Short answer: the Selah Audio Integrity for better sound quality, the ELAC Debut 3.0 DB63 for the lower price. The Selah Audio Integrity ranks #37 of 131 bookshelf speakers at $750. The ELAC Debut 3.0 DB63 ranks #41 at $499, $251 cheaper.
What the ELAC Debut 3.0 DB63 offers: 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. Watch for: 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.
What the Selah Audio Integrity offers: 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. Watch for: 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.
