Short answer: choose between the LD Systems DDQ10 and HK Audio LINEAR 9 110 XA 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 LD Systems DDQ10. Medium-quality vendor data returns a 6.83 ideal-subwoofer preference score, the second-strongest result in this ranking, with 63Hz measured extension. A Faital Pro woofer, BMS compression driver and biamped Class-D amplification carry over the DDQ12/DDQ15’s touring-class engineering into a compact 10-inch cabinet.
The case for the HK Audio LINEAR 9 110 XA. High-quality vendor data returns a 6.34 ideal-subwoofer preference score with 75Hz measured extension, matching the LINEAR 7 110 XA’s result. MILAN networking and comprehensive remote DSP make it a strong systems-oriented choice for professional deployment.
Important trade-offs. LD Systems has a smaller professional-audio service network in North America than JBL, Yamaha or QSC. Buyers who do not need networked audio may find better value in simpler mainstream 10-inch models, and its 129dB peak claim is unremarkable for the category.
Buy the LD Systems DDQ10 when its stated format, coverage, and system features fit the job better.
Buy the HK Audio LINEAR 9 110 XA 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.
