BOSE® FreeSpace® 102®F loudspeaker
TECHNICAL DATA SHEET
General Description
The BOSE® 102®F commercial loudspeaker is engineered for true highfidelity performance as part of a distributed sound system.
It incorporates a BOSE® 4.5-inch (11.4 cm) HVC (Helical Voice Coil) fullrange driver in a dual-ported enclosure.
The 102® flush-mount speaker can be installed in ceilings and standard
studded walls. The actively equalized models require use of their active
equalization curve available in select Bose electronics, and feature a
factory installed line transformer with 2, 4, 8, 16, and 25 Watt taps.
The front panel of this version contains a level tap switch that is easy to
adjust with a screwdriver.

Safety Standards
The BOSE® 102® flush-mount speaker is UL listed under UL standard
1480, complies with ANSI/EIA-636, and when properly installed
complies with NFPA-70 (NEC). The speaker has a flammability rating
of 94-5V. Suitable for use indoors in damp locations. Suitable for use in
air handling plenum spaces when used with a backcan.
Electrical Connections
1. Loosen the wiring-well rear cover screws; swing the cover to one side.
2. Route the source wires through the appropriate entryway and secure
with the supplied strain relief.
3. Using the supplied wire nuts, connect the positive source wire to the
speaker’s black lead.
4. Fit the leads into the portion of the well where the speaker leads
emerge (not where the transformer and switch are located).
5. Reseat the wiring-well cover; tighten the cover screws.
1 Sensitivity is measured according to the standard established by the International Electrotechnical Commission
(IEC Publication #268 -5, Sound System Equipment, Part 5: Loudspeakers, page 31). Special random noise spectra used other than pink noise are described below.
2 Speech sensitivity is measured using pink noise shaped to an average speech spectrum as defined by the InternationalElectrotechnical Commission (IEC Publication #268-16,
Sound System Equipment, Par t 16: The objective rating of speechintelligibility in auditoria by the “R ASTI” method, page 19).
3 Music sensitivity is measured using pink noise shaped to an average music spectrum as defined by the International Electrotechnical Commission ( IEC Publication #268-5,
Sound System Equipment, Par t 5: Loudspeakers, page 53).

Optional Grille Accessories
The 102® Speaker Snap-On Grille
This durable, high-pressure injection-molded vinyl grille has a flat white
exterior finish that can be painted.
Its ratchet mechanism allows quick, secure installation with no tools
or fastening hardware required. Grilles are packaged as singles and 8
per carton.
1. To attach, push up and snap in place.
2. To remove, press at the center of the grille, while pulling down
at its edges.
The 102 Flush-Mount Speaker Grille Adapter
This is used to adapt standard ceiling speaker grilles to fit the ratchet
system of the 102 passive flush-mount speaker. Adapters are sold
individually. Order part number 127589.
Engineers’ and Architects’ Specifications
The loudspeaker shall be a single-driver, full-range system with matched,
active equalization as follows:
The transducer complement shall consist of one (1) full-range Helical
Voice Coil driver of 4.5-inch (11.4 cm) diameter, mounted on the frontalfacet baffle assembly. The driver shall have a rated impedance of 2
Ohm and be wired in parallel with a line voltagematching (stepdown)
transformer with level selector appropriate for various power output
taps which are 2, 4, 8, 16, and 25 Watts.
The loudspeaker shall be provided with an annular ported vent system,
tuned to 80Hz. The input connection shall consist of dual solid 18-gauge
wires. The molded plastic enclosure shall incorporate a strain relief
system for mounting either bare wire or conduit to the rear panel of the
loudspeaker.
The enclosure shall be constructed of PVC-type vinyl resin with a
flammability rating of 94-5V. Outer dimensions shall be: 11.75 in (30 cm)
diameter by 3.75 in (9.5 cm) depth. Weight shall be 5 lb ( 2.3 kg).
The loudspeaker sensitivity shall be 86dB SPL measured at 1 Watt,
1 meter, and its operating bandwidth shall be 80Hz to 18kHz (±3dB).
The nominal coverage angle shall be 150 degrees conical.
The power handling capacity of the loudspeaker shall be 25 Watts.
The loudspeaker shall be the BOSE® 102® flush-mount loudspeaker.
Use of Metal Backcans
The requirement for backcan use with loudspeakers in a commercial
or public space is usually based on the local inspector’s interpretation
of applicable codes. The BOSE® 102® flush-mount loudspeaker will fit
into these standard backcans:
> Atlas/Soundolier models 95-8-7 and 96-8-7
> Lowell Manufacturing models CP87 and XCP87-S (without torsion
receptacles)
NOTE: The BOSE® 102® flush-mount loudspeaker does not
fit into tapered, stackable backcans.
Equalizer Module
The 102 equalizer module (102 EQM) provides active equalization for the
FreeSpace® 102F loudspeaker. It is specifically designed to be used in
commercial-type modular amplifiers that accept 6-pin edge-connector
plug-in circuit boards, such as TOA 900 and Peavey MA amplifiers. It is
intended to be used with the actively equalized 102 flushmount
loudspeaker. The module provides system equalization for all inputs on
the amplifier, and includes stereo (summed to mono) unbalanced audio
inputs. The AUX input is muted whenever the amplifier muting bus is
shorted to ground.
