3. Setup

3.1 Speaker Placement

The 3020i speakers are versatile and can be placed on a shelf, stand, or mounted on a wall. For optimal sound performance, consider the following:

• Shelf or Stand Mounting: The speakers are designed with recessed cut-outs and low-profile binding posts, allowing them to be positioned close to a rear wall without compromising sound quality.
• Rubber Speaker Grips: Attach the included rubber speaker grips to the bottom of the speakers to provide stability and minimize vibrations when placed on surfaces.
• Foam Bungs: If the bass response is too prominent due to close proximity to a wall or corner, insert the foam bungs into the rear reflex ports to reduce bass output and achieve a more balanced sound.

3.2 Connecting to Your Amplifier

Ensure your amplifier is turned off before making any connections. The 3020i speakers feature low-profile binding posts that are deep enough to accept 0.16-inch (4mm) banana plugs, as well as bare wire connections.

1. Connect the positive (+) terminal (red) on the speaker to the positive (+) terminal on your amplifier.
2. Connect the negative (-) terminal (black) on the speaker to the negative (-) terminal on your amplifier.
3. Ensure all connections are secure to prevent signal loss or short circuits.

4. Operating the Speakers

Once properly connected to a suitable amplifier, your Q Acoustics 3020i speakers are ready for use. These passive speakers require an external amplifier to produce sound. Refer to your amplifier's manual for specific operating instructions.

• Power Input: The speakers are designed to handle a power input of 50-125W. Ensure your amplifier's output power is within this range to prevent damage.
• Impedance: The nominal impedance is 6 Ohms, with a minimum impedance of 4 Ohms. Verify your amplifier is compatible with these impedance ratings.
• Speaker Grilles: The magnetic speaker grilles can be easily attached or removed. For critical listening, some users prefer to remove the grilles to allow the sound to propagate without obstruction.

5. Maintenance

To ensure the longevity and optimal performance of your Q Acoustics 3020i speakers, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to gently wipe the speaker cabinets. Avoid using abrasive cleaners, solvents, or excessive moisture, as these can damage the finish.
• Handling: When moving the speakers, use the included handling gloves to avoid leaving fingerprints or marks on the surface. Always lift the speakers from the base, not by the drivers or grilles.
• Environment: Place the speakers in a stable environment, away from direct sunlight, excessive heat, humidity, or extreme temperature fluctuations.
• Dust: Regularly dust the speaker grilles and drivers to prevent dust buildup, which can affect sound quality over time.

6. Troubleshooting

If you encounter any issues with your Q Acoustics 3020i speakers, refer to the following common troubleshooting tips:

• No Sound:
  • Check all cable connections between the speakers and the amplifier. Ensure they are secure and correctly connected (positive to positive, negative to negative).
  • Verify the amplifier is powered on and functioning correctly.
  • Ensure the correct input source is selected on your amplifier.
• Distorted Sound:
  • Check for loose speaker wire connections.
  • Ensure the amplifier's volume is not set too high, causing clipping or distortion.
  • Verify the amplifier's power output and impedance match the speaker's specifications.
  • Check if the foam bungs are correctly inserted if bass is boomy.
• Uneven Sound or Imaging:
  • Ensure speakers are placed symmetrically and at an equal distance from the listening position.
  • Check that both speakers are connected with correct polarity.

If the issue persists after attempting these steps, please contact Q Acoustics customer support for further assistance.
