Short answer: the ELAC Debut 2.0 B5.2. It ranks #86 of 168 bookshelf speakers by sound quality, rated 3.2/5, at $269. The Polk Signature Elite ES10 ranks #99, rated 3.1/5, at $199, $70 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the ELAC Debut 2.0 B5.2: Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. 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.
Why pick the Polk Signature Elite ES10: Ultra-compact passive satellite/bookshelf speaker designed for tight spaces or surround-channel deployment. The catch: Rating estimated based on measured Signature Elite siblings.
Buy the ELAC Debut 2.0 B5.2. It is rated higher for sound quality, and saving $70 with the Polk Signature Elite ES10 does not make up for the sound-quality gap.
Worth knowing: the Polk Signature Elite ES10 has not been measured yet. Its rating is estimated from related models, with a likely range of 2.9 to 3.3, so treat this verdict as provisional.

The Two Speakers In Full
ELAC Debut 2.0 B5.2: $269.00 per pair Amazon eBay
Newer model: the ELAC Debut 3.0 DB53, ranked higher, estimated 3.9/5, released Mar 2025. See every ELAC Debut generation.
Same family: the ELAC Debut 2.0 B6.2 (larger bookshelf, rated 3.5/5).
Pros: Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Erin demonstrated that a single high-shelf filter centered near 1.6kHz, about -2dB with Q near 2, substantially improves linearity. Moderate roughly +/-50-60 degree horizontal coverage balances room interaction and image focus. The front port makes close-to-wall placement practical. Erin measured F3 near 60Hz and F10 near 40Hz, useful extension for a compact 5.25-inch two-way. Harmonic distortion is mostly below 1% at 86dB/1m, and low-frequency distortion is better than its size might suggest. Compact cabinet and inexpensive pair pricing make it a workable EQ-assisted desktop or small-room system. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 83dB.
Cons: 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. Native response spans roughly -2.6 to +4dB around the mean, so this is not a neutral speaker without correction. Sensitivity is only about 83dB after correcting the shelf, demanding materially more amplifier voltage than ELAC’s 86dB specification implies. Vertical response changes substantially outside roughly +/-10 degrees of tweeter height. Dynamic compression is the larger limitation: at the highest sweep level it loses roughly 1-1.5dB through the midrange, and even the 86dB trace shows unusual nonlinearity that may involve crossover heating. At about 96dB, multitone distortion rises audibly around 600Hz; an 80-120Hz subwoofer crossover helps but does not turn it into a high-output design. Erin recommends the larger ELAC Debut 2.0 B6.2 instead when EQ is unavailable.

Polk Signature Elite ES10: $199.00 per pair Passive Estimated Amazon eBay
Same family: the Polk Signature Elite ES15 (larger bookshelf, ranked higher, rated 3.5/5), the Polk Signature Elite ES20 (larger bookshelf, rated 3.7/5), the Polk Signature Elite ES50 (smallest floorstanding, estimated 3.8/5), the Polk Signature Elite ES55 (floorstanding, estimated 4/5), the Polk Signature Elite ES60 (largest floorstanding, rated 3.4/5), the Polk Audio Signature Elite ES30 (smaller center, estimated 3.5/5), the Polk Audio Signature Elite ES35 (larger center, estimated 3.4/5), the Polk Audio Signature Elite ES8 Subwoofer (smallest subwoofer, estimated 3.2/5), the Polk Audio Signature Elite ES10 Subwoofer (subwoofer, estimated 3.7/5) and the Polk Audio Signature Elite ES12 Subwoofer (largest subwoofer, estimated 3.8/5). See every Polk Signature generation.
Pros: Ultra-compact passive satellite/bookshelf speaker designed for tight spaces or surround-channel deployment. Features the same 1-inch Terylene dome tweeter found across the Signature Elite series for extended high-frequency response up to 40kHz, alongside a 4-inch mica-reinforced woofer and rear Power Port. Clean off-axis directivity and smooth treble matching the measured Polk Signature Elite ES15 and Polk Signature Elite ES20 siblings, with integrated keyhole slots for flexible wall mounting.
Cons: Rating estimated based on measured Signature Elite siblings. Compact 4-inch enclosure limits bass extension below 75Hz, requiring high-pass crossover integration with an active subwoofer for balanced full-range listening.
