Short answer: the ELAC Debut 2.0 B5.2, because its broad error is the easier one to correct. Good horizontal directivity means the off-axis curves track the on-axis response closely, so the broad +3dB step beginning around 1.5kHz responds predictably to EQ. The Dynaudio X14’s CEA2034 spinorama shows an uneven on-axis response from the lack of a waveguide, plus a port resonance that boosts the lower midrange and imperfect crossover matching.

ELAC Debut 2.0 B5.2: $269.00 per pair Amazon eBay
Pros: 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. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 83dB.
Cons: 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.

Dynaudio X14: $1,500 per pair Discontinued eBay
Pros: 1” silk-dome tweeter and 5.7” magnesium-silicate-polymer woofer in a compact two-way stand-mount, rated at 85dB sensitivity. Measured bass extension of 67.4Hz (-3dB), with a measured sensitivity of 82dB.
Cons: CEA2034 spinorama shows an uneven on-axis response from the lack of a waveguide to control tweeter beam width, plus a port resonance that boosts the lower midrange and imperfect crossover matching between the drivers. Too much energy in the lower and upper treble reads as bright, and directivity narrows at higher frequencies rather than staying controlled. The reviewer’s verdict: out of the box, the objective performance isn’t that great, though EQ can make it a satisfying speaker. Discontinued.
