Looking at overall performance dimensions: The Rythmik Audio G25HP leads in value, form factor, room fit. They score similarly in audio quality, volume/SPL.
Key subwoofer differences include driver sizes of 21" vs 15", and bass-reflex vs sealed enclosure designs, and the Power Sound Audio TV21-IPAL digs deeper at 12 Hz (-3dB) vs 14 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.
