Short answer: the ED150A for its confirmed measured result, the ART 935-A if RCF’s design lineage and broader dealer network matter more to you. These rank #17 and #18 out of 76 15-inch powered PA speakers, priced at $1,499 and $1,990, a $491 difference.
The ED150A has a documented, high-quality measurement behind it. High-quality vendor data returns a 5.36 ideal-subwoofer preference score with 47Hz measured extension, matching the well-regarded ED120A’s asymmetric-coverage design in a 15-inch cabinet. Axiom has a much smaller North American dealer and service network than JBL, Yamaha or QSC, though, and detailed coverage and weight figures weren’t confirmed in local data.
The ART 935-A mirrors its respected 12-inch sibling but lacks a confirmed score. The bigger-voice-coil compression driver, 133dB claimed peak and broad 100° x 60° coverage mirror the well-regarded ART 932-A’s design in a 15-inch cabinet, and at 54.2 lbs (24.6 kg) it stays manageable for a box this size. The low-quality vendor measurement is truncated and cannot generate a preference score, so its tonal position relies on published engineering and its 12-inch sibling’s reputation rather than a confirmed result.
Buy the ED150A for the confirmed high-quality measurement and its documented 47Hz bass extension.
Buy the ART 935-A if you want RCF’s broader dealer and service network and are comfortable relying on its 12-inch sibling’s track record rather than a confirmed measurement of this specific model.

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.
