#21 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.

How it compares: Just above it: Dayton Audio OPAL1 - $739 more, 9.3Hz lower bass extension (-3dB). Just below it: JBL Studio 530 - $99 more.
