Short answer: choose between the HK Audio LINEAR 7 112 FA and LD Systems DDQ12 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 7 112 FA. High-quality manufacturer data yields a respectable 6.45 ideal-subwoofer preference score, and the networkable DSP is useful in larger systems. The 112 FA is designed as a full-range cabinet rather than the more monitor-focused XA variant.
The case for the LD Systems DDQ12. Medium-quality vendor data returns a strong 6.32 ideal-subwoofer preference score and 63Hz bass extension. The lightweight 37.5 lbs (17 kg) plywood enclosure and controlled 80° x 50° horn make it easy to deploy as a compact professional top.
Important trade-offs. Measured bass extension is 63Hz and the value proposition depends on needing its system networking and professional rigging features. US availability is less consistent than QSC, JBL, Yamaha or RCF. The discontinued DDQ platform is harder to buy and support than current LD, RCF, JBL or Yamaha ranges. Its controls and connectivity are basic by modern standards, with no app, networking or onboard mixer.
Buy the HK Audio LINEAR 7 112 FA when its stated format, coverage, and system features fit the job better.
Buy the LD Systems DDQ12 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.
