Short answer: choose between the QSC K8.2 and Yamaha DBR15 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 QSC K8.2. This is the standout measured result in this ranking: low-quality vendor data still returns a 7.74 ideal-subwoofer preference score, continuing the K.2 series’ strong showing at every driver size. Extensive onboard DSP, a titanium compression driver and QSC’s long market track record make it an unusually safe general-purpose 8-inch pick.
The case for the Yamaha DBR15. Yamaha’s most portable 15-inch powered speaker carries the same DSP and amplification platform as the DXR and DZR series, with a built-in 2-channel mixer accepting XLR, 1/4-inch, RCA and 3.5mm sources.
Important trade-offs. The underlying Spinorama source is low quality, so its apparent measured lead deserves some caution. An 8-inch woofer means a subwoofer partner matters even more than with the larger K.2 models. Medium-quality vendor data shows a 2.87 ideal-subwoofer preference score, one of the weaker results in this ranking and well below the DBR12’s own measured result, so a subwoofer partner matters more here than with most alternatives.
Buy the QSC K8.2 when its stated format, coverage, and system features fit the job better.
Buy the Yamaha DBR15 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.
