Retain the packaging for future transport or storage.

2. Speaker Placement

Proper speaker placement is crucial for optimal sound performance. Consider the following guidelines:

• Stereo Setup: Place the speakers equidistant from your primary listening position, forming an equilateral triangle.
• Height: Position the tweeters at approximately ear level when seated.
• Distance from Walls: Experiment with placing speakers a few inches to a few feet from walls to adjust bass response. Closer placement generally increases bass.
• Symmetry: Ensure both speakers are placed symmetrically within the room to achieve a balanced soundstage.

3. Connecting Your Speakers

The R-40M speakers are passive and require connection to an amplifier or A/V receiver. Use high-quality speaker wire for the best performance.

1. Identify the positive (+) and negative (-) terminals on both your amplifier/receiver and the R-40M speakers. The positive terminal is typically red, and the negative is black.
2. Strip approximately 1/2 inch (1.25 cm) of insulation from the ends of your speaker wire.
3. Unscrew the binding posts on the back of the speaker.
4. Insert the bare wire or banana plug into the corresponding terminal. Ensure no stray wire strands are touching the opposite terminal, which could cause a short circuit.
5. Tighten the binding posts securely.
6. Connect the other end of the speaker wire to the corresponding terminals on your amplifier/receiver. Ensure positive (+) on the speaker connects to positive (+) on the amplifier, and negative (-) to negative (-). This maintains correct audio phase.

Operating Your Speakers

Once connected, the operation of your R-40M speakers is controlled by your amplifier or A/V receiver. Refer to your amplifier's manual for specific instructions on power, volume, and input selection.

Key Features:

• 90° x 90° Tractrix Horn: This updated horn design provides precise directivity control, ensuring a wide and accurate soundstage with clear high frequencies.
• Linear Travel Suspension (LTS) Aluminum Tweeter: The 1-inch LTS tweeter minimizes distortion, delivering detailed and enhanced high-frequency performance.
• Spun-Copper Thermoformed Crystalline Polymer (TCP) Woofers: The 4-inch TCP woofers, derived from Klipsch's Reference Premiere series, feature steeper cone angling for smoother response and improved accuracy in the mid-range and bass.
• Magnetic Grilles: The speakers come with low-profile magnetic grilles that can be easily removed for a different aesthetic or for cleaning.

Maintenance

To ensure the longevity and optimal performance of your Klipsch R-40M speakers, follow these simple maintenance tips:

• Cleaning Cabinets: Use a dry, soft cloth to wipe down the speaker cabinets. Avoid abrasive cleaners or solvents, as they may damage the finish.
• Cleaning Grilles: The magnetic grilles can be gently removed and dusted with a soft brush or vacuumed with a low-power attachment.
• Dusting Drivers: If the grilles are removed, carefully dust the woofer and tweeter with a soft, dry brush. Avoid touching the speaker cones directly.
• Avoid Direct Sunlight/Heat: Do not expose the speakers to direct sunlight or extreme heat, as this can degrade the cabinet finish and driver materials over time.
