The Sound Pressure League Finals wrapped up its 2026 season with several teams posting personal-best burp scores. Multiple top finishers credited gains to enclosure tuning focused on managing port air velocity rather than simply adding power.
Judges noted that the highest-scoring vehicles weren't necessarily running the most power — several mid-power entries outscored higher-power competitors by tightening box volume and tuning frequency to better match their subwoofer's Fs and Xmax specifications.
For competitors building toward next season, the recurring lesson from this year's results is the same one judges have emphasized before: a well-matched box-to-driver pairing on paper still needs to be verified with a real impedance and output sweep before competition day.
