Short answer: choose between the Yamaha DZR15 and LD Systems DDQ15 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 Yamaha DZR15. Medium-quality vendor data returns a 4.54 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.
The case for the LD Systems DDQ15. Medium-quality vendor data returns a 4.98 ideal-subwoofer preference score, among the best in this ranking, with 42Hz measured extension. A Faital Pro woofer, BMS compression driver, birch-ply cabinet and biamped Hypex Class-D modules with a 24-bit Sharc DSP give it genuine touring-class engineering.
Important trade-offs. The bass-extension figure comes from truncated manufacturer data and should be read cautiously. LD Systems has a smaller professional-audio service network than JBL, Yamaha or RCF in North America, and the rotatable HF horn’s 80° x 50° pattern is on the narrower side for wide-audience main use.
Buy the Yamaha DZR15 when its stated format, coverage, and system features fit the job better.
Buy the LD Systems DDQ15 when its stated output, control, and deployment strengths better match the system.

Yamaha DZR15: $1,291.99 Amazon B&H Photo Video Guitar Center eBay
Pros: Medium-quality vendor data returns a 4.54 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.
Cons: The bass-extension figure comes from truncated manufacturer data and should be read cautiously. It lacks Bluetooth audio and app control, and at this price competes with systems-grade alternatives from RCF and HK Audio.
