Short answer: the Danley Sound Labs DTS10. It ranks #14 of 143 subwoofers by sound quality (rated 4.5/5) at $4,400 and is still sold new; the Reaction Audio PV-15X ranks #22 (rated 4.4/5) and is discontinued, so it is only an option used.

Why pick the Reaction Audio PV-15X: A passive 15 inch ported subwoofer in a cinema style cabinet with strong output for home theater use, now discontinued. The catch: Passive design requires a separate external amplifier and weighs 149.9 lbs (68 kg).
The case for the Danley Sound Labs DTS10: A passive tapped horn subwoofer with dual 12 inch drivers and huge output, still in production unlike many of its peers. The catch: Requires external amplifier, extremely heavy at 284.4 lbs (129 kg), very large cabinet, and specialized tapped-horn design.
Buy the Danley Sound Labs DTS10. It is rated higher for sound quality; the Reaction Audio PV-15X is no longer sold new.
