Short answer: the ELAC Debut 3.0 DB63 ranks #41 of 131 bookshelf speakers by sound quality at $499; the StarkSound Beta 5 ranks #46 at $499. Close enough in price that the sound-quality gap is the deciding factor.
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 StarkSound Beta 5 offers: Impressive bass extension for the price - F3 at 52Hz, F10 at 37Hz, reaching down to 40-50Hz in-room with solid kick-drum impact. Good harmonic distortion control at both moderate and loud listening levels. Solid build with a thick polycarbonate baffle meant to reduce cabinet resonance. Watch for: Sensitivity undershoots its own spec - rated 86dB, measured closer to 83dB. A resonance artifact shows up independently in the on-axis response, burst decay, and impedance measurements, hurting directivity. Multitone distortion spikes to about 10% in the 800Hz-1kHz range, tied to woofer excursion - a subwoofer crossover helps. Needs to sit close to the wall (about 10 inches) or be EQ’d if placed further out, since the midrange sounds thin and the treble boosted otherwise.
Buy the ELAC Debut 3.0 DB63. It ranks higher for sound quality than the StarkSound Beta 5 at the same price, so there is no real case for the other one.
