Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Dynaudio X14 is the better pick: it ranks #62 of 90 bookshelf speakers by sound quality (rated 2.9/5), against #71 (rated 2.4/5) for the KEF Q100. Both are rated below 3.0/5 among the 90 bookshelf speakers; for better sound, the Philharmonic Ceramic Mini ranks #2 at $900.
Buy the Dynaudio X14 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Philharmonic Ceramic Mini instead.

The Two Speakers In Full
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.

KEF Q100: $550 per pair Discontinued eBay
Newer model: the KEF Q1 Meta, ranked higher, rated 3.6/5.
Pros: 5.25” Uni-Q coaxial driver keeps the tweeter and woofer point-source aligned for consistent imaging. 86dB sensitivity is reasonably easy to drive. Measured bass extension of 85Hz (-3dB), with a measured sensitivity of 85dB.
Cons: CEA2034 spinorama shows broad, audible deviations from flat rather than narrow peaks: a lift from 700Hz-1.5kHz and again from 5kHz up, plus a cancellation notch around 1.4kHz from port/cabinet interaction. Bass sensitivity drops to about 80dB and impedance falls below 4 ohms in the bass, demanding a capable amplifier. The reviewer heard boomy, buzzing bass that improved somewhat with the port plugged, and could not recommend it, calling the famous reputation more about looks than sound. Discontinued.
