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 4.22 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 4.02 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 24.1kg 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.

KV2 Audio EX15: $6,000.00 eBay
Pros: Medium-quality vendor data gives it a 4.22 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.
Cons: At a roughly $6,000 asking price this specialist box is far less accessible than the mainstream leaders, and user controls are comparatively spare without an onboard mixer or app control.
