Short answer: the Revel M126Be, if you are buying new. The Revel M106 ranks higher than the ELAC Debut 3.0 DB63 (#9 vs #50 of 203 bookshelf speakers) but is discontinued; its replacement, the Revel M126Be, is rated 4.3/5 at $4,400 and is still sold new.
The case for the ELAC Debut 3.0 DB63: 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 Revel M106 is the better-sounding, deeper-bass pick. CEA2034 spinorama shows a fairly even on-axis response with no obvious resonances, and a listening window that sits comfortably above the on-axis curve. Its bass reaches about 60Hz before falling 3dB, against 76Hz for the ELAC Debut 3.0 DB63. Watch for: Some directivity error and response variation shows up in the crossover region.
Buy the Revel M126Be, the replacement for the discontinued Revel M106; it is rated higher for sound quality than the ELAC Debut 3.0 DB63.

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.

Revel M106 Discontinued eBay
Newer model: the Revel M126Be, ranked lower, rated 4.3/5.
Same family: the Revel M105 (smaller bookshelf, rated 4.2/5), the Revel F206 (smaller floorstanding, rated 4.5/5), the Revel F208 (larger floorstanding, rated 4.5/5), the Revel Performa3 C205 (smaller center, rated 4.1/5) and the Revel Performa3 C208 (larger center, rated 4/5).
Pros: CEA2034 spinorama shows a fairly even on-axis response with no obvious resonances, and a listening window that sits comfortably above the on-axis curve. Predicted in-room response is called “near ideal” by the reviewer, with a smooth downward slope from bass to treble. Distortion at 96dB SPL/1m stays well controlled through the midrange and treble. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 86dB.
Cons: Some directivity error and response variation shows up in the crossover region. Horizontal beamwidth of about ±50 degrees is on the narrower side. Vertical directivity requires staying within about ±20 degrees of the reference axis for accurate tonal balance. Minimum impedance dips to 4.6 ohms with several peaks, a moderately demanding load for a compact bookshelf speaker. Discontinued.
