Looking at overall performance dimensions: The KEF KC92-WHITE-GLOSS scores higher in audio quality, volume/SPL, form factor, room fit. They score similarly in value.
Key subwoofer differences include driver sizes of 9" vs 10", and sealed vs ported enclosure designs, and the KEF KC92-WHITE-GLOSS digs deeper at 11 Hz (-3dB) vs 27 Hz. Larger drivers move more air, producing deeper bass with less effort. A 15-inch driver reaches lower than a 10-inch at the same power, but the cabinet is proportionally larger. Sealed subs are tighter and more accurate, better for music. Ported subs play louder and dig deeper for the same driver/amp, better for movies. Some subs offer both via a removable port plug. A lower number means deeper bass — the rumble in explosions, the weight of a pipe organ. Below 20 Hz you feel it more than hear it.
