Short answer: the ELAC Uni-Fi Reference UBR62 for better sound quality, the Klipsch RP-600M II for the lower price. The ELAC Uni-Fi Reference UBR62 ranks #45 of 105 bookshelf speakers at $1199. The Klipsch RP-600M II ranks #58 at $489.99, $709.01 cheaper.
What the ELAC Uni-Fi Reference UBR62 offers: True three-way stand-mount using a 1-inch tweeter concentrically mounted in a 4-inch aluminum midrange plus a dedicated 6.5-inch aluminum woofer. Watch for: Erin measured very low 83dB/2.83V/1m sensitivity; his 110W Parasound was insufficient for the high-level test and the more powerful HINT 6 was needed.
On the Klipsch RP-600M II side: Redesigned waveguide extends flush to the baffle edge, reducing diffraction compared to the original RP-600M. The tradeoff: 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.
Buy the ELAC Uni-Fi Reference UBR62 if sound quality matters more than the price. Buy the Klipsch RP-600M II if the price matters more than sound quality.

ELAC Uni-Fi Reference UBR62: $1,199/pair Amazon
Pros: True three-way stand-mount using a 1-inch tweeter concentrically mounted in a 4-inch aluminum midrange plus a dedicated 6.5-inch aluminum woofer. Erin found the directivity and overall tonality well controlled, with dual front slot vents minimizing placement sensitivity and cabinet bracing suppressing obvious coloration. The mostly 5-ohm-or-higher load is manageable for a genuinely 4-ohm-capable amplifier, and the coherent concentric upper range supports stable imaging across seats.
Cons: Erin measured very low 83dB/2.83V/1m sensitivity; his 110W Parasound was insufficient for the high-level test and the more powerful HINT 6 was needed. Impedance reaches 4 ohms near 50Hz (Erin), while woofer excursion and bass output were less capable than expected for the cabinet size. A broad 500-700Hz rise and associated lower/female-vocal coloration were audible, and the slightly subdued listening-window treble is necessary to avoid an overly bright in-room balance rather than evidence of ruler-flat axial tuning.

Klipsch RP-600M II: $489.99 Amazon
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.
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.
