Short answer: the ELAC Debut 3.0 DB63, if you are buying new. The DIYSG HTM-12 v2 ranks higher than it (#14 vs #50 of 203 bookshelf speakers, 4.5/5 vs 4.2/5) but is discontinued, so only consider it used; the ELAC Debut 3.0 DB63 is still sold new at $499.
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 DIYSG HTM-12 v2 is the deeper-bass pick. Purpose-built high-output cinema kit pairing a 12-inch woofer with a compression driver in a large SEOS waveguide. Its bass reaches about 67Hz before falling 3dB, against 76Hz for the ELAC Debut 3.0 DB63. The catch: Erin measured F3 at approximately 67Hz, the normal efficiency/bass-extension tradeoff of a high-sensitivity 12-inch design, so a subwoofer is mandatory.
Buy the ELAC Debut 3.0 DB63 if you want one new; the DIYSG HTM-12 v2 is discontinued, so only look for it used.

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 HTM-12 v2: $920 per pair per kit Discontinued DIY Sound Group eBay
Older model: the DIYSG HTM-12 v1 (ranked lower, rated 3.8/5).
Pros: Purpose-built high-output cinema kit pairing a 12-inch woofer with a compression driver in a large SEOS waveguide. Erin measured 91dB/2.83V/1m sensitivity, extraordinarily low distortion (still below 1% to about 60Hz at 102dB) and only about 0.5dB tweeter compression at the same level. Horizontal directivity is consistent and crossover integration is unusually good, so response corrections remain EQ-friendly. The benign impedance curve can be driven by many capable AVRs. Measured bass extension of 67Hz (-3dB), with a measured sensitivity of 91dB.
Cons: Erin measured F3 at approximately 67Hz, the normal efficiency/bass-extension tradeoff of a high-sensitivity 12-inch design, so a subwoofer is mandatory. A few narrow resonances appear in the response, impedance and decay plots; Erin suggested crossover/component investigation could improve them. Vertical radiation narrows around the crossover, the unfinished kit requires cabinet assembly and finishing, and its broad baffle is visually and physically substantial. Discontinued.
