Data Sheet
The loudspeaker shall be a Bogen Model HFCS1 or
HFCS1LP Ceiling Speaker or approved equivalent, con-
sisting of one 6-1/2" (nominal) low frequency transducer,
one 3/4" (nominal) high frequency transducer, and a filter
network for dividing frequencies between the transducers.
The front baffle shall be injection-molded ABS material
and the back can (enclosure) shall be made of steel.
All components shall be mounted inside the enclosure.
The baffle shall be supplied in off-white or black (B ver-
sions) with a mild texture finish to promote paint adhe-
sion, if desired. A perforated steel speaker grille shall be
provided, color-matched to the baffle.
The low-frequency driver shall utilize a molded polypropy-
lene diaphragm (cone). A compounded rubber cone
surround shall be formulated to withstand environmental
conditions with high or low heat, high or low humidity, and
ultra-violet light.
The high-frequency driver shall utilize a diaphragm
consisting of black polycarbonate.
Integral swing-out clamps shall provide a secure installa-

An optional tile bridge/support ring installation bracket
(Model TBCR) shall provide additional support when
mounting the loudspeaker into suspended ceilings. The
bracket shall also serve as a pre-installation guide for new
construction installations, and provide attachment to either
16" OC or 24" OC mounting.
The input connector shall be a 4-screw pluggable input
connector, providing loop-through terminals for additional
speakers.
Power input selection shall be via a front-mounted rotary

Dimensions of the speaker shall not exceed 12-5/16"
diameter x 12" D (HFCS1/B) or 12-5/16" diameter x
7-3/4" D (HFCS1LP/B). The speaker shall require a min-
imum vertical clearance of 11" (HFCS1/B) or 6-3/4"
