Short answer: the LD Systems DDQ15 for the confirmed measured performance. These rank #9 and #10 out of 29 15-inch powered PA speakers, separated by a $301 price gap.
The DDQ15 backs its engineering with real numbers. Medium-quality vendor data returns a 4.98 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 24.2kg 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.

The Two Speakers In Full
LD Systems DDQ15: $1,800.00 eBay
Pros: 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.
Cons: 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.
