Short answer: the ELAC Debut 3.0 DB63, if you are buying new. The Selah Audio Integrity ranks higher than it (#42 vs #50 of 203 bookshelf speakers, 4.3/5 vs 4.2/5) but is discontinued, so only consider it used; the ELAC Debut 3.0 DB63 is still sold new at $499.
What the ELAC Debut 3.0 DB63 does well: 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 tradeoff: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow.
The Selah Audio Integrity is the deeper-bass choice. CEA2034 spinorama shows a very good overall on-axis response with wide, even beamwidth and directivity through the midrange from its 3-way design. Its bass reaches about 43.9Hz before falling 3dB, against 76Hz for the ELAC Debut 3.0 DB63. The catch: A dip/perturbation around 1.7kHz shows up in both on- and off-axis measurements, correlating with a matching midrange distortion peak at the same frequency.
Buy the ELAC Debut 3.0 DB63 if you want one new; the Selah Audio Integrity is discontinued, so only look for it used.

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.

Selah Audio Integrity: $750 per pair Discontinued eBay
Pros: CEA2034 spinorama shows a very good overall on-axis response with wide, even beamwidth and directivity through the midrange from its 3-way design. Nominal impedance sits around 5.5 ohms, an easier load than many small speakers. A tribute design to DIY speaker builder Jeff Bagby, priced at $750 per pair as a kit. Measured bass extension of 43.9Hz (-3dB), with a measured sensitivity of 80.5dB.
Cons: A dip/perturbation around 1.7kHz shows up in both on- and off-axis measurements, correlating with a matching midrange distortion peak at the same frequency. Very inefficient, requiring more amplifier power for the same volume. Susceptible to subsonic content, which can cause massive distortion without a high-pass filter. Requires building the cabinets and installing the drivers yourself. Discontinued.
