Short answer: the Seeburg X4. It ranks #9 of 42 10-inch pa speakers by sound quality, rated 3.9/5, at $1,369. The RCF NX 910-A ranks #29, rated 3.5/5, at $1,349, $20 cheaper, which does not close the gap in sound quality.
The Seeburg X4 is the better-sounding pick. A compact passive coaxial 10 inch PA speaker with smooth, consistent sound that works as a stage monitor or pole mounted top. The tradeoff: Bass drops early, at 95Hz for -3dB and about 70Hz for -10dB, so a subwoofer is needed for full-range music.
The RCF NX 910-A is the deeper-bass choice. A sturdy plywood 10 inch powered PA speaker with wide coverage and strong output, built for professional systems. Its bass reaches about 69Hz before falling 3dB, against 95Hz for the Seeburg X4. The catch: 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.
