Short answer: the Ascend Sierra 1 v2. It ranks #2 of 21 bookshelf speakers at $1000; the Arendal 1961 Monitor ranks #5 and costs $1150, so there is not much of a tradeoff to weigh.
On the Arendal 1961 Monitor side: A physically robust build the reviewer calls “a little bit of a tank,” delivering low compression, low distortion. The catch: Bass rolls off around 70-80Hz, so it cannot be used as full-range mains for music without a subwoofer.
The case for the Ascend Sierra 1 v2: Formaldehyde-free layered bamboo ply cabinet with a 1” dome tweeter over a 5.25” midwoofer. The tradeoff: F3 of 55Hz and F10 of 39Hz mean in-room extension tops out in the mid-40s Hz.
Buy the Arendal 1961 Monitor if the price matters more than the ranking. Buy the Ascend Sierra 1 v2 if the ranking matters more than the price.

The Two Speakers In Full
Arendal 1961 Monitor: $1150 Arendalsound
Pros: 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.
Cons: 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.

Ascend Sierra 1 v2: $1000 Ascendacoustics
Pros: Formaldehyde-free layered bamboo ply cabinet with a 1” dome tweeter over a 5.25” midwoofer, mated by a 4th-order acoustic crossover rather than a stock textbook design. In-room response is extremely linear - the reviewer called it “textbook” - a clear step up from the earlier V1, which had boxiness around 700Hz-1kHz and sibilance around 4-6kHz. Preference score of 8.4 with a subwoofer (6.8 without), which the reviewer calls topnotch. Wide, even horizontal radiation of about ±70° up to 6kHz. Better vertical directivity than its tweeter-to-woofer spacing would suggest, thanks to the steep 4th-order crossover slopes. No mechanical noise, port chuffing, or woofer bottoming even driven to 96dB/1m. In a three-way comparison against the Dynaudio Emit 20 and a Revel bookshelf model (all around $1,000/pair), measured as the most linear of the three and was the reviewer’s personal pick over both, despite the Dynaudio’s deeper bass and higher output capability. Independent ASR Klippel measurements corroborate Erin’s findings: superb off-axis response with only slight on-axis variations, and an in-room response the reviewer called “incredibly smooth and accurate - amazing for a non-DSP speaker.” Distortion above 200Hz at 86dB/1m is very low for the class.
Cons: F3 of 55Hz and F10 of 39Hz mean in-room extension tops out in the mid-40s Hz; the reviewer still recommends a subwoofer for full-range material. Diffraction dips appear around 3kHz and 5-6kHz, and the 1” dome tweeter starts beaming above roughly 6.7kHz, narrowing the soundstage radiation in the top octave - a straightforward consequence of dome size rather than a design flaw. At 96dB/1m the 5.25” midwoofer shows increased distortion in the midrange, likely tied to motor topology; high-passing to a subwoofer around 80Hz largely clears it up. Moderate sensitivity (~81-82dB average) with a 7-ohm minimum impedance. ASR’s power-sweep testing found response holds steady up to 96dB SPL/1m, but pushing to 102dB causes midbass below 400Hz to sag with distortion “through the roof” - a harder output ceiling than the 96dB tests alone suggest. Vertical directivity also narrows above about 1kHz, so the reviewer recommends staying at tweeter-axis height for best results.
