Short answer: the Dynamo 1600X for output, the SVS SB-2000 Pro for a sealed 12-inch alternative. The 15-inch Dynamo’s 900W RMS and 1800W peak deliver forceful, clean, tight low bass, but it costs $1,606.77 and its 121.5 dB mid-range output is a caveat. The sealed 12-inch SB-2000 Pro runs 550W RMS and 1500W peak from its Sledge amplifier.
Buy the SVS SB-2000 Pro new; the MartinLogan Dynamo 1600X is no longer sold new, so it only makes sense as a used find.
