Short answer: choose between the LD Systems Stinger 15-A-G3 and FBT J15A 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 LD Systems Stinger 15-A-G3 is the more accurate, deeper-bass option. An affordable powered 15 inch PA speaker with two mic/line inputs and unusually deep bass reach for its price class. Its measured preference score, a predictor of how neutral it sounds, is 2.20 against 1.16 for the FBT J15A. Its bass reaches about 41.2Hz before falling 3dB, against 63Hz for the FBT J15A. It has a microphone input for karaoke or announcements, which the FBT J15A lacks. The catch: The measured preference score is modest, and its 90° x 50° horn is narrower than several higher-scoring competitors.
The case for the FBT J15A. Medium-quality vendor data shows a 3.87 ideal-subwoofer preference score with 61Hz measured extension, extending the compact, wedge-capable J-series design used by the J12A and J8A to a 15-inch woofer.
Important trade-offs. The measured preference score is modest, and its 90° x 50° horn is narrower than several higher-scoring competitors. At 59.1 lbs (26.8 kg) it is one of the heavier budget-tier boxes here. The preference score is on the lower end for this ranking, and detailed coverage, SPL and weight figures were not confirmed in local data.
Buy the LD Systems Stinger 15-A-G3 when its stated format, coverage, and system features fit the job better.
Buy the FBT J15A 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.
