OWNERS MANUAL
INTRODUCTION
Congratulations on your purchase of DCM Loudspeakers. Your new speakers
represent the latest technologies in loudspeaker design and manufacturing. They
will provide outstanding performance and years of listening enjoyment. Please
take time to read through this manual thoroughly to insure you get maximum performance out of your new loudspeakers.
Your speakers are designed to work with a wide range of electronic components.
As little as 20 watts per channel can provide enough power for most applications.
If you have a large room or prefer louder listening levels, more power may be
required.
Caution: When choosing an amplifier, do not exceed the power rating of the
speaker. If you hear very high levels of audible distortion you are exceeding the capabilities of the system. Damage can occur from this distortion,
turn the volume back down until the distortion disappears.
FEATURES
• Video shielding for placement near a TV or monitor
• Extended bandwidth constant directivity horn loaded tweeter
• Polypropylene cone midrange with pole mounted phase plug
• Large excursion, pulp cone woofer (DCM10, DCM12) with extended, vented
pole piece for improved power handling

CARE AND MAINTENANCE
the cabinet
Use the following guidelines to maintain the appearance of your speakers. Use a
soft, damp cloth to clean the speaker cabinet. Avoid using harsh detergents or
cleaning fluids. Remove the grills to vacuum and remove dust. Do not vacuum
any of the speaker components, permanent damage could occur.

SPEAKER PLACEMENT
MAIN LEFT AND RIGHT CHANNELS
DCM6, DCM10, DCM12
All DCM Loudspeakers have been engineered to combine deep powerful bass
with crisp, natural high frequency performance. Because there are many factors
that affect loudspeaker performance, there is no universal rule for speaker location. Best results will be obtained with some experimentation using the following
guidelines.

MODEL# _______________________________
NAME _____________________________________________________________________________
To achieve the most realistic stereo image, position the speakers so that an equilateral triangle is formed between the speakers and the listening position (Figure 1).
Turning the speakers slightly towards the listening position can improve the image
focus.
Bass loudness can be increased by moving the speakers closer to the rear wall.
This sometimes can degrade the stereo image. Use your judgement as to what
location best fits your preferences.
SURROUND LEFT AND RIGHT CHANNELS
DCM6
If you are using the DCM6 for rear channel speakers in a home theater application they should be placed on the side walls and slightly behind the listening position (Figure 1). If this is not practical, they can be placed on the rear wall to either
side of the listening position (Figure 2). For best results, the surround speakers

CENTER CHANNEL
DCM6C
HOOK UP
When using the DCM6C as a center channel speaker in a home theater application the following guidelines should be used for optimum performance.
Use 16 gauge or heavier speaker wire for connecting to your amplifier or receiver. Cut wire lengths leaving an extra 12” to 24” at each end to allow for moving
the speaker or receiver.
Locate the speaker as close to the center of your TV or monitor as possible
(Figure 1). This will anchor the central image of your home theater to the location
of the images seen on the screen.
Place the center channel at an equal distance to the listening position as the main
speakers are. Also, place the height of the center channel’s tweeter as close to
the same height as the main speakers’ tweeters (Figure 3). This will prevent
image blurring when sounds are panned from the one side of the room to the
other.
Using a wire cutter or a sharp knife, strip 1/2” of insulation off each end of the wire
to expose the conductor. Twist wire ends to prevent from fraying. Connect the
conductors to the binding posts on the bottom or back of the speaker by unscrewing the post enough to expose the hole in the terminal post. Slip the exposed conductor in the hole and tighten the post. Repeat this step for connecting to your
amplifier or receiver. Refer to the owner’s manual supplied with your electronics
to assist with proper hook up.
Note: To ensure proper performance, make sure that the wire from the red
(+) terminal on the speaker is connected to the red (+) terminal on your
amplifier or receiver. Likewise, make sure the wire from the black (-) terminal on the speaker is connected to the black (-) terminal on the amplifier or
receiver. (Figure 4)

FIGURE 4 Connecting Speakers to Amplifier or Receiver
Once your speakers are hooked up, turn on your electronics and test to make
sure they are functioning properly. If your speakers sound “thin” with little bass
and have a poor center image, one of the speaker wires is probably hooked up
backwards. Double check all connections for proper polarity.
