#27 Neumi Silk 4: $199.99 Amazon eBay
Pros: 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.
Cons: 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.
How it compares: Just above it: Polk Audio XT15 - $21 cheaper, 3.4Hz higher bass extension (-3dB). Just below it: Dayton Audio OPAL1 - $839 more, 6.9Hz lower bass extension (-3dB).
