Short answer: the Technics SB-C700, if you are buying new. The Definitive Technology Demand D11 measures as well as it (#59 vs #60 of 134 bookshelf speakers, 4.0/5 vs 4.0/5) but is discontinued, so only consider it used; the Technics SB-C700 is still sold new at $1,699.
Buy the Technics SB-C700, since the Definitive Technology Demand D11 is discontinued and only worth hunting down used.

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.

Definitive Technology Demand D11: $999 per pair Discontinued Amazon eBay
Pros: CEA2034 spinorama shows a mostly flat, well-controlled response: close to class-leading if not for one narrow resonance. Distortion is well controlled and the deep cabinet lets it play loud without bottoming out except on the deepest bass content. Cabinet construction and finish are a clear step above budget speakers. Measured bass extension of 60.1Hz (-3dB), with a measured sensitivity of 87dB.
Cons: A narrow but real ~600Hz jaggy shows up consistently in on-axis and off-axis measurements. Horizontal directivity is uneven because of the offset tweeter position, giving the left and right channels slightly different off-axis energy. There’s a low-frequency rattle/noise at very deep bass levels the reviewer called “horrendous.” Discontinued; the Demand series has moved on to newer models.
