Short answer: the AsciLab F6Bs. It ranks #20 of 222 bookshelf speakers by sound quality (rated 4.5/5); the ELAC Debut 2.0 B6.2 ranks #149 (rated 3.5/5).
The ELAC Debut 2.0 B6.2 is the deeper-bass pick. Large bookshelf speakers that play very loud with low distortion and decent bass, a solid budget choice. Its bass reaches about 64Hz before falling 3dB, against 82Hz for the AsciLab F6Bs. 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 AsciLab F6Bs is the better-sounding option. A slim, sealed bookshelf speaker that mounts flat on a wall bracket, with accurate sound and wide, even dispersion for a great price. The tradeoff: AsciLab’s own site shows the F6Bs sold out, though it remains in stock through resellers like Audiophonics and Tested Audio.
Buy the AsciLab F6Bs. It is rated higher for sound quality than the ELAC Debut 2.0 B6.2.
