Short answer: the JTR Orbit Shifter PRO on output, the Reaction Audio PV-15X on a cinema-style passive build. The PV-15X’s 15-inch ported driver delivers 126.2dB CEA-2010-A average from a purpose-built cinema cabinet, but as a passive design it needs a separate external amplifier and weighs 68 kg. The Orbit Shifter PRO’s dual 18-inch horn-loaded drivers reach a class-leading 141.3dB, at $4499 and 84 kg.
The case for the JTR Speakers Orbit Shifter PRO: Dual 18-inch horn-loaded drivers deliver a class-leading 141.3dB CEA-2010-A average, well beyond any other subwoofer tested. Set against that: Extremely high price ($4,200) and weighs 84 kg (185.2 lbs) - requires dedicated placement and amplifier.
What the Reaction Audio PV-15X gets right: 15-inch ported driver delivers 126.2dB CEA-2010-A average from a purpose-built cinema-style cabinet. Set against that: Passive design requires a separate external amplifier and weighs 68 kg (149.9 lbs).
One note: the Reaction Audio PV-15X is no longer sold new, but at #21 of 110 subwoofers by sound quality it still outranks most current models, so used is worth considering.
Buy the JTR Speakers Orbit Shifter PRO. It is rated higher for sound quality, and saving $2500 with the Reaction Audio PV-15X does not make up for the sound-quality gap.
