Product Description
Thank you for choosing Bogen’s High-Fidelity, Small-Footprint Loudspeaker. Please familiarize yourself with the product by reading and reviewing the descriptions and diagrams in this manual.
Bogen’s coaxial 2-way small footprint ceiling speaker delivers unsurpassed performance and value. The HFSF1 ‘s steel back can and front exit tuned venting allow for extended bass response, enhancing the quality and intelligibility of both speech and music. The very compact diameter and depth dimensions allow for a wide range of installation possibilities in nearly all ceiling spaces.
The HFSF1 can be installed either in suspended ceiling structures or hard surfaces (such as sheetrock). It comes ready to install with integral swinging arm clamps. The Bogen support bracket TBSF is recommended for additional support when the speaker will be installed in suspended ceilings with thin or non-rigid tiles. The optional bracket can also be used for providing a cut-out guide behind a sheetrock ceiling and to stiffen the edges of the cut-out.
A variety of speaker power levels are easily selected via a front panel rotary switch. Settings for both 70V high-impedance systems and 16-ohm low-impedance systems are provided.
The HFSF1 features a removable snap-lock input connector, providing easy wire connection for input as well as loop-through to the next speaker.
Note: The HFSF1 is not an outdoor speaker. Do not expose the speaker to rain or moisture. The HFSF1 should only be installed by qualified personnel.

Installation
Important Notes
The HFSF1 can be installed in a variety of ceiling environments. The use of the TBSF (Tile Bridge Support) accessory may be desired.
For suspended ceilings, the use of both the TBSF Tile Bridge and CK10 Safety Cable is strongly recommended to help support and distribute the weight of the speaker.
The HFSF1 requires a minimum of 7-1/8″ of vertical clearance between the front of the mounting surface and any other structure for the speaker to fit.
The edge of the hole must be a minimum of 1-1/4″ away from any side obstructions to ensure that they will not interfere with the action of the clamps.
Beginning Installation
- Begin by cutting a 6-1/4″ circular hole where the speaker will be installed. A cardboard template is provided with the HFSF1 and should be used as a guide for making the cut-out in the ceiling or sheetrock.
- Tighten the mounting clamps by turning the clamping screws clockwise. Do not overtighten the clamps – only tighten until the speaker is snug in the mounting hole. If using an electric driver, set the clutch on the driver to the lowest setting.
Speaker Wiring
All wiring should be done prior to installation and then plugged into the rear of the speaker. Wiring is terminated at a snap-lock input connector. There are two positive and two negative terminals to accommodate daisy-chaining of speakers in a system.
Daisy-Chaining
The snap-lock input connector allows for easy daisy-chaining of speakers by providing a second terminal of each polarity. See the figures to the right and below for correct wiring for daisy-chaining of terminals.
Note: When speakers are daisy-chained, disconnecting one speaker from the chain will disable all speakers further down the chain.
Speaker Polarity
Keep the same polarity terminals wired together to ensure correct speaker polarity. In order to provide the best possible sound, all speakers in a system need to be pushing out and pulling in at the same time. Therefore all must be wired with the same polarity.
If the connections to one speaker in a system are reversed from the others, that speaker’s movement will be out of polarity with the other speakers. This results in a loss of low frequency response and will effect the overall performance of the system.
Terminal Cover
- The terminal cover is attached to the back of the speaker using 2 screws. It is important that both screws be used to mount the covers.
- A half-round hole in the cover allows the wire to exit the speaker while protecting the connections. A small hole is provided if a wire tie will be used for strain relief.
- If local codes require the use of a conduit for connections or strain relief of the connections, a knockout can be removed and a proper fitting installed for the particular situation.
Selecting Power Levels
The front-mounted selector switch is used to set the appropriate power level or impedance for your system. Using your fingers or a small, flat blade screwdriver, turn the knob until the pointer indicates the power level you require.
70VSystems
Power setting scales for 70V systems are labelled on the speaker.
16-ohm Systems
The fully counter clockwise position of the setting switch is the 16-ohm
position. This setting is suitable for use with low-impedance amplifiers that
typically support 4- or 8-ohm speakers.
The speaker’s higher, 16-ohm impedance makes it easier to combine multiple
speakers into series-parallel networks while keeping the total system
impedance at a level suitable for low-impedance amplifiers.
Speaker Grille installation & Removal
Installation
The speaker grille fits tightly! Push the speaker grille into the slot until it is fully seated. The edge of the plastic bezel and the grille will be approximately flush when the grille is properly seated.
Removal
Insert a small flat-blade screwdriver or a thin pocketknife blade between the
grille and the bezel about 1i8″ deep and gently pry the grille upwards. Do
this in several places around the grille until it is free.
Specifications
- Half-Space Response, 16-ohm input Front panel, switch-selected.
