Short answer: the ELAC Debut 3.0 DF63, if you are buying new. The JBL 4367 ranks higher than it (#16 vs #73 of 188 floorstanding speakers, 4.6/5 vs 4.2/5) but is discontinued, so only consider it used; the ELAC Debut 3.0 DF63 is still sold new at $1,298. The JBL 4367’s replacement, the JBL 4369, is rated 4.7/5.
The ELAC Debut 3.0 DF63 is the more accurate choice. 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. Its measured preference score, a predictor of how neutral it sounds, is 5.83 against 5.07 for the JBL 4367. The catch: A genuine measured resonance around 200-300Hz (visible in frequency response, impedance, and group delay) causes an audible “droning” coloration on female vocals.
The JBL 4367 is the better-sounding, deeper-bass option. Three-way design pairing a 15” front-ported woofer with a compression driver on a controlled-dispersion horn/waveguide, crossed over at 700Hz. Its bass reaches about 43Hz before falling 3dB, against 71Hz for the ELAC Debut 3.0 DF63. Watch for: At roughly $16500/pair, this is a major investment: the reviewer recommends buying from a dealer with a liberal return policy.
Buy the ELAC Debut 3.0 DF63 new; the JBL 4367 is no longer sold new, so it only makes sense as a used find.

ELAC Debut 3.0 DF63: $1,298 per pair Amazon eBay
Same family: the ELAC Debut 3.0 DB53 (smaller bookshelf, estimated 3.9/5), the ELAC Debut 3.0 DB63 (larger bookshelf, rated 4.2/5), the ELAC Debut 3.0 DF53 (smaller floorstanding, ranked lower, estimated 4.2/5), the ELAC Debut 3.0 DC53 (smaller center, estimated 3.4/5) and the ELAC Debut 3.0 DC63 (larger center, estimated 3.5/5).
Pros: 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 Reserve R500 (too much high-frequency narrowing, less neutral) and considered ahead of the Polk Audio Reserve R700 as well. Measured bass extension of 71Hz (-3dB), with a measured sensitivity of 86.6dB.
Cons: 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.

JBL 4367: $16,500 per pair Discontinued eBay
Newer model: the JBL 4369, ranked higher, estimated 4.7/5.
Same family: the JBL 4309 (smallest bookshelf, rated 3.3/5), the JBL 4312G (bookshelf, estimated 3.9/5), the JBL 4349 (largest bookshelf, rated 3.6/5) and the JBL 4369 (larger floorstanding, ranked higher, estimated 4.7/5).
Pros: Three-way design pairing a 15” front-ported woofer with a compression driver on a controlled-dispersion horn/waveguide, crossed over at 700Hz. On-axis frequency response is nearly dead flat, holding within about ±1.5dB, with the listening window tracking it closely except right at the crossover. Distortion stays below 1% THD across the entire audible band at both 86dB and 96dB. Compression/dynamic-range linearity is exceptional: within about a quarter of a dB from 76dB to 102dB, among the best the reviewer has measured. High sensitivity (about 92.6dB average) eases the amplifier match despite the speaker’s size. Minimal rear radiation thanks to the 15” woofer’s directivity and front-firing ports: rear energy runs about 20dB down from the primary wavefront, giving it a near-cardioid radiation pattern. Well-controlled horn directivity keeps the soundstage from noticeably shifting in width across the 700Hz crossover region. A natural high-frequency rolloff above about 7-8kHz gives it an easy, non-fatiguing character for extended listening sessions. Measured bass extension of 43Hz (-3dB), with a measured sensitivity of 92.5dB.
Cons: At roughly $16500/pair, this is a major investment: the reviewer recommends buying from a dealer with a liberal return policy. Vertical response shows dips beyond about ±10-20°, with a larger null further out: an inherent trade-off of mating a 15” woofer to a horn compression driver at a 700Hz crossover, since crossing lower would hurt power handling and dynamic range. Horizontal directivity isn’t perfectly consistent with frequency: narrow (about ±20°) through 200-800Hz, briefly widening to near ±50° above the crossover, then narrowing again at high frequency. An unusual, non-constant pattern. The high-frequency rolloff that gives it an easy-listening character also reduces the sense of air and space in the soundstage when listening from off-center seats. Massive and heavy (about 120 lbs, roughly 36-37” tall): needs to be raised on a stand to bring the horn to ear level, and isn’t something one person easily moves alone. Only modest EQ adjustment is available on the speaker itself (about ±1-2dB bass/treble trim). Discontinued.
