Short answer: the Boston Acoustics A25, and it is far cheaper. The Dynaudio X14 pairs a 1” silk-dome tweeter with a 5.7” magnesium-silicate-polymer woofer and rates 85dB sensitivity, but its spinorama shows an uneven on-axis response from the lack of a waveguide, a port resonance that boosts the lower midrange, and imperfect crossover matching. The A25 has its own flaws, a 900Hz peak and port resonance, but costs $1,200.02 less.
Buy the Boston Acoustics A25 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.

Boston Acoustics A25: $299.98 per pair Discontinued eBay
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. Measured bass extension of 90Hz (-3dB), with a measured sensitivity of 85dB.
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: $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.
