The Two Speakers In Full
Genelec 7370A: $4,195 B&H Photo Video eBay
Older model: the Genelec 7070A (rated 3.6/5).
Pros: 12-inch (305mm) driver with a 400W Class D amplifier. Genelec rates it at 19-100Hz within 3dB and at least 113dB short-term maximum output. Analog and AES/EBU digital XLR inputs and outputs, and GLM network control with AutoCal 2 room calibration.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. Room calibration needs Genelec’s GLM kit or 9320A controller, sold separately, and at 48kg it is heavy for its size.

JTR Speakers Orbit Shifter PRO: $4,200 JTR Speakers eBay
Pros: Dual 18-inch horn-loaded drivers deliver a class-leading 141.3dB CEA-2010-A average, well beyond any other subwoofer tested. Built for dedicated home theaters chasing reference-level output rather than living-room duty.
Cons: Extremely high price ($4499) and weighs 84 kg: requires dedicated placement and amplifier.
Notes: Looks like “PA sub”
