Short answer: the RCF ART 935-A, if you are buying new. The LD Systems DDQ15 measures as well as it (#16 vs #17 of 76 15-inch pa speakers, 3.9/5 vs 3.9/5) but is discontinued, so only consider it used; the RCF ART 935-A is still sold new at $1,499.
The DDQ15 backs its engineering with real numbers. Medium-quality vendor data returns a 5.79 ideal-subwoofer preference score, among the best in this ranking, with 42Hz measured extension. Its Faital Pro woofer, BMS compression driver, birch-ply cabinet and biamped Hypex Class-D modules running a 24-bit Sharc DSP represent genuine touring-class engineering. The ART 935-A’s low-quality vendor measurement is truncated and cannot generate a preference score, so its tonal position relies on published engineering and its 12-inch ART 932-A sibling’s reputation rather than a confirmed result.
Coverage and service network cut the other way. The DDQ15’s rotatable HF horn covers 80 degrees x 50 degrees, narrower than the ART 935-A’s 100 x 60 degree pattern, and its own review notes LD Systems has a smaller professional-audio service network than JBL, Yamaha or RCF in North America. The ART 935-A claims a slightly higher 133dB peak and stays manageable at 53.4 lbs (24.2 kg) for a box this size.
Both use large-format compression drivers: the DDQ15 pairs a BMS unit with its Faital woofer, while the ART 935-A carries a bigger-voice-coil driver mirroring the well-regarded ART 932-A’s design.
Buy the LD Systems DDQ15 for the confirmed strong preference score and touring-grade Hypex/Sharc electronics.
Buy the RCF ART 935-A if wider retail and service support matter more than a confirmed measurement, and the broader coverage pattern suits your room.

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.
