Short answer: the Dynaudio Emit 20 for better sound quality, the KEF Q350 for the lower price. The Dynaudio Emit 20 ranks #72 of 122 bookshelf speakers at $1049. The KEF Q350 ranks #98 at $699, $350 cheaper.
What the Dynaudio Emit 20 offers: Two-way design with a 28mm Esotar soft dome tweeter (Hexis-damped) and an 18cm mid-woofer, using a first-order crossover on the tweeter and second-order on the woofer. Exceptional bass extension for a bookshelf speaker - reaches a clean, authoritative 40Hz in-room, rare enough that the reviewer says most listeners could skip a subwoofer for typical music. Very low distortion across the board, staying below 1% THD down to 40Hz at 86dB and below 3% even at 96dB - unusually clean bass performance where most two-way bookshelf speakers start rising in distortion around 80Hz. Wide, remarkably consistent horizontal directivity (about ±50-60°) that holds steady up to roughly 13kHz - rare for a speaker in this format, thanks to a beveled tweeter edge that acts as a mild waveguide. Excellent compression and dynamic-range linearity at the frequency extremes, actually showing slight bass enhancement rather than the sharp low-end compression common in similarly-sized bookshelf speakers. Watch for: A resonance around 600-800Hz gives snares and similar percussion a muffled, flat quality lacking impact - confirmed as originating in the woofer itself (isolated via measurements of the raw driver out of the cabinet), and attempts at constrained-layer damping didn’t resolve it. A peak around 4kHz adds a sharp, edgy quality to some male vocals. A roughly 5dB boost above 10kHz gives cymbals and hi-hats excess shimmer that can sound unnatural, especially pointed directly on-axis. Vertical dispersion shows two separate crossover-related notches (above and below the tweeter reference line around 5kHz) rather than the usual single one, a direct consequence of the shallow crossover slopes used on both drivers. Multitone distortion is elevated in the midrange, possibly due to the woofer’s magnet structure lacking a shorting ring. Best aimed slightly off-axis (about 10-15° of toe-out) to tame the excess high-frequency shimmer, rather than pointed straight at the listener.
What the KEF Q350 offers: CEA2034 spinorama shows a reasonably flat on-axis response with excellent directivity, aided by the coaxial Uni-Q driver. Vertical directivity is better than most non-coaxial two-way speakers, another benefit of the concentric design. Watch for: Two resonances at 700Hz and 1.2kHz show up on-axis, alongside an upper-bass boost. Predicted in-room response looks a bit boomy as a result. Distortion climbs substantially in the 100Hz-1kHz range at 96dB SPL/1m, with a distinct resonance-driven peak around 900Hz-1kHz at both test levels.
Buy the Dynaudio Emit 20 if sound quality matters more than the price. Buy the KEF Q350 if the price matters more than sound quality.
If sound quality matters at all to you, skip the KEF Q350. It ranks near the bottom of the 122 bookshelf speakers, so look higher up the list instead.
