Sealed vs Ported: Which Subwoofer Box Is Better?
Your box choice changes how your subwoofer sounds more than most people realize. Sealed boxes are tighter and cleaner. Ported boxes are louder and more aggressive. The right one depends on your goals, space, and music.
Sealed Box
Best if you want tight, accurate, musical bass, smaller box size, and easier setup.
Ported Box
Best if you want more output, more efficiency, and harder-hitting bass for bass-heavy music.
