Short answer: the Ascend Sierra 1 v2 for better sound quality, the Dynaudio Emit M10 for the lower price. The Ascend Sierra 1 v2 ranks #3 of 71 bookshelf speakers at $1000. The Dynaudio Emit M10 ranks #43 at $800, $200 cheaper.
What the Dynaudio Emit M10 offers: CEA2034 spinorama shows impressive, headphone-level distortion through the midrange and tweeter at 86dB SPL, with a well-executed port that keeps resonance low below the crossover. 28mm soft dome tweeter and 14cm MSP mid/bass driver. Watch for: Tuned toward a mild showroom sound with boosted upper bass and treble and a recessed midrange - the reviewer prefers speakers that get the 100Hz-3kHz range right, which this doesn’t. His verdict: cheaper speakers deliver much more balanced tonality, so he wouldn’t buy it for himself.
What the Ascend Sierra 1 v2 offers: Formaldehyde-free layered bamboo ply cabinet with a 1” dome tweeter over a 5.25” midwoofer, mated by a 4th-order acoustic crossover rather than a stock textbook design. In-room response is extremely linear - the reviewer called it “textbook” - a clear step up from the earlier V1, which had boxiness around 700Hz-1kHz and sibilance around 4-6kHz. Preference score of 8.4 with a subwoofer (6.8 without), which the reviewer calls topnotch. Wide, even horizontal radiation of about ±70° up to 6kHz. Better vertical directivity than its tweeter-to-woofer spacing would suggest, thanks to the steep 4th-order crossover slopes. No mechanical noise, port chuffing, or woofer bottoming even driven to 96dB/1m. In a three-way comparison against the Dynaudio Emit 20 and a Revel bookshelf model (all around $1,000/pair), measured as the most linear of the three and was the reviewer’s personal pick over both, despite the Dynaudio’s deeper bass and higher output capability. Independent ASR Klippel measurements corroborate Erin’s findings: superb off-axis response with only slight on-axis variations, and an in-room response the reviewer called “incredibly smooth and accurate - amazing for a non-DSP speaker.” Distortion above 200Hz at 86dB/1m is very low for the class. Watch for: F3 of 55Hz and F10 of 39Hz mean in-room extension tops out in the mid-40s Hz; the reviewer still recommends a subwoofer for full-range material. Diffraction dips appear around 3kHz and 5-6kHz, and the 1” dome tweeter starts beaming above roughly 6.7kHz, narrowing the soundstage radiation in the top octave - a straightforward consequence of dome size rather than a design flaw. At 96dB/1m the 5.25” midwoofer shows increased distortion in the midrange, likely tied to motor topology; high-passing to a subwoofer around 80Hz largely clears it up. Moderate sensitivity (~81-82dB average) with a 7-ohm minimum impedance. ASR’s power-sweep testing found response holds steady up to 96dB SPL/1m, but pushing to 102dB causes midbass below 400Hz to sag with distortion “through the roof” - a harder output ceiling than the 96dB tests alone suggest. Vertical directivity also narrows above about 1kHz, so the reviewer recommends staying at tweeter-axis height for best results.
Buy the Dynaudio Emit M10 if the price matters more than sound quality. Buy the Ascend Sierra 1 v2 if sound quality matters more than the price.
