Short answer: the ELAC Debut 3.0 DB63 for better sound quality, the Dayton Audio B652-AIR for the lower price. The ELAC Debut 3.0 DB63 ranks #41 of 131 bookshelf speakers at $499. The Dayton Audio B652-AIR ranks #130 at $77.99, $421.01 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 Dayton Audio B652-AIR offers: AMT (Air Motion Transformer) tweeter offers a novel driver technology at a very low price point, and the full-range woofer keeps the crossover simple. Watch for: Amir says this speaker “does everything wrong that you want to avoid in modern speaker design” - the woofer runs full-bandwidth without a proper crossover filter, causing a 340Hz suckout from woofer/tweeter cancellation and multiple additional peaks and dips. The AMT tweeter lacks adequate damping (only a capacitor and resistor), and the thin cabinet resonates audibly. Listening tests revealed “piercing and distorted highs” and “distorted lisping” on female vocals. Amir specifically criticized other reviewers for calling these speakers “clear and clean” with “five star performance,” calling such assessments “embarrassing,” and recommended the Pioneer SP-BS22-LR instead.
Buy the ELAC Debut 3.0 DB63 if sound quality matters more than the price. Buy the Dayton Audio B652-AIR if the price matters more than sound quality.
If sound quality matters at all to you, skip the Dayton Audio B652-AIR. It ranks near the bottom of the 131 bookshelf speakers, so look higher up the list instead.
