Short answer: the Dynamo 1600X for power, the SVS PB-1000 PRO for deep ported extension. The sealed 15-inch Dynamo brings 900W RMS and 1800W peak for forceful, clean, tight low bass, though its 121.5 dB mid-range output and $1,606.77 price are the tradeoffs. The 12-inch ported PB-1000 PRO uses 325W RMS to reach a guttural 17Hz low extension.
Buy the SVS PB-1000 PRO, since the MartinLogan Dynamo 1600X is discontinued and only worth hunting down used.
