Short answer: choose between the HK Audio LINEAR 7 115 FA and Yamaha DZR15 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 HK Audio LINEAR 7 115 FA. High-quality vendor data returns a 6.03 ideal-subwoofer preference score with 60Hz measured extension. MILAN/AVB networking, a 10-band parametric EQ and a rotatable constant-directivity horn make it a systems-oriented choice for professional deployment.
The case for the Yamaha DZR15. Medium-quality vendor data returns a 5.25 ideal-subwoofer preference score with 39Hz measured extension, deeper than the DZR12. The bi-amped 2-inch compression driver and sophisticated onboard DSP target serious main-speaker duty.
Important trade-offs. At 70.5 lbs (32 kg) this is a heavy 15-inch cabinet, and buyers who do not need networked audio may find comparable performance in simpler mainstream models. The 60° x 40° pattern is narrower than several rivals. The bass-extension figure comes from truncated manufacturer data and should be read cautiously.
Buy the HK Audio LINEAR 7 115 FA when its stated format, coverage, and system features fit the job better.
Buy the Yamaha DZR15 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.
