Short answer: the ELAC Debut 2.0 B6.2, because its flaws are narrower than the Polk Monitor XT20’s. The XT20 is a two-way with a 1-inch tweeter and 6.5-inch woofer whose notably bright treble sits roughly 1-5dB above the midrange, a character shared across the whole Polk XT line. The B6.2 is reasonably flat on-axis with even horizontal directivity, though a good size resonant peak around 700Hz and a directivity error around 3.3kHz remain.
What the ELAC Debut 2.0 B6.2 gets right: Reasonably flat on-axis and listening-window response with reasonably even horizontal directivity. The catch: A good size resonant peak around 700Hz, directivity error around 3.3kHz.
On the Polk Monitor XT20 side: Two-way bookshelf design with a 1” tweeter and 6.5” woofer. Set against that: Notably bright treble, elevated roughly 1-5dB above the midrange depending on frequency - a characteristic shared across the whole Polk XT.
Buy the ELAC Debut 2.0 B6.2. It is rated higher for sound quality, and saving $50 with the Polk Monitor XT20 does not make up for the sound-quality gap.

Pros: Reasonably flat on-axis and listening-window response with reasonably even horizontal directivity, holding about ±60° up to roughly 8kHz for consistent stereo width whether aimed directly at the listener or toed out. Its larger-than-typical woofer lets it play very loud with minimal distortion, staying under about 1% THD down to 50Hz at 86dB, and minimum impedance stays a comfortable 5-6 ohms. In-room bass extension reaches about 50Hz without much trouble, enough for a solid kick-drum sound. Takes equalization very well - correcting the on-axis response doesn’t cost sensitivity through the midrange, and the underlying directivity behavior (diffraction, vertical mismatch) is mild enough that EQ alone gets most of the way to a well-balanced sound. Vertical tolerance is asymmetric and fairly forgiving: about 10° above the tweeter axis and 20° below it before tonal balance meaningfully shifts. One reviewer called it “a good speaker” with “a good price” rather than just good-for-the-price, and found it fairly neutral overall in-room. Measured bass extension of 64Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: 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. Directivity error shows up around 3.3kHz, and the upper-midrange around 4-6kHz stood out as edgy and sharp, almost sibilant at times, in casual listening - the predicted in-room response shows a lack of energy between 1-2kHz and a bit too much above that, which one reviewer thought would sound bright. Distortion at 96dB SPL/1m shows two harmonic peaks the reviewer says “should not be there,” one from woofer breakup around 400Hz and another around 7-8kHz from the tweeter, and multitone distortion approaches 10% in the 500-800Hz range at that output level. Real compression shows up even at moderate volume and worsens at 96dB and above, with the woofer clearly giving up around 60-70Hz - a subwoofer is recommended for anyone wanting to listen loud, since running it full-range at high output costs real dynamic range in the midbass and bass. Don’t place it close to a wall - boundary reinforcement adds a midbass bump that undoes the otherwise smooth, linear response. Getting the best out of it takes EQ (taming the 700Hz peak, filling in the 1-2kHz dip, and trimming the highs).

Polk Monitor XT20: $279.00 per pair Amazon Crutchfield eBay
Pros: Two-way bookshelf design with a 1” tweeter and 6.5” woofer, part of Polk’s budget-friendly XT lineup (spanning roughly $200-700 across the series). Measures more linear and has fewer/smaller cabinet resonances than its smaller sibling, the XT15, making it - by the reviewer’s own assessment - probably the better of the two based on data alone. Reasonably good bass output for the price and size, with an F3 of 63Hz. Horizontal radiation of about ±50° gives a respectable, enjoyable soundstage width. Takes well to EQ correction - the early-reflections directivity trend is decently linear, meaning tonal adjustments can meaningfully improve the sound. Provides usable, respectable volume when paired with a subwoofer crossover, even though it isn’t intended to play extremely loud on its own. Measured bass extension of 75Hz (-3dB), with a measured sensitivity of 86dB.
Cons: Notably bright treble, elevated roughly 1-5dB above the midrange depending on frequency - a characteristic shared across the whole Polk XT lineup, requiring either EQ or toe-out to tame. Small resonances appear around 300Hz and 800Hz, with some of that energy leaking from the port area. Vertical listening window is narrow - best kept close to the tweeter axis, with only a couple of degrees of tolerance above or below before the sound changes. Still needs a subwoofer for real low-end extension despite the decent F3. Overall linearity isn’t state-of-the-art flat, and while the reviewer found it pleasant, some artificial brightness remains even after basic EQ correction in the crossover region.
