Short answer: the Dynaudio Emit 20. It ranks #75 of 130 bookshelf speakers by sound quality; the Mission LX-3 MKII ranks #80.

Dynaudio Emit 20 vs Mission LX-3 MKII

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 Mission LX-3 MKII offers: A large affordable standmount with a 6.5-inch woofer, 88dB rated sensitivity and useful bass. ASR measured 48Hz estimated in-room extension, a controlled Q of 0.60, a 5.52 subwoofer-assisted preference score and reasonable +/-55-degree horizontal coverage. Watch for: On-axis smoothness of 0.217 and predicted in-room smoothness of 0.344 reveal clear response unevenness, with a -0.46dB-per-octave downward tilt. The 345mm-tall, 8.4kg cabinet is bulky and current US availability is limited.
