Short answer: the ELAC Debut 3.0 DB63. It ranks #50 of 203 bookshelf speakers by sound quality (rated 4.2/5) at $499 and is still sold new; the JBL 4319 ranks #195 (rated 2.3/5) and is discontinued, so it is only an option used.
The ELAC Debut 3.0 DB63 is the better-sounding choice. 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. The catch: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow.
The JBL 4319 is the deeper-bass option. High sensitivity around 90dB and controlled bass distortion mean the large 12” woofer plays loud with copious bass and modest amplifier power needs. Its bass reaches about 58.6Hz before falling 3dB, against 76Hz for the ELAC Debut 3.0 DB63. The catch: CEA2034 spinorama shows a pronounced 800Hz dip and a comb-filtering pattern in the woofer response consistent with a delayed reflected source, plus poor and uneven vertical directivity.

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 4319: $4,000 per pair Discontinued eBay
Pros: High sensitivity around 90dB and controlled bass distortion mean the large 12” woofer plays loud with copious bass and modest amplifier power needs. Impedance dips are well controlled, so it isn’t a hard speaker to drive despite its size. User-adjustable midrange and treble level controls are built into the back panel. Measured bass extension of 58.6Hz (-3dB), with a measured sensitivity of 89.5dB.
Cons: CEA2034 spinorama shows a pronounced 800Hz dip and a comb-filtering pattern in the woofer response consistent with a delayed reflected source, plus poor and uneven vertical directivity. The reviewer described the sound as “boxy and closed in with some brightness” and could not recommend it “unless you like looking at it more than listening to it.” At 23.5” tall, it’s closer to a small tower than a typical bookshelf speaker. Discontinued.
