FIRST CLASS STAMP HERE DCM6C 7676 S. 46th Street PHOENIX AZ 85040-6400 DCM6 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 • Internally braced cabinets using Modal Reduction Technology (MRT) • Down firing ports with large radius flare. • Nickel-plated 5-way binding posts mounted on the bottom of (DCM10, DCM12) 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. TECHNICAL ASSISTANCE For additional technical assistance you can visit our website at www.dcmspeakers.com.

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. (This registration must be filled out and mailed within 10 days of purchase to validate warranty.) WARRANTY REGISTRATION 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 STREET ___________________________________________________________________________ CITY _____________________________________ STATE _____________ ZIP _________________ DATE PURCHASED _________________________ PLACE PURCHASED ________________________________________________________________ Purchased as a: Packaged System ( ) Speakers Only ( ) Replacement System ( ) Extension Speakers ( ) If replacement, what is the name and model number of the system replaced?

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.

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.
