Because of their well-behaved off-axis response and excellent dispersion, your new Dayton 
Audio speakers are less critical to position than most loudspeakers. Simply place them 5-8 
feet apart wherever you desire music for the best possible performance. If you will be install-
ing your speakers outdoors, select locations facing your listening area that are protected from 
rain, snow, and direct sunlight for extended product life.

  

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

Your Dayton Audio indoor/outdoor 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 indoor/outdoor speakers can 
safely support their weight.

To mark the proper locations for drilling, remove the yoke-style mounting brackets from the 
rear of the speaker enclosures by removing the endcap screws, which are the large, round 
plastic dials at either end of the speaker. Place the yoke bracket against the mounting surface 
and choose the holes you want to use for mounting. Then use a pencil to mark the hole loca-
tions on the mounting surface prior to drilling. Remove the yoke bracket before drilling the 
holes, in order to avoid damage to the yoke bracket.

After drilling the mounting holes, install the yoke bracket firmly to the mounting surface using 
the supplied mounting hardware.

Don’t compromise sound quality by using thin, inexpensive speaker wire. We recommend 
using a high quality oxygen free copper two-conductor speaker cable. For low-impedance 
applications (8 ohms) and runs less than 50 feet we recommend 16 gauge cable, and for 

longer runs we recommend 14 gauge or larger cable. (Wire size is less important for 70-volt 
distributed audio applications but may still affect performance.) Note that most municipalities 
require the use of CL2 rated speaker cable for cable runs through walls and ceilings. Leave 
enough excess speaker cable so you can stand comfortably on the floor or ladder while con-
necting the speaker cable to the speakers. If mounting the speakers outdoors, you may wish 
to fill the hole that the speaker wire passes through with a caulking material to prevent water 
intrusion and cold air infiltration.

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.

Note: If you have an 8-ohm model, no further configuration is necessary. If you are installing 
a distributed 70-volt (70V) system, be sure to use the appropriate speaker model (70V ver-
sion) and use the selector knob on the rear of the speaker to choose the transformer tap that 
provides the desired acoustic output. When the 70V model is used with a 70V system, do not 
select the “8-Ohm” tap.

To install the speakers into their final location, place them into the yoke brackets and align the 
threaded inserts in the enclosure for the endcap screws with the matching holes in the yoke 
brackets, then install the endcap screws. Select an angle for the enclosure that will allow the 
entire listening area to be within line-of-sight of the tweeter dome, which is visible through the 
grille, and then tighten the endcap screws by hand. At this time, installation is complete.

If you choose to paint the speaker grill and/or housing, be sure to cover the woofer and 
tweeter, which are not paintable. Also do not paint the terminals or threaded inserts. Remove 
the grille for painting separately from the enclosure. Do not try to paint the frame and grill 
assembly together -- the grill should always be painted separately. Do not apply heavy coats 
of paint to the grill that might block the perforations in the grill and decrease audio output. Ap-
plication by spraying is recommended.

9)  Troubleshooting
 

Should your speakers not work properly, check the following:

 

 

 

●

  Make certain you observed proper polarity for both speaker inputs. Check the 

connections at the back of the receiver, and then at the speaker.

 

 

 

●

  Most stereo receivers have an A/B speaker selector switch. Make certain that 

this switch is in the proper position, and that the proper audio source is selected.

 

 

 

●

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

 

 

 

●

  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 suspect speaker cable.

 

 

 

●

  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.
