Short answer: choose between the LD Systems DDQ12 and FBT J12A 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 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.
The case for the FBT J12A. A light, affordable cabinet with medium-quality vendor Spinorama coverage and 54Hz measured bass extension. Its simple mixer and monitor angle suit small bands, speech systems and rehearsal spaces that value portability.
Important trade-offs. 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. The 5.20 ideal-subwoofer preference score and uneven supplied response keep it below the more refined choices. Output, processing and cabinet construction are oriented toward value rather than demanding touring use.
Buy the LD Systems DDQ12 when its stated format, coverage, and system features fit the job better.
Buy the FBT J12A 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.
