Short answer: the ELAC Debut 3.0 DB63. It ranks #50 of 203 bookshelf speakers by sound quality, rated 4.2/5, at $499; the JBL 4349 ranks #128, rated 3.6/5, and costs $7,500, so there is little reason to consider the other one.
The ELAC Debut 3.0 DB63 is the better-sounding pick. 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer, in a robustly built cabinet for the price. Watch for: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow.
The JBL 4349 is the deeper-bass pick. A high-output studio-monitor design with a large 12-inch woofer, compression driver and front-panel high-frequency controls. Its bass reaches about 51.3Hz before falling 3dB, against 76Hz for the ELAC Debut 3.0 DB63. Watch for: Large, heavy and costly, with response/directivity imperfections that keep measured preference below less expensive neutral monitors.
Buy the ELAC Debut 3.0 DB63. It is rated higher for sound quality than the JBL 4349 and costs less, which makes it the one to get unless you need something the other one does better.

ELAC Debut 3.0 DB63: $499.00 per pair Amazon Crutchfield eBay
Older model: the ELAC Debut 2.0 B6.2 (ranked lower, rated 3.5/5).
Same family: the ELAC Debut 3.0 DB53 (smaller bookshelf, estimated 3.9/5), the ELAC Debut 3.0 DF53 (smaller floorstanding, estimated 4.2/5), the ELAC Debut 3.0 DF63 (larger floorstanding, rated 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: 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer, in a robustly built cabinet for the price. Shallow bass rolloff (F3 76Hz, F10 40Hz) allows placement close to a wall without excessive boominess, useful for smaller living rooms. Solid measured performance for the price: on-axis linearity within about 2.5dB, impedance dipping only to about 4.4 ohms (easily AVR-driven), and roughly 20-26dB of usable dynamic range. A clear improvement over its sibling ELAC DB62, which has a sibilance issue tied to the crossover that can’t be fixed with EQ. Wide horizontal radiation of about ±60°, giving a spacious soundstage. Distortion looks good at a moderate 86dB and still reasonable at 96dB. Takes well to EQ correction: the reviewer provides a specific filter set (a low-shelf boost at 650Hz plus peaking cuts/boosts at 550Hz, 660Hz, and 3kHz) that meaningfully smooths out its known deviations. Measured bass extension of 76Hz (-3dB), with a measured sensitivity of 86.2dB.
Cons: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow. A high-Q resonance around 650-750Hz shows up clearly in measurements, though the reviewer couldn’t reliably hear it in his own A/B testing. A dip around 2-3kHz (roughly 1-2dB) slightly reduces speech intelligibility and attack in the upper midrange. Directivity droops above about 2kHz as the midwoofer narrows toward its beaming frequency while the tweeter’s pattern behaves differently: an inherent trade-off of physically separated drivers that can’t be fully corrected without introducing other issues. Multitone distortion crosses the reviewer’s 3% threshold in the 200Hz-1kHz range, and adding a subwoofer at an 80Hz crossover only modestly reduces it. Toeing the speaker away from the listener loses noticeable top-end air and cymbal energy, giving a softer upper register. Practical loudness ceiling is around 90dB at typical listening distance before midrange distortion and bass attack begin to degrade. Still needs a subwoofer for extension below about 40Hz.

JBL 4349: $7,500 per pair eBay
Same family: the JBL 4309 (smaller bookshelf, ranked lower, rated 3.3/5), the JBL 4312G (smaller bookshelf, ranked higher, estimated 3.9/5), the JBL 4367 (smaller floorstanding, rated 4.6/5) and the JBL 4369 (larger floorstanding, estimated 4.7/5).
Pros: A high-output studio-monitor design with a large 12-inch woofer, compression driver and front-panel high-frequency controls. Its local Spinorama scores are 4.32 raw and 6.05 with a subwoofer, with strong 36Hz measured extension. Measured bass extension of 51.3Hz (-3dB).
Cons: Large, heavy and costly, with response/directivity imperfections that keep measured preference below less expensive neutral monitors. Four-ohm impedance and high output capability call for substantial amplification.
