Short answer: the Dynaudio Emit 20, if you are buying new. The Revel Concerta2 M16 ranks higher than it (#51 vs #75 of 131 bookshelf speakers, 4.1/5 vs 3.6/5) but is discontinued, so only consider it used; the Dynaudio Emit 20 is still sold new at $1,049.
The case for the Revel Concerta2 M16: CEA2034 spinorama shows an on-axis response that’s essentially flat from 200Hz to 10kHz, with some bass boost around 100Hz. The catch: Harmonic distortion shows a notable peak around 80Hz and a sharp spike around 350Hz, plus the woofer appears to get a bit unhappy right before handing off to the tweeter.
The case for the Dynaudio Emit 20: 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. 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.
Buy the Dynaudio Emit 20, since the Revel Concerta2 M16 is discontinued and only worth hunting down used.

Revel Concerta2 M16: $600 per pair used (about) Discontinued eBay
Pros: CEA2034 spinorama shows an on-axis response that’s essentially flat from 200Hz to 10kHz, with some bass boost around 100Hz. Predicted in-room response is very nice, with just extra bass and a bit of roll-off above 20kHz - the reviewer calls it “nice!” Distortion is well controlled through most of the range at both test levels. Measured bass extension of 60.1Hz (-3dB).
Cons: Harmonic distortion shows a notable peak around 80Hz and a sharp spike around 350Hz, plus the woofer appears to get a bit unhappy right before handing off to the tweeter. Cumulative spectral decay (waterfall) shows some lingering resonances in the 300Hz-1kHz region. The reviewer cautions not to over-cover the cabinet/grille area with thin fabric, as it can audibly affect the top-end response. Discontinued.

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.
