  • Linear Response Waveguide: This waveguide ensures smooth and even dispersion of high frequencies, creating a wider sweet spot and reducing unwanted reflections. The waveguide helps to create a more natural and lifelike listening experience.
  • Advanced Crossover Network: The crossover network precisely divides the audio signal between the various drivers, ensuring seamless integration and optimal performance. This network is carefully designed to minimize distortion and maximize clarity.

Understanding these features is essential for properly setting up and optimizing your D15 speakers. By knowing how each component contributes to the overall sound, you can make informed decisions about placement, calibration, and equalization.

Setting Up Your Definitive Technology D15 Speakers

Proper setup is crucial for achieving optimal performance from your Definitive Technology D15 speakers. Here's a step-by-step guide to help you get started:

  1. Placement: The placement of your speakers significantly impacts the sound quality. Experiment with different positions to find the optimal location in your room. As a general rule, position the speakers at least 6-8 feet apart and angled slightly inward towards the listening position. Keep them away from walls to avoid excessive bass buildup. The bipolar design of the D15s means that wall reflections are part of the design, but too close can lead to a boomy sound.
  2. Connections: Connect the speakers to your amplifier or receiver using high-quality speaker cables. Ensure that the polarity is correct, connecting the positive (+) terminal on the amplifier to the positive (+) terminal on the speaker, and the negative (-) terminal on the amplifier to the negative (-) terminal on the speaker. Incorrect polarity can result in a thin and weak sound.
  3. Power Cord: Connect the power cord to the D15's built-in subwoofer amplifier. Make sure the voltage matches your local power supply.
  4. Subwoofer Level Adjustment: Adjust the subwoofer level using the control knob on the back of the speaker. Start with a low setting and gradually increase the level until the bass is balanced with the rest of the audio. Avoid setting the level too high, as this can result in a muddy and overpowering bass response.
  5. Break-In Period: Like all new speakers, the D15s require a break-in period for the drivers to loosen up and reach their full potential. Play music at moderate levels for several hours to allow the speakers to break in properly. You'll notice a gradual improvement in sound quality over time.

Optimizing Speaker Placement for Your Room

Speaker placement is not a one-size-fits-all solution. The optimal placement depends on the size and shape of your room, as well as the acoustic properties of the surfaces. Here are some tips for optimizing speaker placement in your listening environment:

  • The Equal Triangle: Aim for an equilateral triangle between your speakers and your listening position. This means that the distance between the speakers should be approximately the same as the distance from each speaker to your listening position.
  • Toe-In: Experiment with different amounts of toe-in, which is the angle at which the speakers are pointed towards the listening position. More toe-in will result in a more focused and precise soundstage, while less toe-in will create a wider and more spacious soundstage.
  • Room Acoustics: Consider the acoustic properties of your room. Hard surfaces like walls and floors can reflect sound, creating echoes and reverberations. Soft surfaces like carpets and curtains can absorb sound, reducing reflections and improving clarity. Experiment with adding acoustic treatments to your room to optimize the sound quality.
  • Subwoofer Placement: If you're using a separate subwoofer, experiment with different placement options to find the location that provides the most balanced and impactful bass response. Corner placement will typically result in the loudest bass, but it can also be the most uneven. Try placing the subwoofer along a wall or in the front of the room for a more balanced sound.

Calibrating Your Definitive Technology D15 Speakers

Calibration is the process of adjusting the settings on your speakers and amplifier to optimize the sound quality for your specific listening environment. Here are some tips for calibrating your Definitive Technology D15 speakers:

  • Level Matching: Use a sound level meter to match the output levels of all your speakers. This ensures that each speaker is playing at the same volume, creating a balanced and cohesive soundstage.
  • Distance Compensation: Adjust the distance settings on your amplifier or receiver to compensate for the distance between each speaker and your listening position. This ensures that the sound from each speaker arrives at your ears at the same time, creating a more accurate and realistic soundstage.
  • Crossover Settings: Set the crossover frequency for your subwoofer to blend seamlessly with the main speakers. The optimal crossover frequency will depend on the size and capabilities of your main speakers.
  • Equalization: Use an equalizer to adjust the frequency response of your speakers to compensate for any acoustic anomalies in your room. This can help to reduce unwanted peaks and dips in the frequency response, resulting in a more balanced and natural sound.

Using Room Correction Software

Many modern amplifiers and receivers include built-in room correction software that can automatically calibrate your speakers for your specific listening environment. These systems use a microphone to measure the acoustic response of your room and then automatically adjust the settings on your amplifier to compensate for any anomalies. Popular room correction systems include Audyssey, Dirac Live, and ARC (Anthem Room Correction). These systems can be a valuable tool for optimizing the sound quality of your Definitive Technology D15 speakers, especially in challenging acoustic environments.

Troubleshooting Common Issues

Even with proper setup and calibration, you may occasionally encounter issues with your Definitive Technology D15 speakers. Here are some common problems and their solutions:

  • No Sound: Check the speaker connections and ensure that the amplifier is turned on and set to the correct input. Verify that the volume is turned up and that the speakers are not muted. If you're using a separate amplifier, make sure it's properly connected to the receiver or source device.
  • Distorted Sound: Reduce the volume level to see if the distortion disappears. Check the speaker connections to ensure that they are secure and that the polarity is correct. If the distortion persists, there may be a problem with the speakers or the amplifier.
  • Weak Bass: Check the subwoofer level and ensure that it is properly adjusted. Verify that the subwoofer is turned on and that the power cord is connected. Experiment with different subwoofer placement options to find the location that provides the most balanced bass response.
  • Hum or Buzz: Check the speaker connections and ensure that they are properly grounded. Try using a different power outlet or a power conditioner to eliminate any ground loops. If the hum or buzz persists, there may be a problem with the speakers or the amplifier.
