Vue Audiotechnik H-15 vs RCF KX 45-A

Short answer: the KX 45-A if you want RCF’s flagship networked point source, the H-15 if you specifically want its narrower, feedback-resistant pattern. These rank #2 and #3 out of 29 15-inch powered PA speakers, priced at $6500 and $4620.

The H-15 uses a beryllium-diaphragm compression driver and a narrow horn. Low-quality vendor data still returns a strong 5.2 ideal-subwoofer preference score with roughly 70Hz extension, continuing the h-Class’s beryllium-diaphragm compression driver and narrow, feedback-resistant 60° x 40° pattern from the h-12. At 38kg and a $6,500 asking price this is among the heaviest and most expensive 15-inch boxes here, aimed at rental and touring use rather than casual portability, and the low-quality measurement source limits confidence in the exact result.

The KX 45-A has the highest claimed peak output in this entire ranking, plus RDNet control. RCF’s flagship 15-inch point source pairs a 3200W amplifier with a 3-inch titanium-dome compression driver, RDNet remote control and a 137dB claimed peak, the highest maximum-output claim among the 15-inch boxes here. Rotatable 100° x 70° coverage suits both main and monitor use, but the local measurement is truncated and cannot produce a preference score, and at 28.4kg it’s one of the heaviest boxes here as well, with pricing and retail availability not yet well established.

What the H-15 adds:

• A beryllium-diaphragm compression driver, a premium material over the KX 45-A’s titanium dome.
• Ethernet/IP remote monitoring and control, an alternative networking approach to RCF’s RDNet.

What the KX 45-A adds:

• RDNet remote control integrated with RCF’s system ecosystem.
• A significantly higher claimed peak output, 137dB versus the H-15’s 136dB.
• A wider, rotatable 100° x 70° horn, versus the H-15’s fixed 60° x 40°.
• Roughly 10kg less weight at 28.4kg versus the H-15’s 38kg.

Buy the KX 45-A for RCF’s networked ecosystem, the highest claimed output, and meaningfully less weight to carry.

Buy the H-15 if you specifically need its narrow, feedback-resistant pattern and beryllium driver for monitor or stage-fill work.
