General Description :
The Bose® FreeSpace 102F commercial loudspeaker is engineered for true highfidelity performance as part of a distributed sound system. It incorporates a Bose 4.5-inch 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 model requires use of the FreeSpace® system controller or 102 equalizer module, and features 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 passively equalized version (102F-XP, 4Ω) has no transformer, and features an internal passive equalization circuit; thus it does not require a 102 equalizer module or controller.
The 102 loudspeaker has a polyvinylchloride injection-molded enclosure and baffle. This provides a high level of reliability and ruggedness.
Grille and mounting accessories are available.
Equalizer Module:
The 102 equalizer module (102 EQM) provides a simple, cost-effective active equalization alternative to the FreeSpace® system controller. It is specifically designed to be used in commercial-type modular amplifiers that accept 6-pinedge-connector plug-in circuit boards, such as TOA 900 and Peavey MA amplifiers. It is intended to be used only 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.
The 102 flush-mount equalizer module is not intended to replace the FreeSpace system controller. Both units provide the proper active equalization for Bose® 102 loudspeakers. However, the FreeSpace system controller is a two-channel active equalizer with many additional features, such as Opti-voice® paging circuitry, sensitivity adjust, independent microphone equalization, mic/line input and pre-amp. The 102 flush-mount equalizer module makes use of the 102 loudspeaker system feasible in applications where the additional features of the FreeSpace system controller are not necessary.
Engineers’ and Architects’ Specifications:
The loudspeaker shall be a single-driver, full-range system with matched, active equalization (except 102F-XP) as follows:
The transducer complement speaker shall consist of one full-range Helical Voice Coil driver of 4.5 in. (11.4 cm) diameter, mounted on the frontal-facet baffle assembly. The driver shall have a rated impedance of 2 ohms and be wired inparallel with a line voltage-matching (stepdown) transformer with level selector appropriate for various power output taps (except 102F-XP speaker) 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 loudspeakershall be 25 Watts.
The loudspeaker shall be the Bose® 102 flush-mount loudspeaker.
Warranty Information:
The 102 flush-mount loudspeaker is covered by a 5-year, transferable limited warranty.
