Short answer: choose between the KV2 Audio EX15 and JBL PRX915 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 KV2 Audio EX15. Medium-quality vendor data gives it a 4.83 ideal-subwoofer preference score with 42Hz measured extension, the deepest bass reach of any 15-inch box in this ranking. Its 3-inch-diaphragm compression driver and integrated DSP target vocal clarity and controlled throw.
The case for 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.
Important trade-offs. 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.
Buy the KV2 Audio EX15 when its stated format, coverage, and system features fit the job better.
Buy the JBL PRX915 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.
