Several levels of power output can be controlled directly from the front baffle via a rotary tap selector switch under the grille. The low-distortion, coaxial-design speaker, coupled with a computer-matched venting system, delivers superb fidelity for music as well as high intelligibility for voice reinforcement. Coupled with the Bogen CSUB Ceiling Subwoofer, it provides the perfect solution for environments that require the highest-quality sound with minimal visual impact. Features • Superior sound in a very compact enclosure • Wide-dispersion coaxial driver for broad, even coverage; superb off-axis response • Small footprint, visually appealing • Only 7-1/4" face diameter • Installs in wide range of ceiling types • For 70V and low-impedance systems • Selectable power taps via front-mounted control (under grille); 16, 8, 4, 2, 1 watts at 70V • 16-ohm Input setting for low-impedance systems (selectable via front-mounted control, under grille) • Quick wiring with removable plug-in connector • Plug-in connector provides loop-through terminals for next speaker • Terminal cover provides knockout for flexible conduit connection • Compounded rubber surround for lasting performance year after year • Integral mounting clamps tighten quickly and firmly • Attachment point for seismic safety cable • Off-white textured finish easily painted to match room decor • Available accessories: Tile Bridge Support (TBSF), Safety Cable (CK10), both sold separately Specifications subject to change without notice. © 2008 Bogen Communications, Inc. 54-8023-38B 1202 Frequency Response*: 78 Hz to 20 kHz " Polypropylene cone with rubber surround " Polycarbonate dome Low (16 ohms), High (70V) 50W at 16 ohms, 16W at 70V - Powder-coated, perforated metal erminal Snap-lock input connector Snap-lock input connector (1) Steel terminal cover (1), with (2) mounting screws Suspension/Safety Cable (CK10) ile Bridge Support (TBSF) * 1/2-Space response (ceiling-mounted), 16-ohm input † Front panel, switch-selected Architect & Engineer Specifications Technical Specifications The loudspeaker shall be a Bogen Model HFSF1 High- Fidelity, Small-Footprint ceiling speaker or approved equivalent, consisting of one 4" (nominal) low-frequency transducer; one 3/4" (nominal) high-frequency trans- ducer; and a filter network for dividing frequencies between the transducers.
