise. Do not locate
the in-floor subwoofer close to lamps or furniture that might rattle or vibrate. Some bass energy will be
heard in the room below the subwoofer. If the ceiling below is finished, ceiling fixtures may rattle or
vibrate.
It is recommended that in the area where the Sub10F is to be mounted, the subfloor is glued to the
joists and extra nails are used to secure the subfloor. Be sure the joists to which the Sub10F is mounted
are securely braced against each other so that the distance between them does not change and they
are not able to move or shift (consult local building codes)
Amplifier Requirements & Wiring
The Sub10F must be used with the Boston SA1 Subwoofer Power Amplifier. Use with any other amplifier
will result in poor performance. One SA1 Power Amplifier can power up to two Sub10F subwoofers.
Only one Sub10F should be connected to each set of terminals on the SA1. If you are installing only one
Sub10F, pre-wire so that a second one can be added, but do not connect the extra set of speaker wires
to the SA1.
Set the equalization switch (EQ-MODE) on the back of the SA1 amplifier to the “FLOOR” position. We
recommend the use of 16-gauge or larger speaker wire with both the Sub10F and SA1.
Service Access
If service is needed, the Sub10F’s woofer can be removed through the access panel on the bottom of
the subwoofer. If there is a finished ceiling below the Sub10F, ideally a door allowing access to the
complete subwoofer enclosure, or at minimum, to the Sub10F’s service panel, should be left in the ceil-
ing below.
