Please read these instructions completely before you begin your installation.

1) Speaker Connection

NOTE: Make sure to use the appropriate type of two-conductor speaker cable for your application.Note that most municipalities require the use of

CL2-rated speaker cable for cable runs through walls and ceilings.

SpeakerWiring: Remove about 8" of the cable jacket to expose the inner conductors. Strip 1/4" of insulation from each conductor and connect to

the speaker terminals.When connecting the wires to the speakers, be sure to observe proper polarity for the best sound.Most CL2 rated speaker

cable has red and black conductors within the jacket, so connect the red wire to the red speaker terminal and the black wire to the black speaker

terminal.The red (+) terminal on the back of the speaker should correspond to the red (+) terminal on the ampliﬁer, and same for the black terminal.

The speaker terminals are of the push-type, so push in on each terminal to allow the wire to be inserted.Torquing the terminal in any way is not

necessary and may cause damage.

NOTE: This speaker is pre-conﬁgured from the factory for 70V/100V operation.This may cause low output when connected directly to an ampliﬁer.

To use this speaker with a conventional (non-70V/100V) audio system, follow the below process to change the 70V/100V tap setting.

Step 1: Remove the grill

The entire grill frame should be

removed by hand;tools are not

necessary, though some force may be

required to dislodge the grill fasteners.

Grasp the frame at a corner, and pull

directly away from the speaker housing.

Step 2: Set 70V/100VTap to 4 OHMS

Using a screwdriver or other ﬂat-

blade tool, turn the tap selector knob

until the 4 OHMS setting is selected.

This will remove the transformer from

the signal path and allow a conven-

tional ampliﬁer to drive the speaker to

full output.

Step 3: Replace Grill Frame

To reinstall the grill frame, align the

pegs on the frame with the openings

on the speaker enclosure, then press

in ﬁrmly. Rotate the logo as required

for proper orientation when installed.

NOTE: If this speaker will be used

with a 70V/100V distributed audio

system, do not set the 70V/100V tap to

the 4 OHMS setting. Doing so may dam-

age your speaker when playing.Instead,

choose the desired 70/100V tap (the one that

provides the desired amount of output) using

the selector switch and the adjustment process described above.The speaker is already pre-conﬁgured

for use with a 70V/100V system.If you are unsure what type of audio system you have, consult a professional installer before continuing.

2) Choose Speaker Location

Because of their well-behaved off-axis response and excellent dispersion, your new Franklin Audio speakers are less critical to position than most

commercial loudspeakers. Simply place them 5-8 feet apart wherever you desire music for the best possible performance.If you will be installing

your speakers outdoors, select locations facing your listening area that are protected from rain, snow, and out of direct sunlight for extended product

life. Because these speakers feature an open bass-reﬂex port, avoid mounting them facing upward in an area exposed to weather to prevent col-

lecting standing water.

3) Choose Speaker Installation

Once you have selected the location for your speakers, you are ready to install them.

CAUTION: Be certain that there are no electrical wires, water pipes, or heating ducts in the planned installation area before you begin drilling. If

there is an electrical outlet nearby, turn off the circuit breaker to avoid possible injury.

NOTE:Your Franklin Audio CS90B speakers are compact, but substantial in weight.They should be mounted into solid structure, not drywall. If

drywall mounting is required, use high-strength anchors designed for heavy loads such as light ﬁxtures.To avoid personal injury, please make sure

the location you choose for mounting your speakers can safely support their weight.

(E) Pendant Mount – Four Speakers Array (Requires Array Bracket Sold Separately)

To mark the proper locations for drilling, place the multi-angle bracket against the mounting surface and choose the holes you want to use for mount-

ing.Then use a pencil to mark the hole locations on the mounting surface prior to drilling.Remove the bracket before drilling the holes, in order to avoid

damage to the bracket.After drilling the mounting holes, install the large half of the bracket ﬁrmly to the mounting surface in the desired orientation using

appropriate mounting hardware.

4) Final Installation

To complete mounting the speaker, choose the desired orientation (vertical or horizontal) and then slide the speaker into the large half of the bracket, then

install the small half of the bracket (the endcap) using the long screws provided.Note:If the speaker does not slide easily into the bracket in the desired

orientation, rotate it 180 degrees and try again.The speaker is intended to slide into the bracket in only one direction.

CAUTION: Do not over-tighten the endcap screws.Too much torque may crack the plastic bracket.A snug ﬁt is all that is necessary to assure proper performance.

5) Troubleshooting

Should your speakers not work properly, check the following:

No sound from speakers or quiet/strange sound:



Make certain you observed proper polarity for both speaker inputs.Check the connections at the back of the receiver, and then at the speaker.

Verify that the ampliﬁer is powered on and the volume is turned up.

Check that the correct transformer tap is selected for your application.If you are using a stereo ampliﬁer or a receiver, use the 4-ohm tap.

Mute feature or protection mode is activated.Check for short circuits in speaker wiring.

One speaker is playing while the other is not playing or plays quietly:

Check the balance control on the receiver.Make sure it is centered.

Loose connection at either the receiver or the speaker.Double check connections.

Bad speaker cable.Replace the suspect speaker cable.

Ampliﬁer/Receiver cuts on and off:

This could be caused by a short circuit between the positive and negative leads.Check the connections at the back of the receiver,

and then at the speaker; make sure that no strands of wire from one connector are touching the other connector.

6) Caring ForYour Speakers

The two most common ways that loudspeakers are permanently damaged:

1) Not enough power at higher volumes.

2) Too much power at higher volumes.

Contrary to conventional wisdom, far more speakers are damaged as a result of under-powering, than by overpowering.When an ampliﬁer runs out of

power, it still tries to reproduce the musical signal by “clipping”the waveform. At high volume levels this clipping sends extreme amounts of distortion

energy to the speaker, eventually destroying it.If the sound from your speakers starts to sound distorted, turn down the volume.

Having plenty of reserve power will help your speakers reproduce dynamic contrasts and quick transients of music much more effectively, but use good

judgment; too much power will also permanently damage a speaker.Again, if you hear distortion or audible distress, turn the volume down.

The CS90B speakers are designed to withstand outdoor environments, including incidental exposure to water.They are not designed to be washed using

a pressure washer or hose nozzle.If debris accumulates on the housing of the speaker, use a damp sponge or cloth to remove it.This product is not suit-

able for washdown duty or locations requiring explosion-proof electrical hardware.
