Ascend Acoustics HTM-200SE2: $368 per pair Ascend Acoustics eBay
Same family: the Ascend CBM-170 SE2 (smaller bookshelf, rated 3.8/5) and the Ascend Acoustics CMT-340 SE2 (larger bookshelf, rated 4.4/5).
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.
