Arendal 1961 Monitor vs Boston Acoustics A25

Last updated: August 24, 2026

Short answer: the Arendal 1961 Monitor for better sound quality, the Boston Acoustics A25 for the lower price. The Arendal 1961 Monitor ranks #8 of 74 bookshelf speakers at $1150. The Boston Acoustics A25 ranks #32 at $299.98, $850.02 cheaper.

What the Arendal 1961 Monitor offers: A physically robust build the reviewer calls “a little bit of a tank,” delivering low compression, low distortion, and overall really good neutrality - one of the reviewer’s top 10 picks under $1,500 across roughly 250 speakers tested. Works well both as home theater mains and as surrounds. Independent ASR Klippel measurements corroborate the low-distortion finding: THD at 86dB SPL/1m stays well below the reviewer’s audibility threshold, and even at 96dB SPL/1m it stays “far better than most bookshelves” thanks to the built-in high-pass filter that protects the woofers. Watch for: Bass rolls off around 70-80Hz, so it cannot be used as full-range mains for music without a subwoofer, and a sub is recommended for home theater use as well. Vertical radiation window is narrow, typical of MTM (mid-tweeter-mid) layouts - tighter than a standard two-way’s roughly ±20° - so a second home theater row sitting above or below the tweeter axis will hear a noticeably different tonal balance. ASR’s CEA2034 measurements show the response is elevated above 2kHz with resonant peaks around 3kHz and 9kHz, leading the reviewer to predict it will “likely sound bright.” Those same resonances show up as lingering ridges in the cumulative spectral decay (waterfall) at 96dB SPL/1m.

What the Boston Acoustics A25 offers: 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. Watch for: 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.

Buy the Arendal 1961 Monitor if sound quality matters more than the price. Buy the Boston Acoustics A25 if the price matters more than sound quality.
