Short answer: the Sonus Faber Lumina II Amator. It ranks #106 of 130 bookshelf speakers by sound quality at $2000; the ATC SCM19 ranks #119 and costs $3750, which makes this an easy call rather than a real tradeoff.
What the Sonus Faber Lumina II Amator offers: Solid bass extension for a bookshelf (F3 63Hz, F10 43Hz), reaching about 50Hz in-room. Decent sensitivity and wide, consistent horizontal dispersion (~60-70 degrees) - better directivity than expected for a two-way design. Gorgeous, luxury-grade cabinet design. Watch for: Very bright treble, running 3-6dB above the midrange depending on measurement angle - independently corroborated by other owners online, not just one reviewer’s opinion. Causes audible sibilance and a forward, grainy character. Notably the brightest of three Sonus Faber models Erin’s Audio Corner has tested, even brighter than the brand’s own Sonetto II G2. A mechanical resonance/ringing artifact shows up around 1kHz in measurements. Needs a subwoofer for anything below about 50Hz.
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 Sonus Faber Lumina II Amator. It ranks higher for sound quality than the ATC SCM19 and costs less, so the other one has nothing left to offer.
If sound quality matters at all to you, skip both of these and look higher up the 130 bookshelf speakers instead.
