Short answer: the Arendal 1961 Monitor for better sound quality, the Neumi Silk 4 for the lower price. The Arendal 1961 Monitor ranks #8 of 87 bookshelf speakers at $1150. The Neumi Silk 4 ranks #33 at $199.99, $950.01 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 Neumi Silk 4 offers: A 4” midwoofer paired with a 1” dome tweeter and waveguide, with a second-order crossover, achieving an impressively high preference score of 4.4 for the price. Distortion stays below 1% up to about 120Hz and below 3% above roughly 50-60Hz at 86dB. High-frequency compression is surprisingly good - better than some speakers costing 2-3x as much - and at 96dB/1m for a pair, output still reaches about 93dB at 3 meters, plenty loud for most listeners. F3 of 83Hz and F10 of 55Hz with in-room extension to about 70Hz. Takes very well to EQ correction, and the reviewer provides a specific fix (a notch around 650Hz, Q of about 6) that cleans up its main resonance. Watch for: Very low sensitivity (measured 82.6dB), meaning it isn’t suited for large rooms, far-field listening, or high volume. A resonance around 650Hz (likely port- or cabinet-related) creates an audible 1-2dB midrange thickness/boxiness on certain tracks, tied to a probable baffle-step compensation shortfall - about 1dB more energy in the midrange from the factory would likely have resolved it. Multitone distortion becomes audible around the same 600Hz-1kHz region at 96dB. Horizontal radiation narrows to about ±50° with the waveguide, on the narrower side of what the reviewer prefers. A diffraction-related dip around 5kHz at 5° below the tweeter axis creates a small hole in the response if placed on a desk below ear level. Nominal impedance of about 6 ohms with a low sensitivity means it benefits from a subwoofer pairing (the reviewer suggests an 80Hz crossover) for a complete small-room or surround setup.
Buy the Arendal 1961 Monitor if sound quality matters more than the price. Buy the Neumi Silk 4 if the price matters more than sound quality.
