Wire Recommendation

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 speaker. The longer your run is, the larger your wire size must be.

Wire Length Wire Gauge
0 -100’ (0 – 30m) 16
50 – 150’ (15 – 45m) 14
Over 100’ (30m) 12

About Speaker Wire

Use a two conductor wire that allows you to identify one conductor from the other. 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.

Subwoofer Placement

The music we hear as bass is made up of frequencies that have long to very long wavelengths (6ft. to 50ft.). Therefore, when a subwoofer is placed into a room, its position in the room will affect the amount of bass perceived by the listener. In other words, placing the speaker in some areas of a room will result in more bass than in other areas of the same room. The more surfaces (walls, ceilings, floors) a speaker is placed next too, the more bass you will hear. An in-ceiling subwoofer mounted in the center of a wall (or ceiling) will gain 3dB of bass if it is moved up the wall (across the ceiling) to where it is adjacent to the ceiling (wall). You can then gain 3dB additional bass by moving the speaker to the corner, where the intersection of three surfaces occurs.

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.

Wire Routing

Plan how you will 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.

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 a special baseboard designed for concealing wires.

Attic or Basement
When available, you can route the wire through an attic or crawlspace.

Through Walls
When running wires through a wall, be sure to avoid all obstacles such as AC wiring, pipes, and ducts.

Under the Carpet
One option is to lift up the carpet and route “tape 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 is 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.

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 gets plugged use a can of compressed air to open it. Once the paint is dry, put the cloth back on the grille.

Cutting the Hole

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. (If you don’t have a template, check 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.

Installing the Bayonet Ring

Adjust the clips so that they’re positioned at the top of the rail. If they’re not already 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.

Connecting the Wire

Insert the wires into the connectors, making sure that the positive wire is being attached to the red connection and the negative wire is being attached to the black connection. If the negative and positive wires are switched, speaker performance will be drastically impacted.

Installing the Speaker

Fit the speaker into the bayonet ring, and twist it clockwise into place. When the arrow on the speaker lines up with one of the arrows on the bayonet ring, that means the speaker is tightly in place. Be sure that the arrows line up, otherwise there’s a risk that the speaker will fall out of the ceiling.

Silicone Sealant: In all applications where moisture is a concern, care should be taken to completely seal the speaker to the bayonet ring (Inner Border ‘A’) and also seal the bayonet ring to the installation surface (Outer Border ‘B’). It is strongly recommended that a liberal bead of marine grade silicone be applied in these two areas. This will improve weather resistance and also assure that mechanical vibrations, like those common in watercraft, will not dislodge the loudspeaker.

Subwoofer & Amplifier Setup

The DBA10EX is a passive subwoofer that requires external amplification. While any amplifier with enough power (100-200 watts) will be sufficient to drive the subwoofer, there are other considerations you will need to address. The DBA10EX is designed to reproduce frequencies below 150Hz. Therefore, running full frequencies to the sub will result in less than optimal performance. If you are using an Audio Video Receiver (AVR) that has Dolby/ DTS processing, there will be a line level, subwoofer output. This output will typically have adjustments to determine the low-frequency crossover point, eliminating the higher frequencies, and a level adjustment. This output CANNOT be plugged directly into the DBA10EX as it is at line level and must first be connected to an amplifier that will boost the signal to speaker level and then connected to the subwoofer. For the highest quality performance, Origin Acoustics has two amplifiers that are specifically designed to drive the DBA10EX as well as other in-wall and in-ceiling subwoofers in the Origin line. The SUBA150 is a dedicated, single-channel subwoofer amplifier with both line level and speaker level inputs. The crossover point, phase and volume level can be adjusted from the front panel to blend the DBA10EX with the satellite speakers in the room. The DSP3-100 is a three-channel amplifier providing 100 watts of power to a dedicated subwoofer channel as well as independent channels for the left and right speakers as well. The versatility of this amplifier is found in the powerful Digital Signal Processing (DSP) that allows for a myriad of adjustments to fine-tune the signal delivered to the subs and satellites. Follow the wiring and set-up instructions included with amplifier you choose.

Installing the Grille

Fit the grille over the speaker. The grille uses magnets to be held in place.


If you have a problem, try isolating it first. For example, if you’re playing a DVD and there is no sound, try replacing the DVD with an MP3 player to see if you get sound. If it does work, then the problem is with the television, DVD player, or the cables connecting them. If it doesn’t work, the problem will be with the amplifier, speakers, or those cables.

Common Solutions



NO SOUND The volume may be turned down or muted. Check the volume settings volume may be turned down or muted. Check the volume settings on both the amplifier and the DVD player/television/computer/etc.
NO SOUND Make sure the proper source is selected on the amplifier or receiver.
NO SOUND Check the cord connecting the amplifier with the source. The cord may be damaged or plugged into the wrong input or output.
NO SOUND Check the wires connecting the amplifier with the speakers. Make sure they’re connected properly and not damaged in any way.
POOR SOUND QUALITY If you hear something like static, or the sound is cutting in and out, check the audio cables. If the problem increases when a cable is being moved, then the cable is most likely faulty or not connected properly.
POOR SOUND QUALITY Today’s audio systems may have several places to adjust the volume, for example your MP3 player may have a volume control, and your amplifier may also have one. Check to be certain that the volume isn’t turned up past 80% on any device.
POOR SOUND QUALITY Try changing sources to be certain that the selection you’ve chosen is a good quality recording.
