Short answer: the Ascend Acoustics Sierra 1 v2 on measured sound quality, the Ascend Acoustics HTM-200SE2 on price. The Ascend Acoustics Sierra 1 v2 ranks #3 of 168 bookshelf speakers, rated 4.7/5, at $1,000. The Ascend Acoustics HTM-200SE2 ranks #7, rated 4.3/5, at $368, $632 cheaper.
The Ascend Acoustics Sierra 1 v2 is the more accurate, deeper-bass pick. 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. Its measured preference score, a predictor of how neutral it sounds, is 6.65 against 4.98 for the Ascend Acoustics HTM-200SE2. Its bass reaches about 55Hz before falling 3dB, against 87.9Hz for the Ascend Acoustics HTM-200SE2. The tradeoff: 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.
The case for the Ascend Acoustics HTM-200SE2: High-quality manufacturer NFS data shows 0.385dB on-axis average absolute deviation, 0.428 listening-window smoothness, and unusually even 80-degree dispersion in both planes. The catch: Limited bass is the main tradeoff, measuring 87.9Hz at -3dB, 71.8Hz at -6dB, and 51.3Hz at -12dB; its preference score falls to 4.98 without a subwoofer.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.

Same family: the Ascend Acoustics Sierra-2EX V2 (larger bookshelf, rated 4.3/5), the Ascend Acoustics Sierra-LX (larger bookshelf, rated 4.3/5), the Ascend Acoustics Sierra Titan Tower (floorstanding, rated 4.4/5) and the Ascend Acoustics Sierra Horizon V2 (center, estimated 4.3/5). See every Ascend Sierra generation.
Pros: 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. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 81.5dB.
Cons: 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.

Ascend Acoustics HTM-200SE2: $368 per pair Ascend Acoustics $368 eBay
Same family: the Ascend Acoustics CBM-170 SE2 (smaller bookshelf, rated 3.8/5) and the Ascend Acoustics CMT-340 SE2 (larger bookshelf, rated 4.4/5). See every Ascend CBM, HTM and CMT generation.
Pros: High-quality manufacturer NFS data shows 0.385dB on-axis average absolute deviation, 0.428 listening-window smoothness, and unusually even 80-degree dispersion in both planes. The compact sealed cabinet is easy to place, while the preference score reaches 7.90 with a subwoofer. Measured bass extension of 87.9Hz (-3dB), with a measured sensitivity of 86.0dB.
Cons: Limited bass is the main tradeoff, measuring 87.9Hz at -3dB, 71.8Hz at -6dB, and 51.3Hz at -12dB; its preference score falls to 4.98 without a subwoofer. The 3.62 sound-power directivity-index standard deviation is respectable rather than exceptional, and the small woofers limit deep-bass output.
