Short answer: the ELAC Debut 3.0 DF63. It ranks #35 of 71 floorstanding speakers by sound quality at $649; the Klipsch RP-6000F II ranks #54 and costs $1500, so there is not much of a tradeoff to weigh.
What the ELAC Debut 3.0 DF63 offers: Three-driver floorstanding layout: two 6” dedicated midbase drivers plus a separate 6” mid-range driver (confirmed by measuring different driver impedance/inductance) and a 1” dome tweeter, each woofer given its own stuffed chamber inside the cabinet. The dedicated midrange driver keeps distortion low even at higher output, avoiding the intermodulation grain typical of two-way bookshelf designs. The waveguide keeps high-frequency directivity well controlled, and overall horizontal directivity is good up to about 2kHz. Harmonic distortion looks good at both 86dB and 96dB, and multitone distortion stays below the reviewer’s 3% threshold. A shallow bass rolloff (F3 71Hz, F10 29Hz) lets it extend fairly low without a hard cutoff. Preferred by the reviewer over the similarly-priced Polk R500 (too much high-frequency narrowing, less neutral) and considered ahead of the Polk R700 as well. Watch for: A genuine measured resonance around 200-300Hz (visible in frequency response, impedance, and group delay) causes an audible “droning” coloration on female vocals. A mild peak around 10kHz makes shakers and similar high-frequency percussion jump too far forward in the mix; needed about 2dB of EQ to tame in testing. A dip in the 1-3kHz range gives the speaker a warm, slightly veiled character - the reviewer suspects the tweeter crossover point (around 2-3kHz) is set a bit high and could be lowered to fill this in. Directivity shows a noticeable handoff mismatch around 2.5kHz where the midrange driver hands off to the tweeter, though it’s minor at the -6dB point. Vertical directivity is narrower than horizontal, so listeners need to stay close to the tweeter axis. Low EPDR (about 1.5 ohms minimum) means a Class AB amplifier should be well-ventilated. Best positioned pointed directly at the listener and closer to the front wall - toeing it out into the room causes too much high-frequency rolloff.
What the Klipsch RP-6000F II offers: Highest power handling and clean, well-behaved compression at typical volumes. Precise imaging from the controlled horn directivity. Watch for: Worse baffle-step coloration than the smaller RP-5000F II (3-4dB swing vs 2dB), plus a sibilance issue the 5000F doesn’t have - a real regression in tonal balance despite the higher price. Bass extension is mixed - less deep at -3dB (67Hz) than the 5000F - and needs a subwoofer regardless. Narrow horizontal dispersion (~50-60 degrees).
Buy the ELAC Debut 3.0 DF63. It ranks higher for sound quality than the Klipsch RP-6000F II and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Klipsch RP-6000F II. It ranks near the bottom of the 71 floorstanding speakers, so look higher up the list instead.
