What is the best setting for an SVS subwoofer?

  • Posted on

Optimizing the settings for your SVS subwoofer depends on factors like your room's acoustics, listening preferences, and the configuration of your audio system. Here are some general guidelines to enhance its performance:

  1. Placement
  • Room Corner: Positioning the subwoofer in a corner can maximize output, but be cautious of overly boomy bass.
  • Experiment with Location: Slightly moving the subwoofer within the room can help achieve the best bass response.
  • Sound Optimization: Avoid placing the subwoofer too close to walls to minimize bass reflections.

 

  1. Phase Setting
  • 0° or 180°: This setting ensures the subwoofer operates in sync with your other speakers. Test both settings to determine which provides the tightest and most integrated bass. Play with this setting to bring the sub into better phase with the other speakers (for tighter bass).
  • Variable Phase: For finer control, use the variable phase adjustment in the SVS app to precisely align the subwoofer's output with your main speakers.

 

  1. Crossover Frequency
  • 80 Hz (THX Standard): Ideal for full-range speakers; set the crossover at 80 Hz to let the subwoofer handle low frequencies.
  • Speaker Size Consideration: For smaller satellite speakers, consider a higher crossover setting, such as 100-120 Hz.
  • Low-Frequency Cutoff: If your main speakers produce substantial bass, you might set the crossover lower (60-70 Hz) to prevent overlap.

Set the crossover point

The crossover point determines which frequencies go to the subwoofer and which go to the other speakers

  • Usual crossover value: between 80 Hz and 120 Hz
    • 80 Hz: If you have large floorstanding speakers.
    • 100-120 Hz: If you have smaller bookshelf speakers.

 

  1. Volume
  • Natural Integration: Adjust the subwoofer's volume to blend seamlessly with your system. The bass should be neither overpowering nor subdued.
  • Automatic Calibration: If your AV receiver has an auto-calibration feature like Audyssey, utilize it to set the appropriate volume level.
  • Volume: Turn it up slightly if you want even more bass.

 

  1. Room Gain Compensation
  • SVS App Adjustment: Use the SVS app to modify room gain if the bass is excessively strong due to room acoustics, a common issue in smaller spaces.
  • Room Correction: Address acoustic anomalies in your room by employing the room gain compensation feature to refine frequency response.

 

  1. EQ Settings
  • Customize to Taste: The SVS app offers an equalizer to tailor the bass response to your preferences or to address specific room acoustic challenges.

 

  1. Low Pass Filter (LPF)
  • AV Receiver Management: If your AV receiver manages the low pass filter, disable the subwoofer's internal LPF to avoid redundant filtering, which can degrade sound quality.

Adjust the filter settings correctly

There are often high-pass (HPF) and low-pass filters (LPF) in your amplifier or processor:

  • LPF for subwoofer: Set to e.g. 100 Hz → Subwoofer gets everything below 100 Hz
  • HPF for other speakers: Set to 100 Hz → Other speakers get everything above 100 Hz
This way you avoid overlap and you send the layer to the sub.

 

By implementing these strategies, you can achieve optimal bass performance with your SVS subwoofer. Remember, fine-tuning based on your specific environment and listening habits is key to the best sound experience.
