Short answer: the Ascend Acoustics CMT-340 SE2. It ranks #23 of 130 bookshelf speakers by sound quality at $798; the MoFi SourcePoint 10 ranks #26 and costs $3795, so there is little reason to consider the other one.
What the Ascend Acoustics CMT-340 SE2 offers: High-quality manufacturer Klippel NFS data shows 0.295dB on-axis average absolute deviation, 0.531 listening-window smoothness, and a strong 7.17 preference score with a subwoofer. Its dual 6.5-inch woofers, 92dB anechoic sensitivity, and 240W continuous power rating support high output and dynamics. Watch for: Bass rolls off early for the cabinet size, measuring 77.6Hz at -3dB, 64.5Hz at -6dB, and 48.3Hz at -12dB; the preference score without a subwoofer is only 4.51. The 4.35 sound-power directivity-index standard deviation also indicates more off-axis variation than the strongest designs, and the rear port needs placement clearance.
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.
Buy the Ascend Acoustics CMT-340 SE2. It ranks higher for sound quality than the MoFi SourcePoint 10 and costs less, so there is no real case for the other one.
