Mackie Thump18S v4 18" 1400W Powered Subwoofer

The 18" sub in Mackie's Thump v4 line: 1400 W into an 18" woofer, 132 dB of maximum SPL, and extension down to 25 Hz — the octave a DJ rig or a kick drum actually lives in. The selectable high-pass modes send a matching Thump top (or any powered speaker) just the frequencies it should handle, a phase switch sorts placement problems, and the pole mount puts the top box at head height over it.
