Short answer: the ELAC Debut 3.0 DF63. It ranks #35 of 68 floorstanding speakers by sound quality at $649; the Klipsch RP-8000F II ranks #52 and costs $1800, 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-8000F II offers: Highest sensitivity of the RP II floorstander line (~92dB measured) and the best dynamics/compression behavior of the three under load - the cleanest at high output. Dual 8-inch woofers and the highest power handling in the line. Watch for: Mid-bass sounds lean despite the dual 8-inch woofers, and bass extension disappointed for its size - expected to reach 50Hz, didn’t get there in-room. Has its own edgy upper-mid bump (2-6kHz) that’s harder to EQ out than the other two models’ issues, since it stems from the vertical horn/woofer offset rather than simple tonal balance. The most placement-critical of the three, with the narrowest horizontal (~40-50 degrees) and vertical (+5/-10 degrees) dispersion.
Buy the ELAC Debut 3.0 DF63. It ranks higher for sound quality than the Klipsch RP-8000F 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-8000F II. It ranks near the bottom of the 68 floorstanding speakers, so look higher up the list instead.
