PRODUCT DESCRIPTION
The FreeSpace® 360P/360 is a full-range environmental loudspeaker intended for background
music and paging. There are three versions. The FS360P 70V/100V, 25W version has an internal
passive equalizer. The FS360P 4 Ohm, 25W version has an internal passive equalizer. The FS360
70V/100V, 25W version requires a Bose
the amplifier.
The FreeSpace 360P/360 can be installed in-ground with approximately one-half of the speaker
exposed above ground. It can also be permanently secured above ground on a horizontal surface
such as a deck.

(Refer to Figure 4)
1. Mounting Plate Removal
1.1 Remove the four screws (20) that secure
the mounting plate (10) to the base housing
(14).
1.2 Lift off the mounting plate.
2. Mounting Plate Replacement
2.1 Align the mounting plate (10) to the base
(14). Replace the four screws (20) that secure
the mounting plate to the base.
3. Driver/Equalizer PCB Removal
Note: For versions without a passive equal-
izer, ignore references to the equalizer PCB.
3.1 Remove the three screws (6) that secure
the driver protector (4) and the driver (1) to the
cap housing (13).
3.2 Lift off the driver protector. The equalizer
PCB is attached by a screw to the driver
magnet. Work the driver with attached equalizer PCB out of the cap housing.
3.3 Cut the wires as close as possible from the
driver terminal. Remove the screw that secures the equalizer PCB to the driver magnet.
4. Driver/Equalizer PCB Replacement
Note: For versions without a passive equal-
izer, ignore references to the equalizer PCB.
4.1 Referring to Figure 6, position the equalizer PCB on the driver and using the screw
removed in procedure 3.3, attach the equalizer
PCB to the driver (1) magnet. Attach the red
wire to the positive (+) driver terminal and the
black wire to the negative (-) driver terminal.
Refer to Figure 1 Wiring Diagram.
5. Transformer Removal
Note: For transformer versions only.
5.1 To gain slack in the wires, perform proce-
dure 3.1 and 3.2 first.
5.2 Remove the four screws (8) that secure
the transformer plate (11) to the cap housing
(13). Lift up the transformer plate.
5.3 Make a note of the wiring configuration
and then remove the wires from the transformer (3).
5.4 Remove the two nuts (9) that secure the
transformer to the transformer plate.
6. Transformer Replacement
Note: For transformer versions only.
6.1 Align the transformer (3) to the transformer
plate (11) and replace the two nuts (9) that
secure the transformer to the transformer
plate.
6.2 Referring to the wiring configuration notes
taken in procedure 5.3 or to Figure 1 Wiring
Diagram, attach the wires to the transformer.
6.3 Lower the transformer with attached
transformer plate into the cap housing (13)
and secure into place with four screws (8).
6.4 Use procedure 4.2 and 4.3 to replace the
driver.

4.2 Work the assembled driver and equalizer
into the cap housing (13). Twist together any
excess wire to prevent a wire buzz.
4.3 Align the driver protector (4), the driver
and the driver gasket (2) to the cap housing.
Replace the three screws (6) that secure the
driver to the cap housing.
