Short answer: the Danley Sound Labs DTS10. It ranks #3 of 7 subwoofers at $4400; the JBL 4645C ranks #5 and costs $4999, so there is not much of a tradeoff to weigh.
On the Danley Sound Labs DTS10 side: Dual 12-inch tapped horn design delivers 129.6dB CEA-2010-A average and remains in current production. The tradeoff: 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 JBL 4645C if the price matters more than the ranking.
