Short answer: choose between the JBL PRX915 and Yamaha DXR15mkIII for the requirements of the venue and system, not from rank alone. In this size class, coverage, bass extension, output capability, DSP, cabinet construction, and service support often decide the better fit.
Why choose the JBL PRX915. High-quality vendor data shows a 4.77 ideal-subwoofer preference score with 51Hz measured extension, backed by JBL’s extensive service network and 12-band parametric EQ with dbx DriveRack feedback suppression carried over from the PRX912.
Why choose the Yamaha DXR15mkIII. The third-generation DXR15 raises claimed output to 134dB with 2000W amplification, app-based control and Yamaha’s newest onboard DSP, while its 90° x 60° pattern matches the well-regarded DXR12mkIII.
What to weigh before buying. Its measured preference trails the 12-inch PRX912, and at 53.1 lbs (24.1 kg) it is meaningfully heavier to carry to a gig than the smaller model. The low-quality local data is truncated and cannot produce a preference score, so its tonal advantage over the proven DXR15mkII is unconfirmed. Wireless connectivity is for remote control, not audio streaming.
Buy the JBL PRX915 when its stated coverage, output, processing, and deployment format best match the job.
Buy the Yamaha DXR15mkIII when its stated strengths are the better match for the room and the rest of the PA.

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.
