Short answer: the Polk Signature Elite ES20. It ranks #119 of 222 bookshelf speakers by sound quality, rated 3.7/5, at $398.98. The ELAC Debut 2.0 B6.2 ranks #149, rated 3.5/5, at $329, $69.98 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the ELAC Debut 2.0 B6.2: 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 Polk Signature Elite ES20 is the deeper-bass choice. Large, efficient bookshelf speakers with unusually deep bass for the price and wide horizontal coverage. Its bass reaches about 55.7Hz before falling 3dB, against 64Hz for the ELAC Debut 2.0 B6.2. The tradeoff: Predicted in-room smoothness of 0.238 and directivity-index consistency of 3.81 are average rather than class-leading.
Buy the Polk Signature Elite ES20. It is rated higher for sound quality, and saving $69.98 with the ELAC Debut 2.0 B6.2 does not make up for the sound-quality gap.
