Short answer: the Danley Sound Labs DTS10. It ranks #3 of 7 subwoofers at $4400; the Pro Audio Technology LFC-24sm ranks #4 and costs $10000, so there is not much of a tradeoff to weigh.
The case for the Danley Sound Labs DTS10: Dual 12-inch tapped horn design delivers 129.6dB CEA-2010-A average and remains in current production. The catch: Requires external amplifier, extremely heavy at 129 kg, very large cabinet, and specialized tapped-horn design.
Buy the Danley Sound Labs DTS10 if the ranking matters more than the price. Buy the Pro Audio Technology LFC-24sm if the price matters more than the ranking.
