#49 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.

How it compares: Just above it: Definitive Technology Demand D11 - $700 cheaper, 2Hz higher bass extension (-3dB). Just below it: Dynaudio Contour 20i - $4051 more, 2.5Hz lower bass extension (-3dB).
