Short answer: the Ascend Acoustics HTM-200SE2. It ranks #7 of 178 bookshelf speakers by sound quality, rated 4.3/5, at $368. The Micca RB42 ranks #153, rated 2.3/5, at $159.99, $208.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Ascend Acoustics HTM-200SE2 is the better-sounding choice. 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 tradeoff: 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 case for the Micca RB42: Curved cabinet fit and finish look closer to a speaker costing three times as much. The tradeoff: CEA2034 spinorama shows significant peaks and valleys in the on-axis and listening-window response starting a few kHz up, with excess high-frequency energy the reviewer found fatiguing over time despite an initial impression of “detail.”
Buy the Ascend Acoustics HTM-200SE2. It is rated higher for sound quality, and saving $208.01 with the Micca RB42 does not make up for the sound-quality gap.

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. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
