Short answer: the ELAC Debut 3.0 DB63. It ranks #50 of 203 bookshelf speakers by sound quality (rated 4.2/5) at $499 and is still sold new; the Dayton Audio MK602X ranks #192 (rated 2.4/5) and is discontinued, so it is only an option used.
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 catch: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow.
What the Dayton Audio MK602X does well: Inexpensive, compact two-way with a 6.5-inch glass-fiber woofer and 1-inch silk dome. The tradeoff: The top end sits roughly 5dB above the midband, producing brightness that can masquerade as detail.

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.

Dayton Audio MK602X: $149 per pair Discontinued eBay
Same family: the Dayton Audio MK402 (smaller bookshelf, estimated 3.2/5), the Dayton Audio MK402X (smaller bookshelf, rated 3.4/5) and the Dayton Audio MK442 (center, estimated 2.9/5).
Pros: Inexpensive, compact two-way with a 6.5-inch glass-fiber woofer and 1-inch silk dome. Erin measured respectable small-box extension (72Hz F3 and 43Hz F10) and roughly 85dB sensitivity. The cabinet and removable grille are tidy for the price, and the response can be made less bright with broad treble EQ when listening close to the reference axis. Measured bass extension of 72Hz (-3dB), with a measured sensitivity of 85dB.
Cons: The top end sits roughly 5dB above the midband, producing brightness that can masquerade as detail. More seriously, the low-order woofer filter creates a 4-5dB directivity discontinuity around 2kHz; because the reflected sound differs from the direct sound, equalization cannot fully fix it. Erin also found multiple resonances around 900Hz and rising distortion/compression from the woofer at higher levels. Its 4-ohm nominal load and modest 85dB measured sensitivity demand more amplifier current than the price suggests, while the 72Hz F3 makes a subwoofer advisable despite the relatively low F10. Discontinued.
