Short answer: the Perlisten R5m for better sound quality, the Klipsch RP-600M II for the lower price. The Perlisten R5m ranks #39 of 130 bookshelf speakers at $3295. The Klipsch RP-600M II ranks #74 at $449.99, $2845.01 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 Perlisten R5m offers: The standmount version of Perlisten’s DPC-Array platform (three silk-dome drivers plus dual 6.5” woofers), reaching a measured -6dB point of 50.5Hz. A directivity-index standard deviation of 3.01 is tight for a standmount this size. THX-adjacent R-series build quality at a lower price than Perlisten’s S-series. Watch for: On-axis deviation of 0.264dB and sound-power smoothness of 0.511 are middling, with a fairly pronounced -0.29dB per octave downward tonal tilt and a bass-alignment Q of 2.40 pointing to a somewhat resonant low end. Like the rest of the R-series it’s sold only through specialty AV dealers with per-unit pricing.
