Short answer: the MoFi SourcePoint 10 on measured sound quality, the ATC SCM19 on price. The MoFi SourcePoint 10 ranks #26 of 130 bookshelf speakers at $3795. The ATC SCM19 ranks #119 at $3750, $45 cheaper.
What the MoFi SourcePoint 10 offers: Andrew Jones-designed concentric/coincident driver delivers best-in-class sound power and early-reflections directivity in the reviewer’s testing - a genuine “point source” design. Vertical and horizontal radiation patterns closely match each other (about ±50° horizontal, ±30-40° vertical), a hallmark benefit of a well-executed concentric driver. Distortion stays low - under 1% above 100Hz at 86dB, and under 3% up to 100Hz even at 96dB, better than the reviewer expected from a low-excursion waveguide-loaded woofer. Surprisingly strong dynamic capability with little audible compression at both low and high volume. Widely spaced (about 11 feet apart) with roughly 15° of toe-out produced a huge, expansive soundstage without significant loss of imaging precision. Solidly built cabinet (about 40 lbs, heavily braced) minimizes cabinet resonance. Watch for: Like virtually all coincident designs, sounds notably bright pointed directly on-axis due to a deliberate treble lift (meant to compensate for the 28mm tweeter’s earlier beaming versus a typical 25mm/1” tweeter) combined with a diffraction dip/peak from the waveguide edge; needs about 15° of toe-out to sound neutral, and even then benefits from an extra 1-2dB of treble EQ. Toeing out further (to 30°) flattens the treble further but introduces a dip in the midrange-to-tweeter crossover region - there’s no single toe-out angle that fixes everything at once. F3 of 56Hz and F10 of 38Hz (about 40Hz in-room) mean genuine deep bass is limited; the reviewer would pair it with a sealed 10” or 12” subwoofer for regular daily listening. Bass extension and cabinet placement trade off against midrange cleanliness: placing it close to a wall for more bass risks a wall-bounce suckout in the midrange (roughly 200-500Hz depending on distance). Not perfectly time-aligned between tweeter and woofer (about 0.4ms delta), an inherent limitation of passive coincident drivers versus actively time-corrected designs. Some resonances appear in measurements, likely port-related. Minimum impedance around 6.4 ohms with EPDR near 3 ohms, so the reviewer recommends sticking with a 4-ohm-rated amplifier to be safe.
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 MoFi SourcePoint 10 when sound quality outweighs the price for you, and the ATC SCM19 when the price outweighs sound quality instead.
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.
