Looking at overall performance dimensions: The Definitive Technology DESCEND DN8-MIDNIGHT-BLACK scores higher in value, form factor, room fit. The MartinLogan DYNAMO-FOUNDATION-12 leads in audio quality, volume/SPL.
Key subwoofer differences include driver sizes of 8" vs 12", and ported vs sealed enclosure designs, and the MartinLogan DYNAMO-FOUNDATION-12 digs deeper at 24 Hz (-3dB) vs 35 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.
