Short answer: the AsciLab C6B. It ranks #7 of 131 bookshelf speakers by sound quality at $1145; the Arendal 1961 Monitor ranks #8 and costs $1150, so there is not much of a tradeoff to weigh.
What the Arendal 1961 Monitor gets right: A physically robust build the reviewer calls “a little bit of a tank,” delivering low compression, low distortion. Set against that: Bass rolls off around 70-80Hz, so it cannot be used as full-range mains for music without a subwoofer.
On the AsciLab C6B side: Two-way design pairing a 1” aluminum ceramic dome tweeter on a large waveguide with a 6” aluminum ceramic cone woofer. Set against that: Bass rolls off around 50Hz in-room (F3 54Hz, F10 35Hz), so a subwoofer is needed for real extension below that.
Buy the AsciLab C6B. It ranks higher for sound quality than the Arendal 1961 Monitor and costs less, which settles it without a real tradeoff to make.

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

AsciLab C6B: $1145 Ascilab eBay
Pros: Two-way design pairing a 1” aluminum ceramic dome tweeter on a large waveguide with a 6” aluminum ceramic cone woofer, crossed over at 1.1kHz, plus a rear passive radiator. Unusual trait: horizontal radiation actually widens at higher frequencies instead of narrowing like most two-way designs, which keeps image focus and soundstage depth consistent whether you toe the speakers in or out (5-10° off-axis was the sweet spot in testing). Vertical radiation also stays wide straight through the 2kHz crossover region, so the sound doesn’t collapse when standing up - unusual at this price. CA2034 measurements show strong on-axis linearity, listening window, early reflections, and directivity. Midrange and tweeter distortion stay very low even at 96dB, holding up against a $5,900 Arendal speaker in that regard despite roughly a 5x price gap. At $935 (about $1,135 shipped to the US), the reviewer calls it the best-value bookshelf speaker he’s tested, rivaling speakers 2-5x the price.
Cons: Bass rolls off around 50Hz in-room (F3 54Hz, F10 35Hz), so a subwoofer is needed for real extension below that. Low-frequency harmonic distortion increases substantially at 96dB versus 86dB, though it’s second-order and less audible than it looks on paper. Minimum impedance dips to 2.6 ohms (EPDR as low as 1.2 ohms), so it wants an amplifier comfortable driving 4-ohm loads, ideally 100W or more. At 102dB, compression noticeably eats into midrange, bass, and some treble output. Shipping to the US adds roughly $200 on top of the $935 price. Against the reviewer’s reference Audiofirst Fidelia at a similar price, has slightly less lower-midrange body (about 1dB difference) and a smaller perceived soundstage size.
