Short answer: choose between the PreSonus ULT12 and RCF ART 945-A 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 PreSonus ULT12. Very broad 110° x 50° nominal coverage can be useful in shallow rooms, and the plywood cabinet, rotatable horn and onboard mixer are practical live-sound features. Measured bass extension reaches 60Hz in the medium-quality vendor data.
The case for the RCF ART 945-A. This is the strongest-measuring 15-inch RCF here: medium-quality vendor data produces a 5.91 ideal-subwoofer preference score with roughly 50Hz extension. The top-tier compression driver and 18.8kg enclosure combine unusually high output with easy portability for a 15-inch box.
Important trade-offs. The 2.75 ideal-subwoofer preference score is the weakest in this 15-model group, reflecting major response/directivity irregularity. Pricing and wide retail distribution are not yet well established for this model, and the RCF ART9 range above the 912/932-A pair has a shorter market track record. Coverage and full connector details were not confirmed in local data.
Buy the PreSonus ULT12 when its stated format, coverage, and system features fit the job better.
Buy the RCF ART 945-A when its stated output, control, and deployment strengths better match the system.
Skip the PreSonus ULT12 if sound quality matters to you. It ranks near the bottom of the 37 12-inch two-way powered pa speakers.

Pros: Very broad 110° x 50° nominal coverage can be useful in shallow rooms, and the plywood cabinet, rotatable horn and onboard mixer are practical live-sound features. Measured bass extension reaches 60Hz in the medium-quality vendor data.
Cons: The 2.75 ideal-subwoofer preference score is the weakest in this 15-model group, reflecting major response/directivity irregularity. It is difficult to recommend for sound quality when stronger measured alternatives are available at similar prices.
