Short answer: the Seeburg X4. It ranks #9 of 28 10-inch pa speakers by sound quality, rated 3.9/5, at $1,369. The RCF NX 910-A ranks #22, rated 3.5/5, at $1,349, $20 cheaper, which does not close the gap in sound quality.
The case for the Seeburg X4: Its 6.08 preference score with an ideal subwoofer places it in the upper half of this ranking, and its 1.8dB reference band keeps the midrange and treble tonally even. The catch: Bass drops early, at 95Hz for -3dB and about 70Hz for -10dB, so a subwoofer is needed for full-range music.
Why pick the RCF NX 910-A: The plywood enclosure and FiRPHASE/Bass Motion Control processing make it a sturdier systems alternative to the ART 710-A MK5, with a wide 100° x 60° pattern and 130dB claimed peak. The tradeoff: The truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders.
Buy the Seeburg X4. It is rated higher for sound quality, and saving $20 with the RCF NX 910-A does not make up for the sound-quality gap.

The Two Speakers In Full
Seeburg X4: $1,369 Passive Thomann eBay
Pros: Its 6.08 preference score with an ideal subwoofer places it in the upper half of this ranking, and its 1.8dB reference band keeps the midrange and treble tonally even. The coaxial 10-inch and 1-inch neodymium drivers keep sound consistent as listeners move around, with 0.66 predicted in-room smoothness. At 12.5kg with 97dB sensitivity and a 127dB peak rating, it also works as a stage monitor or pole-mounted top. Measured bass extension of 95Hz (-3dB).
Cons: Bass drops early, at 95Hz for -3dB and about 70Hz for -10dB, so a subwoofer is needed for full-range music. It is passive and needs an external amplifier and processor with Seeburg presets, unless you buy the self-powered X4 dp instead. A 4.26 directivity-index deviation means off-axis tone varies more than the best coaxials here.
