Short answer: the ELAC Debut 3.0 DB63. It ranks #50 of 203 bookshelf speakers by sound quality, rated 4.2/5, at $499; the DIYSG HT-10 ranks #154, rated 3.3/5, at $496. The price gap is small enough that the sound-quality ranking should decide it.
The ELAC Debut 3.0 DB63 is the better-sounding choice. 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 case for the DIYSG HT-10: A distinct kit design from DIYSG HTM-12 v2, a 10” ported LCR/surround box built around a Celestion woofer and compression tweeter. The tradeoff: On-axis deviation of 0.537dB is rough, with a pronounced -0.43dB per octave downward tilt giving it a notably dark tonal character, a somewhat resonant bass-alignment Q of 1.76, and the Harman in-room bass extension estimate is a modest 56Hz for a 10” woofer.
Buy the ELAC Debut 3.0 DB63. It is rated higher for sound quality, and saving $3 with the DIYSG HT-10 does not make up for the sound-quality gap.

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.

DIYSG HT-10: $496 per pair DIY Sound Group eBay
Same family: the DIYSG HT-8 (smaller bookshelf, ranked lower, rated 2.9/5) and the DIYSG HT-12 (larger bookshelf, ranked higher, rated 3.5/5).
Pros: A distinct kit design from DIYSG HTM-12 v2, a 10” ported LCR/surround box built around a Celestion woofer and compression tweeter. Sound-power smoothness of 0.197 is solid for a budget DIY kit. Measured bass extension of 73.4Hz (-3dB), with a measured sensitivity of 91.3dB.
Cons: On-axis deviation of 0.537dB is rough, with a pronounced -0.43dB per octave downward tilt giving it a notably dark tonal character, a somewhat resonant bass-alignment Q of 1.76, and the Harman in-room bass extension estimate is a modest 56Hz for a 10” woofer. It ships as a flat-pack cabinet kit requiring assembly, sold in a minimum order of two units.
