Short answer: choose between the Vue Audiotechnik H-15 and RCF NX 945-A for the deployment, not from the automatic ranking alone. Their driver format, power requirements, coverage, bass reach, output capability, and control features determine which is the more practical PA for a particular room or system.
The case for the Vue Audiotechnik H-15. Low-quality vendor data still returns a strong 5.2 ideal-subwoofer preference score with roughly 70Hz extension, continuing the h-Class’s beryllium-diaphragm compression driver and narrow, feedback-resistant 60° x 40° pattern from the h-12.
The case for the RCF NX 945-A. The top NX-series 15-inch box pairs a plywood cabinet with a 135dB claimed peak, the highest in the NX range, and a wide 100° x 70° pattern. RCF’s FiRPHASE and Bass Motion Control processing carry over from the smaller NX models.
Important trade-offs. The low-quality measurement source limits confidence in the exact result. The measurement is truncated and does not produce a preference score, so its tonal position relies on published engineering rather than a confirmed result. At 60.2 lbs (27.3 kg) it is heavier than the ART 945-A alternative.
Buy the Vue Audiotechnik H-15 when its stated format, coverage, and system features fit the job better.
Buy the RCF NX 945-A when its stated output, control, and deployment strengths better match the system.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
