Short answer: the Dynaudio Emit 20. It ranks #121 of 203 bookshelf speakers by sound quality (rated 3.6/5) at $1,049 and is still sold new; the KEF Q350 ranks #171 (rated 3.0/5) and is discontinued, so it is only an option used. The KEF Q350’s replacement, the KEF Q3 Meta, is rated 3.4/5.
The Dynaudio Emit 20 is the better-sounding, deeper-bass choice. 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. Its bass reaches about 54Hz before falling 3dB, against 70Hz for the KEF Q350. The tradeoff: 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.
The KEF Q350 is the more accurate choice. CEA2034 spinorama shows a reasonably flat on-axis response with excellent directivity, aided by the coaxial Uni-Q driver. Its measured preference score, a predictor of how neutral it sounds, is 5.25 against 4.22 for the Dynaudio Emit 20. Watch for: Two resonances at 700Hz and 1.2kHz show up on-axis, alongside an upper-bass boost.
Buy the Dynaudio Emit 20. It is rated higher for sound quality, and the KEF Q350 is discontinued, so it is only available used.

The Two Speakers In Full
Dynaudio Emit 20: $1,049.00 per pair Amazon eBay
Same family: the Dynaudio Emit 10 (smaller bookshelf, estimated 3.2/5), the Dynaudio Emit 30 (smaller floorstanding, rated 3.9/5), the Dynaudio Emit 50 (larger floorstanding, estimated 4.2/5) and the Dynaudio Emit 25C (center, estimated 3.7/5).
Pros: 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. Measured bass extension of 54Hz (-3dB), with a measured sensitivity of 83.5dB.
Cons: 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.

KEF Q350: $699.00 per pair Discontinued Amazon eBay
Newer model: the KEF Q3 Meta, ranked higher, rated 3.4/5.
Same family: the KEF Q150 (smaller bookshelf, rated 3.7/5), the KEF Q250c (smaller center, rated 3.9/5) and the KEF Q650c (larger center, rated 3.7/5).
Pros: 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. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 86dB.
Cons: 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. Discontinued.
