General Description
The BOSE
®
102
®
F commercial loudspeaker is engineered for true high-
fidelity performance as part of a distributed sound system.
It incorporates a BOSE
®
4.5-inch (11.4 cm) HVC (Helical Voice Coil) full-
range 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.
The 102
®
loudspeaker has a polyvinyl-chloride injection-molded
enclosure and baffle. This provides a high level of reliability and
ruggedness. Grille and mounting accessories are available.

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, Part 16: The objective rating of speechintelligibility in auditoria by the “RASTI” 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, Part 5: Loudspeakers, page 53).
