Short answer: the Ascend Acoustics HTM-200SE2 if sound quality matters most, the ELAC Debut 2.0 B5.2 if price matters most. The Ascend Acoustics HTM-200SE2 ranks #7 of 87 bookshelf speakers at $368. The ELAC Debut 2.0 B5.2 ranks #47 at $269, $99 cheaper.
What the Ascend Acoustics HTM-200SE2 offers: 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 7.11 with a subwoofer. Watch for: 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 4.20 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.
What the ELAC Debut 2.0 B5.2 offers: Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Erin demonstrated that a single high-shelf filter centered near 1.6kHz, about -2dB with Q near 2, substantially improves linearity. Moderate roughly +/-50-60 degree horizontal coverage balances room interaction and image focus. The front port makes close-to-wall placement practical. Erin measured F3 near 60Hz and F10 near 40Hz, useful extension for a compact 5.25-inch two-way. Harmonic distortion is mostly below 1% at 86dB/1m, and low-frequency distortion is better than its size might suggest. Compact cabinet and inexpensive pair pricing make it a workable EQ-assisted desktop or small-room system. Watch for: Erin measured a broad +3dB step beginning around 1.5kHz; the resulting elevated upper range sounds tonally uneven even though it is not a narrow, sharp resonance. Native response spans roughly -2.6 to +4dB around the mean, so this is not a neutral speaker without correction. Sensitivity is only about 83dB after correcting the shelf, demanding materially more amplifier voltage than ELAC’s 86dB specification implies. Vertical response changes substantially outside roughly +/-10 degrees of tweeter height. Dynamic compression is the larger limitation: at the highest sweep level it loses roughly 1-1.5dB through the midrange, and even the 86dB trace shows unusual nonlinearity that may involve crossover heating. At about 96dB, multitone distortion rises audibly around 600Hz; an 80-120Hz subwoofer crossover helps but does not turn it into a high-output design. Erin recommends the larger B6.2 instead when EQ is unavailable.
