Frequently Asked Questions - DX-C390 KLIPSCH
How do I connect the Klipsch DX-C390 to my amplifier?
Turn off the amplifier before connecting. Use the gold-plated binding posts on the DX-C390 and match polarity: red to red, black to black. Loose or incorrect connections can cause poor sound or damage.
What is the recommended amplifier power for the DX-C390?
Klipsch recommends using an amplifier rated between 15 and 150 watts per channel into 8 ohms. The high sensitivity of 92 dB means moderate power levels provide satisfying volume, but ample headroom helps avoid clipping.
Where should I place the DX-C390 for best sound?
Place the speakers at ear level on stable stands or bookshelves. Keep them at least 20 cm from a wall to reduce bass boom, and angle them toward the listening position for a focused stereo image.
Can I use the DX-C390 as a center channel speaker?
Yes. The DX-C390 is designed for flexible placement and can be used as a center speaker in a home theater setup. Align it with the screen and use the receiver’s crossover, usually 80 Hz, to blend with a subwoofer.
How do I clean and maintain the DX-C390?
Clean the cabinet with a soft dry cloth, and vacuum the grille gently at low power. Do not use alcohol, ammonia, or abrasive sprays because they can dull the finish or damage the driver.
Does the DX-C390 need a subwoofer?
For music in a small room, the DX-C390 reproduces substantial bass. For movie effects or very low frequencies, adding a subwoofer and setting your receiver to small speaker mode will deliver deeper, more controlled bass.
What type of drivers does the DX-C390 use?
The DX-C390 features a Klipsch horn-loaded tweeter for clear highs and low distortion, paired with a high-performance woofer for dynamic midrange and bass. This combination provides efficient, room-filling sound.
What is the nominal impedance of the DX-C390?
The DX-C390 has a nominal impedance of 8 ohms, making it compatible with most stereo receivers and A/V amplifiers. Always check that the amplifier can drive an 8-ohm load at the volume you use.
Are replacement parts available for the DX-C390?
Yes. Klipsch customer service can supply genuine spare parts such as tweeters, woofers, grilles, and terminal cups. Quote the model number DX-C390 and the serial number on the back of the speaker when ordering.
How long does it take to break in the DX-C390?
Expect 20 to 30 hours of playback at moderate volume for the driver suspension to loosen. During this period, bass becomes deeper and more extended, but you can listen normally from the start.
