Short answer: the Reaction Audio PV-15X for the higher ranking, the HSU Research VTF-3 MK5 HP for the lower price. The Reaction Audio PV-15X ranks #16 of 97 subwoofers at $1999. The HSU Research VTF-3 MK5 HP ranks #43 at $1099, $900 cheaper.
What the HSU Research VTF-3 MK5 HP gets right: Ported cabinet delivers 121.4dB CEA-2010-A average, one of the best price-to-output ratios in this weight class. The catch: Ported design requires careful room placement, mid-size 39 kg cabinet, and mid-range output.
On the Reaction Audio PV-15X side: 15-inch ported driver delivers 126.2dB CEA-2010-A average from a purpose-built cinema-style cabinet. The tradeoff: Passive design requires a separate external amplifier and weighs 68 kg.
One note: the Reaction Audio PV-15X is discontinued, but it still ranks #16 of 97 subwoofers, ahead of most of what is still sold new, so it is worth considering used.
Buy the HSU Research VTF-3 MK5 HP if the price matters more than the ranking. Buy the Reaction Audio PV-15X if the ranking matters more than the price.
