High-Fidelity,

Small-Footprint Speaker

Model HFSF1

Installation and Use Manual

Product Description

Thank you for choosing Bogen’s High-Fidelity, Small-Footprint Loudspeaker. Please famil-

iarize 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 possibili-

ties in nearly all ceiling spaces.

The HFSF1can 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 cutout guide behind a sheetrock ceiling and to

stiffen the edges of the cutout.

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 HFSF1features a removable snap-lock input connector, providing easy wire con-

nection 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 HFSF1can 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

Saftey Cable is strongly recommended to help support and distribute the

weight of the speaker.

The HFSF1requires 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

1. Begin by cutting a 6-1/4" circular hole where the speaker will be installed. A

cardboard template is provided with the HFSF1and should be used as a guide

for making the cutout in the ceiling or sheetrock.

2. Tighten the mounting clamps by turning the clamping screws clockwise. Do not

over-tighten 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 con-

nector. There are two positive and two nega-

tive 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 sec-

ond 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 polari-

ty. 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.

70V Systems

Power setting scales for 70V systems are labeled

on the speaker.

16-ohm Systems

The fully counterclockwise position of the set-

ting switch is the 16-ohm position.This setting is suitable for use with low-imped-

ance 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-imped-

ance 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 pock-

etknife blade between the grille and the bezel about

1/8" deep and gently pry the grille upwards. Do this in

several places around the grille until it is free.
