In this mode, one channel is fed into both tweeters to be distributed throughout
the area. This way in a multiple-speaker setup, one speaker can be a dedicated
le speaker and another a dedicated right.
Surround (Dipole)
The Dual Tweeter models can be used for either one channel (surround) or two
channels (stereo). A switch is located on the back of the speaker to select which
mode to use. One of the inputs is labeled for surround. This is the input that
should be used if you’re only using one channel.
Dual Tweeters
In this mode, two channels are fed into the speaker: one channel for each tweeter.
This setup is ideal for small rooms such as walk-in closets and bathrooms, as well
as oddly-shaped areas such as hallways. With both le and right channels in one
speaker, only one speaker is needed in smaller rooms. In areas like hallways, both
channels can be evenly distributed throughout the area with multiple speakers.
Stereo (Dipole)
If you are using a dual tweeter speaker in stereo mode (i.e. there are two wires
connected to the speaker: one for the le channel and one for the right), do not
set the switch to surround mode. This could damage the amplifier.

Tools & Items
The gauge of wire used can have an impact on the performance of your speakers.
Use a multi-stranded wiring designed for amplifier to speaker connections. Which
gauge to select depends on the length of wire to be used on any particular speak-
er. The longer your run is, the larger your wire size must be.
Wire Recommendation
Wire Length Wire Gauge
0 -100’ (0 - 30m) 16 (1.5mm²)
50 - 150’ (15 - 45m) 14 (2.5mm²)
Over 100’ (30m) 12 (4mm²)

Ideally, the two speakers should be
placed an equal distance from the lis-
tener. If the room has a lower ceiling,
the speakers can be closer together.
Also, if the speaker placement is in-
tended for standing (as opposed to
sitting) listeners, the speakers can be
closer together.
Auxiliary Room (2 Speaker Placement)
The Le Rear (LR) and Right Rear (RR)
speakers should be installed just be-
hind the listener, one on either side.
The Center Channel (CC) speaker
should be placed above and slightly
in front of the television, with the Le
Front (LF) and Right Front (RF) speak-
ers placed equidistant to either side.

Strip ¼ to ½ inches (6 to 12 mm) of the
insulation o both ends of the wire. To
avoid stray strands, twist them at the
end. Connect the wire to the amplifier,
and make sure the wire connected to
the le speaker output will be routed
to the le speaker, right output to right
speaker, etc.
1. Installing the Wire
Use a two conductor wire that allows you to identify one conductor from the oth-
er. This designation may be obvious or as subtle as a ridge on one conductor.
It’s crucial that you keep track of which wire you use for positive (+) and negative
(-). Typically if the wires are colored red and black, the red wire is used for positive
and the black wire is used for negative, but sometimes other colors or patterns
are used. You can choose whichever color of wire you want to be positive and
negative as long as you remain consistent throughout the install.
On both your amplifier and your speaker the connectors will be identified as red
for positive and black for negative. It is very important to look carefully at the
speaker wires and be certain that the same wire that is attached to the positive
connector in the amplifier is attached to the positive connector in the speaker.

Plan how you’ll route the wire to the desired speaker location. There are several
methods for routing the wire, and you may need to combine several of them.
Wire Routing
One option is to li up the carpet and
route “tape wire” under the carpet.
Under the Carpet
The wire can be routed behind the
baseboard by cutting a groove out of
the back of the baseboard, or by buy-
ing special baseboard designed for
concealing wires.
Behind the Baseboard
When available, you can route the wire
through an attic or crawlspace.
Attic or Basement
When running wires through a wall, be
sure to avoid all obstacles such as AC
wiring, pipes, and ducts.
Through Walls
If these speakers are being installed in a new home during construction, the
installation process will be a bit dierent (although much simpler). For these
situations, it’s recommended you purchase a bracket. Instructions on how to
install the speakers are provided with the bracket, or can be found on our web-
site. Visit www.originacoustics.com for more information.
For New Construction

Adjust the clips so that they’re positioned at the top of the rail. If they’re not al-
ready there you can do this by pushing the metal release tabs on the inside of the
rail and pulling the clips to the top of the rails. Insert the bayonet ring into the hole
in the ceiling by gently bending the rails inward. Reach inside the bayonet ring
and push the clips down so that the bayonet ring is firmly in place, but not too
tight. If the bayonet ring needs to be removed, reach inside and push the release
tabs to reset the clips The bayonet ring can now be taken out.
When you’ve decided on the locations for all of the speakers, use the template to
trace a circle lightly in pencil where the hole should be. (Refer to the Specifications
section for cutout sizes.) If you’re unsure on whether there may be obstacles (such
as pipes or wires) where you plan on installing the speaker, drill a ⅛ inch hole
in the center of the circle, then put a bent coat hanger through the hole to feel
around. Use a keyhole or drywall saw to cut the hole.
