Short answer: the Dynaudio Contour 20i for better sound quality, the Polk Monitor XT20 for the lower price. The Dynaudio Contour 20i ranks #60 of 125 bookshelf speakers at $5750. The Polk Monitor XT20 ranks #88 at $279, $5471 cheaper.
What the Polk Monitor XT20 offers: 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. Watch for: 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.
What the Dynaudio Contour 20i offers: Two-way design with a 1.125” Esotar2i silk dome tweeter and a 7” magnesium silicate polymer woofer in a vented enclosure. A shallow bass rolloff profile lets it sit closer to a wall (about 1-2 feet worked best in testing) without becoming boomy, and makes subwoofer integration comparatively easy. Very wide horizontal radiation (about ±70° through the midrange) gives an enveloping, spacious sound in a suitably sized room. On-axis response holds within about ±3dB overall and ±1.5dB through the midrange. Attractive build quality with a distinctive metal front baffle and gloss finish options. Long-term compression stays good up to 96dB, and short-term compression is within about 0.5dB at that same level. Watch for: Notably room-dependent: sounds too bright in the lower treble in smaller rooms with close sidewalls, needing sidewall absorption to sound neutral, while performing better in larger or more open rooms without that treatment. A roughly 2dB lift in the lower treble combined with wide dispersion means more energy reflecting off sidewalls than some listeners will prefer. Relatively low sensitivity (about 82.5dB measured). Unusually sensitive to amplifier output impedance - high-output-impedance amps like tube or SET designs introduce up to a 2dB dip in the midrange, making the sound more mellow rather than “warmer,” the opposite of what many tube-amp buyers expect. Elevated harmonic and multitone distortion around 700Hz, which the reviewer attributes to typical cone-edge/surround behavior common across many driver brands, though it stands out on the measurement graphs. An upper-midrange dip around 2kHz can reduce attack and clarity on vocals and brass instruments. Vertical listening window is fairly narrow (roughly -20° to +30°) - moving outside that range causes a noticeable tonal shift, unlike coaxial designs that tolerate more vertical movement.
Buy the Polk Monitor XT20 if the price matters more than sound quality. Buy the Dynaudio Contour 20i if sound quality matters more than the price.
