Short answer: the Infinity Reference R162, because the Klipsch RP-600M II needs work to sound balanced. The Klipsch’s redesigned waveguide sits flush to the baffle edge to cut diffraction, but its on-axis treble runs notably hot, even hotter than the original in some respects, and it needs about 20 degrees of toe-out or the grille. The R162 has wide, consistent directivity with a resonance around 700Hz.
Buy the Klipsch RP-600M II if you want one new; the Infinity Reference R162 is discontinued, so only look for it used.

Infinity Reference R162: $500 per pair Discontinued eBay
Pros: CEA2034 spinorama shows good directivity with wide, consistent horizontal and vertical response, and blended early reflections that need little room treatment. 1” CMMD waveguide tweeter and 6.5” CMMD woofer, 85.5dB sensitivity. Measured bass extension of 67.4Hz (-3dB), with a measured sensitivity of 87dB.
Cons: Elevated output above 3kHz adds brightness, with a resonance around 700Hz and some distortion near the crossover point. EQ or a simple inline tweeter resistor can tame the treble; the reviewer still called it a very enjoyable system for the price. Discontinued.

Klipsch RP-600M II: $449.99 per pair Amazon eBay
Older model: the Klipsch RP-600M (ranked lower, rated 2.9/5).
Pros: Redesigned waveguide extends flush to the baffle edge, reducing diffraction compared to the original RP-600M. Roughly 10-20° wider horizontal radiation than the original, giving more soundstage envelopment while retaining precise imaging. A major step up in overall tonal neutrality compared to the original RP-600M, largely eliminating that model’s midrange resonance issues. Unusually, sounds better with the grille on: the grille smooths out the elevated treble rather than degrading the sound, a rare trait among speakers the reviewer has tested. More refined back-panel hardware, including anodized binding posts and jumper cables for optional bi-amping. Responds well to EQ correction (verified using measurement software and a miniDSP), letting the on-axis response be made genuinely linear. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 86dB.
Cons: On-axis, the treble runs notably hot (even hotter than the original RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced. Horizontal dispersion is very slightly less linear across angles than the original RP-600M, a minor trade-off for the wider overall radiation pattern. Klipsch’s marketed sensitivity (about 94.5dB) is, like the original, a half-space rating roughly 9dB above the anechoic reality (closer to 85-86dB). In-room bass rolls off around 60Hz in practice, and a 120Hz boost paired with a midrange scoop gives kick drums their “tambour” without real low-end weight: a subwoofer is still recommended. Vertical listening tolerance is limited to about ±10° from the tweeter axis. Toeing the speaker out for better on-axis tonality (rather than using the grille) introduces slightly more diffuse imaging from added sidewall reflections.
