Short answer: the Revel M105, clearly. Its spinorama is essentially flat on-axis with only a small 5kHz peak, a smooth listening window and clean waterfall decay, though its low nominal impedance demands a capable amplifier. The Boston Acoustics A25 is decent once you ignore a peak around 900Hz and a dip around 3kHz, but a crazy port resonance and a tweeter that rolls off faster than its woofer create exactly those problems.
Buy the Revel M105 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.

Revel M105: $1,500 per pair Discontinued eBay
Pros: CEA2034 spinorama shows an essentially flat on-axis response with only a small 5kHz peak, a smooth listening window, and clean waterfall decay. Wide horizontal dispersion gives flexibility with toe-in. The reviewer called it reference-quality performance with minor EQ correction applied. Measured bass extension of 63Hz (-3dB), with a measured sensitivity of 85dB.
Cons: Low nominal impedance demands a capable amplifier that can handle low-impedance loads. Bass distortion runs high in the 80-250Hz range from woofer displacement, and maximum output is limited compared to larger designs. Discontinued.

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.
