Short answer: the Technics SB-C700 for point-source geometry, the Yamaha NS-800A for a cleaner cabinet. The SB-C700 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 NS-800A has no internal resonance issues yet a wide 2kHz-10kHz scoop, and it costs $4,999.90 against $1,699.
Buy the Technics SB-C700. Both are rated the same for sound quality, and it costs $3,300.90 less than the Yamaha NS-800A.

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.

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.
