Short answer: the Dynaudio Emit 20. It ranks #75 of 130 bookshelf speakers by sound quality at $1049; the ATC SCM19 ranks #119 and costs $3750, so there is not much of a tradeoff to weigh.
What the Dynaudio Emit 20 offers: Two-way design with a 28mm Esotar soft dome tweeter (Hexis-damped) and an 18cm mid-woofer, using a first-order crossover on the tweeter and second-order on the woofer. Exceptional bass extension for a bookshelf speaker - reaches a clean, authoritative 40Hz in-room, rare enough that the reviewer says most listeners could skip a subwoofer for typical music. Very low distortion across the board, staying below 1% THD down to 40Hz at 86dB and below 3% even at 96dB - unusually clean bass performance where most two-way bookshelf speakers start rising in distortion around 80Hz. Wide, remarkably consistent horizontal directivity (about ±50-60°) that holds steady up to roughly 13kHz - rare for a speaker in this format, thanks to a beveled tweeter edge that acts as a mild waveguide. Excellent compression and dynamic-range linearity at the frequency extremes, actually showing slight bass enhancement rather than the sharp low-end compression common in similarly-sized bookshelf speakers. Watch for: A resonance around 600-800Hz gives snares and similar percussion a muffled, flat quality lacking impact - confirmed as originating in the woofer itself (isolated via measurements of the raw driver out of the cabinet), and attempts at constrained-layer damping didn’t resolve it. A peak around 4kHz adds a sharp, edgy quality to some male vocals. A roughly 5dB boost above 10kHz gives cymbals and hi-hats excess shimmer that can sound unnatural, especially pointed directly on-axis. Vertical dispersion shows two separate crossover-related notches (above and below the tweeter reference line around 5kHz) rather than the usual single one, a direct consequence of the shallow crossover slopes used on both drivers. Multitone distortion is elevated in the midrange, possibly due to the woofer’s magnet structure lacking a shorting ring. Best aimed slightly off-axis (about 10-15° of toe-out) to tame the excess high-frequency shimmer, rather than pointed straight at the listener.
What the ATC SCM19 offers: Harmonic distortion at 96dB SPL/1m stays generally low across the range aside from the spike tied to the 700-800Hz resonance. Sealed (unported) cabinet avoids port noise and resonance, and the extremely dense, heavy-duty enclosure (17.8kg/39lb each) reflects ATC’s pro-audio build standards. Watch for: Some stored energy resonance around 500-700hz, 4dB bump around 700hz. Not recommended for the price. CEA2034 spinorama and predicted in-room response both show a very uneven overall balance - a broad accentuation from midrange to treble paired with too little bass - along with directivity error. At 96dB SPL/1m, harmonic distortion tied to the 500-700Hz resonance rises to a level the reviewer says “should not be there.”
Buy the Dynaudio Emit 20. It ranks higher for sound quality than the ATC SCM19 and costs less, so there is no real case for the other one.
The ATC SCM19 is not a sound-quality pick. It sits near the bottom of the 130 bookshelf speakers; there are better options higher up.
