Installation
1) Installing the Wire
Strip ¼ to ½ inches (6 to 12 mm) of the insulation off 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 left speaker output will be routed to the left speaker, right output to right speaker, etc.

About Speaker Wire
You will need a wire that has at least two conductors; one that can be identified as the positive and the other as the negative. All two conductor wires have some means of identifying which conductor is which, but at times this identification may be subtle. 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 out how you’ll route the wire to the desired speaker location. There are several methods for routing the wire, and you will most likely need to combine several of these methods.
Under the Carpet:
One option is to lift up the carpet and use tape wire to route the wire under the carpet.
For New Construction
If these speakers are being installed in a new home during construction, the installation process will be a bit different (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 website. Visit www.originacoustics.com for more information.
Behind the Baseboard:
The wire can be routed behind the baseboard by cutting a groove out of the back of the baseboard, or by buying special baseboard designed for concealing wires.
Through the Attic:
If the room is under the attic or a crawlspace, the wire can be routed through there.
Through the Basement:
Likewise, if there’s a basement or crawlspace under the floor, the wire can be routed through there.
Route the wire through the walls and ceiling to the desired speaker location. Be sure to avoid all obstacles such as AC wiring, pipes, and ducts.

2) Painting the Grille
In some situations the speakers may look better if the color matched the walls, ceiling, or trim in the room. This can be accomplished by painting the grille. The grille must be painted with spray paint, and most hardware stores will mix a can of paint to match whatever color you need.
Before painting, carefully remove the thin cloth on the underside of the grille. Lightly spray the front of the grille with the paint from a distance, being careful not to plug any of the holes. Diluting the paint with paint thinner will lessen the risk of filling any holes. If a hole is plugged, use a can of compressed air to open it. Once the paint is dry, put the cloth back on the grille.

3) Cutting the Hole
When you’ve decided on the locations for all of the speakers, use the template to trace a rectangle lightly in pencil where the hole should be. 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 rectangle, then put a bent coat hanger through the hole to feel around. If there are no obstacles, use a keyhole or drywall saw to cut the hole.
4) Connecting the Wires
Push down on the top of the connector and insert the wire, making sure that the positive is being attached to the red connection and the negative is being attached to the black connection. If the negative and positive wires are switched, speaker performance will be drastically impacted.

5) Installing the Speaker
On the speaker, make sure all the SpringLocks are loaded in the upper notch, facing inward. Fit the speaker into the hole, and using a screwdriver or a coin, turn the SpringLock releases 90 degrees so the
SpringLocks face outwards.
When you turn each SpringLock release, you should hear each
SpringLock clamp down on the wall. Do not attempt to tighten the SpringLock releases, because once the SpringLock has clamped down it’s as secure as it can be.
If you need to remove the speaker, turn the SpringLocks
90 degrees so that they face inwards and lift the speaker out.

6) Listening Test and
Adjustments
The tweeter can be pivoted to direct the sound towards the listening area. Gently apply pressure to the rim of the tweeter with your thumbs to aim.
The LCR36, LCR38, LCR66, and
LCR68 have two switches: one to adjust the treble, and one to adjust the bass. The LCR64 only has one switch for treble.

Figure 11.2: Bass/
Treble Switches
Reasons to Adjust Bass and Treble
Bass: When a speaker is installed in a corner, the bass is amplified. If this is the case, it may be best to turn the bass down.
Treble: When a room has a lot of hard surfaces like bare walls and hardwood floors, the treble will reflect off of these surfaces and increase. In these situations, it may be a good idea to turn the treble down. Alternately, in rooms with carpet and things like curtains, the treble is often absorbed. If this is the case, it would probably be best to turn up the treble.
7) Installing the Grille
Fit the grille over the speaker. The grille uses magnets to be held in place.
