Short answer: the Revel M16, for the flatter response. The Yamaha NS-800A is exceptionally well built, with no internal resonance in burst decay or impedance measurements, but a wide scoop from roughly 2kHz-10kHz gives a laidback, soft, low-attack character notably worse than the reviewer’s Audio First Fidelia reference in an A/B comparison. The M16 is flat on-axis from 200Hz to 10kHz, with distortion peaks around 80Hz and 350Hz.
Buy the Yamaha NS-800A new; the Revel Concerta2 M16 is no longer sold new, so it only makes sense as a used find.

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.

Yamaha NS-800A: $4,999.90 per pair The Music Room eBay
Pros: Exceptionally well-built cabinet with no internal resonance issues at all: confirmed clean in both burst decay and impedance measurements. Good, wide directivity (~75 degrees horizontal) that stays consistent enough to EQ successfully. Distortion is low, staying under 3% at 96dB, and dynamic range holds up well until right near its 102dB limit. A shallower, higher-frequency bass rolloff profile (F3 68Hz, F10 35Hz) means it can be placed closer to the wall (about a foot) without turning boomy, actually gaining bass presence rather than losing it. Measured bass extension of 68Hz (-3dB), with a measured sensitivity of 84.9dB.
Cons: A wide, roughly 2kHz-10kHz scoop in the upper-midrange/lower-treble gives it a laidback, soft, low-attack character: notably worse than the reviewer’s Audio First Fidelia reference in an A/B comparison. On top of that, treble breaks up badly above 10kHz, swinging up as much as 8dB: a significant, named flaw. Sounds inconsistently voiced as a result (bright on some material like cymbals and shakers, dull/laidback on vocals and instrument attack) until corrected with real parametric EQ (the reviewer needed a +2dB boost around 4.5kHz at Q0.5 plus taming the treble spike to bring it to life) combined with near-wall placement and 30-degree toe-out. Without that combination, it’s a tough sale for a $5000 bookshelf speaker.
