Short answer: the JTR Speakers Orbit Shifter PRO. It ranks #1 of 97 subwoofers at $4200; the Power Sound Audio (PSA) TRIAX ranks #3 and costs $7995, so there is not much of a tradeoff to weigh.
On the JTR Speakers Orbit Shifter PRO side: Dual 18-inch horn-loaded drivers deliver a class-leading 141.3dB CEA-2010-A average, well beyond any other subwoofer tested. The catch: Extremely high price ($4,200) and weighs 84 kg - requires dedicated placement and amplifier.
Buy the JTR Speakers Orbit Shifter PRO if the ranking matters more than the price. Buy the Power Sound Audio (PSA) TRIAX if the price matters more than the ranking.
