Product Description

Thank you for choosing Bogen’s High-FidelityCeiling Loudspeakers. Please familiarize yourself with the product by reading and reviewing the descriptions and diagrams in this manual.

Bogen’s coaxial 2-wayhi-ficeiling speakers deliver unsurpassed performance and value. The HFCS1(LP)’s steel back can and front exit venting allow for deep bass response, enhancing the quality and intelligibility of both speech and music. The HFCS1LP uses a smaller,low-profileback can that allows for a greater range of installations.

Both speakers can be installed either in suspended ceiling structures or hard surfaces (such as sheetrock). They come ready to install with integral swinging arm clamps. An optional mounting bracket (TBCR) is available for additional support (recommended for all suspended ceiling applications).The bracket can also be used for new construction ceilings, providing a cutout guide behind the sheetrock surface and as a C-ringto stiffen the edges of the cutout opening.

A variety of speaker power levels are easily selected via a front panel rotary switch. Settings for both 70V and 100V high-impedancesystems, as well as alow-impedance(16-ohm)position, are provided.

The HFCS1(LP) features a removable snap-lockinput connector, providing easy wire connection for input as well asloop-throughto the next speaker.


The HFCS1 and HFCS1LP are not outdoor speakers. Do not expose the speakers to rain or moisture.The HFCS1 and HFCS1LP should only be installed by qualified personnel.

The HFCS1 and HFCS1LP can be installed in a variety of ceiling environments.The use of the TBCR (Tile Bridge Support Ring) accessory may be desired for many of these.

For suspended ceilings, the use of a TBCR is strongly recommended to help support and distribute the weight of the speaker.

In new construction installations the TBCR, installed before sheetrock, acts as a routing template that ensures an accurate and neat hole for installation. The TBCR can also be used as a support ring in retrofit applications to better distribute the speaker’s clamping forces.


The HFCS1 requires a minimum of 11" of vertical clearance between the FRONT of the mounting surface and any other structure for the speaker to fit.The HFCS1LP requires a minimum of 6-¾"of vertical clearance.

Before cutting the full hole, use a smaller exploratory hole to determine if there are any obstructions.

The edge of the hole must be a minimum of 1-¼"away from any side obstructions to ensure that they will not interfere with the action of the clamps.

1. Begin by cutting a 10-¾"circular hole where the speaker will be installed. If using a TBCR, then follow its installation instructions for the specific type of environment the speaker is being installed in.

2.Make electrical connections to the pluggable terminal strip and plug it onto the speaker. See Speaker Wiring section.

3.Install terminal cover plates, if necessary or desired, using 4 screws. See the Terminal Covers section if using conduit or if it is required to secure the speaker directly to the structure (typically for suspended ceilings).

4.Remove the speaker’s grille (if neccessary). See Speaker Grille Installation & Removal section.

5.Set the power level using the rotary selector switch on the front panel. Refer to the Selecting Power Levels section for instructions on selecting the power level.

6.Position the swing-outclamps so that they are against the body of the speaker and insert the speaker into its opening in the ceiling.

7.Tighten the clamps by turning the clamping screws clockwise. Do not over-tightenthe clamps - only tighten until the speaker is fairly snug in the mounting hole. If using an electric driver, set the clutch on the driver to the lowest setting.

8.(Re)install the speaker’s grille. See Speaker Grille Installation & Removal section.


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-lockinput connector. There are two positive and two negative terminals to accommodatedaisy-chainingof speakers in a system.


The snap-lockinput connector allows for easydaisy-chainingof speakers by providing a second terminal of each polarity. See the figures to the right and below for correct wiring fordaisy-chainingof terminals.

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 Covers

The two terminal cover halves are attached to the back of the speaker using 4

screws. It is important that all 4 screws be used to mount the covers.

A slot between the two halves allows the wire to exit the speaker while protecting the connections.The cover's eyelets can be used to anchor the wire using a wire tie if desired.

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.

Eyelets are provided on the terminal covers to provide a means of securing the speaker to the structure. It is important that all 4 terminal cover screws be installed in this application.A Bogen Model CK10 cable will accomplish this.


Selecting Power Levels

The front-mountedselector switch is used to set the appropriate power level or impedance

for your system. Using a small, flat-bladescrewdriver, turn the knob until the slot points to the power level you require.

70V/100V Systems

Both power setting scales for 70V and 100V systems are labeled on the speakers. On the

100V scale, the last position clockwise is marked with a symbol. Do not use this position in 100V systems.


The fully counterclockwise position of the setting switch is the 16-ohmposition.This setting is suitable for use withlow-impedanceamplifiers that typically support 4- or8-ohmspeakers.The speaker’s higher,16-ohmimpedance makes it easier to combine multiple speakers intoseries-parallelnetworks while keeping the total system impedance at a level suitable forlow-impedanceamplifiers.

Speaker Grille Installation & Removal


The speaker grille fits tightly! Push the speaker grille in until it can go no further. Then, slap around the edge of the grille to seat the grille.The grille is properly seated when it is flush with the edge of the bezel.


Insert a pocketknife blade between the grille and the bezel about 1/4" deep and then gently pry the grille upwards. Do this in multiple places around the circumference of the grille to free the grille.
