Short answer: the Monoprice Monolith M-10 V2 for deep ported output, the Rythmik F12 for a sealed servo design. The M-10 V2 reaches 17-20Hz from a 10-inch THX-certified ported cabinet with 500W RMS and costs $685.03 less. The F12 is a sealed 12-inch servo sub with 370W RMS that the notes call excellent value.
