Short answer: the Revel M16, unless you want true point-source geometry. The Technics SB-C700’s coincident Phase Precision Driver mounts a 1.9cm dome tweeter at the acoustic center of a 16cm flat-diaphragm woofer, but its 85dB sensitivity and 4-ohm nominal impedance want a capable amplifier. The M16’s on-axis response is essentially flat from 200Hz to 10kHz, though harmonic distortion peaks around 80Hz and spikes around 350Hz.
Buy the Technics SB-C700 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.

Technics SB-C700: $1,699.00 per pair Value Electronics USA Tube Audio eBay
Pros: Distinctive coincident “Phase Precision Driver”: a 1.9cm dome tweeter mounted at the exact acoustic center of a 16cm flat-diaphragm carbon-fiber/honeycomb-sandwich woofer, giving true point-source geometry. Directivity is unusually symmetric front-to-back and top-to-bottom (both horizontal and vertical average exactly 60°) and off axis sound tracks the on axis response unusually consistently for a large bookshelf speaker. Die-cast aluminum chassis and a high-gloss convex “Entasis form” cabinet with side panels up to 42mm thick for extra rigidity. Measured bass extension of 85.0Hz (-3dB).
Cons: 85dB sensitivity paired with a 4-ohm nominal impedance wants a fairly capable amplifier. Bass extension is shallow relative to its 6.5”-class woofer at -3dB (85.0Hz), though it reaches a more usable 40.5Hz at -10dB: a fairly steep low-end rolloff shape once past the reference band. At $1699/pair, some in the ASR community have questioned the value proposition against similarly-measuring alternatives at lower prices.
