Short answer: the Revel Concerta2 M16. It ranks #41 of 105 bookshelf speakers by sound quality at $600; the Technics SB-C700 ranks #49 and costs $1699, so there is not much of a tradeoff to weigh.
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.
On the Technics SB-C700 side: 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. Watch for: 85dB sensitivity paired with a 4-ohm nominal impedance wants a fairly capable amplifier.
Buy the Revel Concerta2 M16. It ranks higher for sound quality than the Technics SB-C700 and costs less, so there is no real case for the other one.

Revel Concerta2 M16: about $600 used
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.
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.

Technics SB-C700: $1,699.00 Value Electronics USA Tube Audio
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 spdi_stddev (3.09) is tight for the passive-large tier. Die-cast aluminum chassis and a high-gloss convex “Entasis form” cabinet with side panels up to 42mm thick for extra rigidity.
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 $1,699.99/pair, some in the ASR community have questioned the value proposition against similarly-measuring alternatives at lower prices.
