Short answer: the Radiant Acoustics Clarity 6.2 on measured sound quality, the Klipsch RP-600M II on price. The Radiant Acoustics Clarity 6.2 ranks #27 of 130 bookshelf speakers at $4500. The Klipsch RP-600M II ranks #74 at $449.99, $4050.01 cheaper.
What the Klipsch RP-600M II offers: 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. Watch for: 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.
What the Radiant Acoustics Clarity 6.2 offers: Custom AMT (Air Motion Transformer) tweeter paired with a 6.5” Purifi Eikona midrange and dual Purifi passive radiators in a passive-radiator enclosure, crossed over at 2.4kHz. Rigid cabinet construction (21mm MDF with a 15mm aluminum front baffle, extensive internal bracing) helps keep resonance in check. A deliberately rising on-axis response paired with narrowing directivity above about 2kHz yields a genuinely linear, non-fatiguing in-room sound rather than the “fake detail” of speakers with a straight treble boost. Excellent pair matching between units (within about 1dB), contributing to precise, well-focused imaging that clearly separated fine details in test tracks. In-room bass extension reaches a solid 40Hz with real kick-drum authority, not just sub-bass rumble. Class-leading dynamic range and compression performance - among the best the reviewer has measured at this price point. Watch for: Needs a fairly specific setup to sound its best: about 15-20° of toe-out (per the manufacturer’s own recommendation) and roughly 2 feet from the rear wall; pointed straight on-axis, the treble reads as noticeably elevated. Low impedance (2.1-ohm minimum, about 1-ohm minimum EPDR) demands an amplifier genuinely comfortable with 4-ohm-and-below loads. Soundstage width narrows above about 5kHz, even though the AMT tweeter itself is capable of wider dispersion. An unexplained resonance appears in harmonic distortion measurements on both units tested (though not on the reviewer’s reference speaker) - possibly a basket resonance, and not something the reviewer could hear. A minor bump around 500Hz in the estimated in-room response could add a touch of boxiness for some listeners, though the reviewer didn’t personally notice it. F3 of 55Hz and F10 of 32Hz mean a subwoofer is still needed for home-theater rumble or bass-heavy genres like rap.
