When it may not be suitable

How to use
To set up the SONAR 115 SUB D, place the unit on a stable, flat surface. Connect your audio source or mixer output to the subwoofer's input using high-quality XLR cables. If you are using SONAR series full-range speakers, utilize the integrated crossover settings within the DSP to ensure a smooth frequency transition between the subwoofer and the top cabinets. Adjust the volume and DSP settings via the rear-panel interface to match your specific venue requirements and personal sound preferences.
What to consider before purchase
Ensure you have sufficient transport space for a 15-inch subwoofer unit.
Verify that your existing audio system components are compatible with the subwoofer's input/output configuration.
Consider the size of your venue to determine if a single or dual subwoofer setup is necessary for adequate coverage.
Usage recommendations
For optimal performance, always ensure the subwoofer is placed on a solid floor to minimize unwanted vibrations. Regularly check all cable connections before events and utilize the built-in DSP presets to quickly adapt the sound profile to different room acoustics.
