Short answer: the Revel F328Be for better sound quality, the ELAC Debut 3.0 DF63 for the lower price. The Revel F328Be ranks #8 of 71 floorstanding speakers at $13600. The ELAC Debut 3.0 DF63 ranks #35 at $649, $12951 cheaper.
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 Revel F328Be offers: CEA2034 spinorama shows a quite flat on-axis response with superb directivity and efficiency above 90dB. Predicted in-room response is extremely accurate, with a smooth ~5dB downward slope from bass to treble that suits typical rooms without correction. Early reflections sum very nicely with the direct sound. Horizontal beamwidth of about ±70 degrees is wide and quite smooth. At 96dB SPL/1m distortion stays easily below the reviewer’s audibility threshold across nearly the whole range. Watch for: Vertical directivity is asymmetric - the reviewer recommends staying between -20 and +40 degrees relative to the tweeter axis, reflecting the driver layout of this three-way tower. Impedance dips to a minimum of 3 ohms with an additional resonance-driven phase swing, calling for an amplifier comfortable with a demanding load. Very expensive and very heavy (51 kg each).
