Short answer: the JTR Orbit Shifter PRO on output, the Rythmik FV15HP for value. The FV15HP’s 15-inch ported driver reaches 122.0dB CEA-2010-A average, matching subwoofers that cost significantly more, though its ported design depends on room gain and it weighs 114.6 lbs (52 kg). The Orbit Shifter PRO’s dual 18-inch horn-loaded drivers deliver a class-leading 141.3dB, at $4,499 and 185.2 lbs (84 kg).
Buy the JTR Speakers Orbit Shifter PRO. It is rated higher for sound quality, and saving $2,372 with the Rythmik FV15HP does not make up for the sound-quality gap.
