Short answer: the Boston Acoustics A25. It ranks #22 of 56 bookshelf speakers by sound quality at $299.98; the Dynaudio X14 ranks #32 and costs $1500, so there is not much of a tradeoff to weigh.
The case for the Boston Acoustics A25: CEA2034 spinorama is decent once you ignore a peak around 900Hz and a dip around 3kHz - directivity is good enough that the response can be EQed and won’t be too room-dependent. The tradeoff: A crazy port resonance and a tweeter with a steeper rolloff than the woofer both show up in the near-field driver measurements, creating the 900Hz peak and the crossover-region dip.
What the Dynaudio X14 gets right: 1” silk-dome tweeter and 5.7” magnesium-silicate-polymer woofer in a compact two-way stand-mount, rated at 85dB sensitivity. The catch: 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.
Buy the Boston Acoustics A25. It ranks higher for sound quality than the Dynaudio X14 and costs less, so there is no real case for the other one.

The Two Speakers In Full
Boston Acoustics A25: $299.98 Discontinued
Pros: CEA2034 spinorama is decent once you ignore a peak around 900Hz and a dip around 3kHz - directivity is good enough that the response can be EQed and won’t be too room-dependent. Cabinet fit and finish is well above its price class, and dynamics were strong with no distortion audible even at high volume on well-recorded material. Discontinued, but the reviewer suggests hunting for clearance pricing on remaining stock.
Cons: A crazy port resonance and a tweeter with a steeper rolloff than the woofer both show up in the near-field driver measurements, creating the 900Hz peak and the crossover-region dip. The rear port itself measured audibly distorted up close, though it wasn’t noticeable from normal listening distance in the reviewer’s room. Discontinued.

Dynaudio X14: $1500 Discontinued
Pros: 1” silk-dome tweeter and 5.7” magnesium-silicate-polymer woofer in a compact two-way stand-mount, rated at 85dB sensitivity.
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.
