Specifications
The loudspeaker shall be a Bogen Model HFSF1 High- Fidelity, Small-Footprint ceiling speaker or approved equivalent, consisting of one 4" (nominal) low-frequen- cy transducer; one 3/4" (nominal) high-frequency trans- ducer; and a filter network for dividing frequencies between the transducers. Frequency response shall be 78 Hz to 20 kHz. Sensitivity, measured 1 watt at 1 meter,shall be 86 dBspl.Max.power input shall be 50W at 16 ohms, or 16W at 70V.
The front baffle shall be injection-molded ABS material and the enclosure (back can) shall be plated steel. All components shall be mounted inside the enclosure.
The baffle bezel shall be supplied in off-white with a mild texture finish to promote paint adhesion, if desired. A perforated steel speaker grille shall be provided, color- matched to the bezel.
The low-frequency driver shall utilize a molded polypropylene diaphragm (cone). A compounded rub- ber surround shall be formulated to withstand environ- mental conditions with high or low heat, high or low humidity, and ultra-violet light.
The high-frequency driver shall utilize a diaphragm con- sisting of black polycarbonate.
Integral swing-out clamps shall provide a secure instal- lation in the ceiling surface. A safety cable attachment point shall be included on the side of the steel enclo- sure.An optional 10-foot long cable kit shall be available to serve as a backup safety cable (Model CK10). An optional tile bridge support installation bracket shall provide additional support when mounting the loud- speaker in suspended ceilings (Model TBSF).
The input connector shall be a 4-screw pluggable input connector, providing loop-through terminals for addi- tional speakers.
Power input selection shall be via a front-mounted rotary switch, located under the removable grille. High- impedance tap selections (70V) shall be 16, 8, 4, 2, and 1 watts. A low-impedance 16-ohm input shall also be available via the rotary switch.
The speaker shall require a minimum vertical clearance of 7-1/8" from the front surface of the ceiling. Overall dimensions of the speaker shall not exceed 7-1/4" Diameter × 7-1/2" Deep.Weight shall be 4.5 lb.
