Bogen Ceiling Subwoofer CSUB User Manual
Page 2
The subwoofer shall be a Bogen Model CSUB or
approved equivalent, consisting of one low frequency
transducer in a band-pass alignment enclosure
design.
The front baffle shall be injection-molded ABS
material and the back can (enclosure) shall be heavy-
gauge steel. All components shall be mounted inside
the enclosure.
The baffle shall be supplied in off-white with a mild tex-
ture finish to promote paint adhesion, if desired. A per-
forated steel speaker grille shall be provided, color-
matched to the baffle.
The driver shall utilize a compounded pulp 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.
Integral swing-out clamps shall provide a secure
installation in the ceiling surface without need for a
separate tile bridge. The clamps shall be operated
from either the front or the back of the speaker.
A safety cable attachment point shall be provided in
the top of the enclosure for adding a 1/4-20 threaded
forged eye bolt. An optional 10-foot long cable kit shall
be available to serve as a backup safety cable (Model
CK10). Use of the CK10 cable kit shall increase the
depth of the speaker, and the minimum vertical clear-
ance required, by 1-1/4".
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 switch, located under the removable grille. High
impedance tap selections shall be 2, 4, 8, 16, 32, and
64 watts. A low impedance 8-ohm selection shall also
be provided.
Dimensions of the speaker shall not exceed 15-1/2"
diameter x 12-1/2" D. The speaker shall require a min-
imum vertical clearance of 11" (from front of mounting
surface). Weight shall be 20 lb.
