#51 RCF ART 735-A MK4: $888.00 Discontinued eBay
Newer model: the RCF ART 735-A MK5, ranked higher, estimated 3.4/5, released Jan 2024. See every RCF ART 7 generation.
Pros: A discontinued powered 15 inch PA speaker with strong vocal headroom and decent bass reach in a manageable cabinet. Its large 3-inch compression-driver voice coil, 132dB claimed peak and roughly 53Hz measured extension give it useful vocal headroom and bass reach. The 21.4kg enclosure remains manageable for a 15-inch box. Measured bass extension of 53Hz (-3dB).
Cons: The low-quality vendor data is truncated and does not yield a preference score. It is discontinued and eclipsed by current 9-series and MK5 models.

Frequency Response
How the RCF ART 735-A MK4 measures across the audible range. A flatter listening window (the sound arriving straight at you) is more neutral: peaks sound forward or harsh, dips sound recessed. The estimated in-room response adds what a typical room does, and there a gentle, even tilt down toward the treble is ideal. Both curves are shifted so their 300 Hz to 3 kHz average sits at 0 dB.
Measurement data: spinorama.org, measured by the manufacturer.
EQ for a Neutral Response
No EQ preset: the best simple EQ we can fit to these measurements improves the predicted preference score by less than 0.2. The listening window is already close to flat, and what holds the score back, such as narrow ripple in the response or uneven output off-axis, is not something EQ can fix without making it worse elsewhere.
