Short answer: the Ascend Acoustics HTM-200SE2. It ranks #7 of 178 bookshelf speakers by sound quality, rated 4.3/5, at $368. The ELAC Debut 2.0 B5.2 ranks #91, rated 3.2/5, at $269, $99 cheaper, which does not close the gap in sound quality.
The Ascend Acoustics HTM-200SE2 is the better-sounding pick. High-quality manufacturer NFS data shows 0.385dB on-axis average absolute deviation, 0.428 listening-window smoothness, and unusually even 80-degree dispersion in both planes. Watch for: Limited bass is the main tradeoff, measuring 87.9Hz at -3dB, 71.8Hz at -6dB, and 51.3Hz at -12dB; its preference score falls to 4.98 without a subwoofer.
The ELAC Debut 2.0 B5.2 is the deeper-bass choice. Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Its bass reaches about 60Hz before falling 3dB, against 87.9Hz for the Ascend Acoustics HTM-200SE2. The tradeoff: Erin measured a broad +3dB step beginning around 1.5kHz; the resulting elevated upper range sounds tonally uneven even though it is not a narrow, sharp resonance.
Buy the Ascend Acoustics HTM-200SE2. It is rated higher for sound quality, and the $99 saving on the ELAC Debut 2.0 B5.2 is not enough to make up the difference.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
