Short answer: the Klipsch RP-500M II. It ranks #7 of 21 bookshelf speakers at $389.99; the JBL Studio 530 ranks #8 and costs $399, so there is not much of a tradeoff to weigh.
What the JBL Studio 530 gets right: CEA2034 spinorama shows a fairly flat on-axis response. Set against that: A peak around 1.4kHz is attributed to a tweeter resonance.
On the Klipsch RP-500M II side: Major mid-range clarity improvement over the original RP-500M: about a 5dB fill-in between 1-3kHz in the estimated in-room response. The tradeoff: Klipsch’s quoted sensitivity (around 92-93dB) uses an unconventional in-room-based rating rather than the standard anechoic measurement.
One note: the JBL Studio 530 is discontinued, but it still ranks #8 of 21 bookshelf speakers, ahead of most of what is still sold new, so it is worth considering used.
Buy the JBL Studio 530 if the price matters more than the ranking. Buy the Klipsch RP-500M II if the ranking matters more than the price.

JBL Studio 530: $399 Discontinued
Pros: CEA2034 spinorama shows a fairly flat on-axis response. Predicted in-room response is very smooth aside from the high-frequency roll-off.
Cons: A peak around 1.4kHz is attributed to a tweeter resonance, and shows up as a distinct spike in harmonic distortion at that frequency along with a second resonance-driven bump around 2kHz. Response rolls off in the high frequencies and the tuning is a bit bass-shy overall. Cumulative spectral decay (waterfall) shows the same 1kHz-region resonances lingering in time. Discontinued.

Klipsch RP-500M II: $389.99 Amazon
Pros: Major mid-range clarity improvement over the original RP-500M: about a 5dB fill-in between 1-3kHz in the estimated in-room response, giving a noticeably more resolved, detailed midrange. More neutral and linear overall than its sibling RP-600M II, which carries about 2-3dB more high-frequency energy and a touch more bass but less overall balance. Very precise soundstage imaging and instrument placement. Distortion through the midrange is cleaner than the previous generation.
Cons: Klipsch’s quoted sensitivity (around 92-93dB) uses an unconventional in-room-based rating rather than the standard anechoic measurement; on an anechoic basis it measures closer to about 85dB, in line with typical bookshelf speakers this size, so it isn’t the outlier in efficiency the spec sheet implies. Horizontal dispersion of about ±40-50° is narrower and more directive than the reviewer’s preference for a wider, more enveloping soundstage. Toeing the speaker out to widen the soundstage or soften on-axis brightness comes at some cost to imaging precision. Slightly less clean in the tweeter region than the midrange, likely tied to crossover placement, though not considered a dealbreaker. Low-frequency output is limited - measured around 95dB at 4 meters for the pair before the woofers started to unload, so a subwoofer is recommended for anyone wanting real bass rather than stepping up to a larger model.
