Setup

Speaker Placement

Optimal speaker placement is crucial for achieving the best sound quality. For floorstanding speakers like the Aurora 700, consider the following:

• Distance from Walls: Position the speakers a reasonable distance from the rear and side walls to prevent excessive bass buildup and improve soundstage depth. Experiment with distances to find the best balance for your room.
• Listening Triangle: Aim for an equilateral triangle between the two speakers and your primary listening position. This helps create a focused and immersive stereo image.
• Toe-in: Slightly angle the speakers inward towards the listening position (toe-in) to optimize the soundstage and imaging. Adjust gradually until the sound is most coherent.

Connecting to an Amplifier

The HECO Aurora 700 speakers feature robust binding posts for secure connection to your amplifier. Ensure your amplifier is turned off before making any connections.

1. Speaker Wire Preparation: Strip approximately 1/2 inch (1.2 cm) of insulation from the ends of your speaker wires. Twist the bare strands tightly.
2. Polarity: Connect the positive (+) terminal (red) on the speaker to the positive (+) terminal on your amplifier. Connect the negative (-) terminal (black) on the speaker to the negative (-) terminal on your amplifier. Maintain consistent polarity for both speakers.
3. Bi-wiring/Bi-amping (Optional): The Aurora 700 supports bi-wiring or bi-amping. If you choose not to bi-wire/bi-amp, ensure the metal jumpers connecting the high-pass and low-pass terminals are securely in place. For bi-wiring/bi-amping, remove the jumpers and connect separate speaker cables to the high-pass (tweeter/midrange) and low-pass (woofer) terminals from your compatible amplifier.

Operating

Initial Playback and Break-in

Like many high-fidelity speakers, the HECO Aurora 700 may benefit from a break-in period. During the first 50-100 hours of use, play a variety of music at moderate listening levels. This allows the driver surrounds and suspensions to loosen up, leading to improved bass response and overall sound clarity.

Volume Control

Always adjust the volume using your amplifier or source component. Avoid setting the amplifier volume to excessively high levels, which can lead to distortion and potential damage to the speakers or amplifier.

Maintenance

Cleaning

To maintain the appearance of your speakers, regularly dust the cabinets with a soft, dry cloth. For stubborn marks, a slightly damp cloth can be used, followed immediately by a dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish.

Driver Care

Avoid touching the speaker drivers (woofers, midrange, tweeter) directly, as oils from your skin can attract dust and potentially affect performance. If the grilles are removed, handle the speakers with care.

Troubleshooting

If you experience issues with your HECO Aurora 700 speakers, consult the following common troubleshooting steps:

• No Sound:
  • Ensure the amplifier is powered on and the correct input source is selected.
  • Check all speaker wire connections at both the amplifier and the speakers for secure contact and correct polarity.
  • Verify that the volume is not muted or set too low.
• Distorted Sound:
  • Reduce the volume level on your amplifier.
  • Check speaker wire connections for any loose strands that might be shorting.
  • Ensure your amplifier is not overdriven or clipping.
• Weak or Boomy Bass:
  • Adjust speaker placement relative to walls (moving them further from walls can reduce boominess; closer can increase bass).
  • Check amplifier bass/tone controls or EQ settings.
  • Ensure the room acoustics are not excessively absorbing or reflecting bass frequencies.
• Poor Imaging or Soundstage:
  • Verify speaker placement and toe-in as described in the Setup section.
  • Ensure both speakers are connected with correct polarity.
