Short answer: the ELAC Debut 2.0 B6.2. It ranks #149 of 222 bookshelf speakers by sound quality, rated 3.5/5, at $329; the ATC SCM19 ranks #209, rated 2.4/5, and costs $3,750, so there is little reason to consider the other one.
The ELAC Debut 2.0 B6.2 is the better-sounding option. Large bookshelf speakers that play very loud with low distortion and decent bass, a solid budget choice. The catch: A good size resonant peak around 700Hz stands out from an otherwise smooth response and lingers in cumulative spectral decay (waterfall) measurements: in one reviewer’s sighted A/B test, reducing it by about 5dB via EQ made a noticeable but not dramatic difference.
The case for the ATC SCM19: A heavy, sealed pro style ATC bookshelf speaker with a very dense cabinet and low distortion at high volume. Watch for: Some stored energy resonance around 500-700Hz, 4dB bump around 700Hz.
Buy the ELAC Debut 2.0 B6.2. It is rated higher for sound quality than the ATC SCM19 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
