Danish loudspeaker company Dynaudio is one of the few manufacturers that is both a supplier of raw drivers, and a provider of complete, high-end loudspeakers for consumer and professional audio. (They also supply drivers and systems for automobiles.) As such, their loudspeakers have the advantage of incorporating made-in-house, made-to-spec drivers, unlike some other manufacturers who buy drivers from other sources and put them in a cabinet (sometimes also bought from outside vendors). But that's just part of the story. The most striking immediate aspect of Dynaudio speakers is their superb craftsmanship--as exemplified by the limited edition Sapphire floorstanding loudspeaker (suggested retail price: $16,500 per pair).

The Sapphire is stunning in design, with trapezoidal front, side and top surfaces that, appropriately, give it a faceted gem-like appearance. Measuring 53 inches high by 13 inches wide and nearly 13 inches deep, it's tall and slim, a beautiful Danish model (OK, I couldn't resist the analogy). The 88-pound speaker is available in a choice of Ivory, Amber, Bordeaux and Mocca real wood high-gloss veneer finishes that are impeccable.

Beauty isn't just skin-deep here. (Well, maybe I'm a little obsessive but I find well-made drivers and high-quality speaker engineering beautiful.) The three-way, bass-reflex-enclosure Sapphire incorporates two eight inch woofers made using Dynaudio's light, rigid magnesium silicate polymer (MSP) membrane, a six inch MSP midrange driver mounted in an acoustically isolated sub-enclosure, and a one inch Esotar coated-fabric dome tweeter. The woofers have three inch aluminum voice coils on Kapton formers and high-power Neodymium double-magnet systems, and the tweeter features a CNC-machined metal housing, a specially shaped internal damping chamber and a lightweight aluminum voice coil.

The Sapphire has a frequency response of 30Hz - 25kHz, 88dB sensitivity and a nominal impedance of 4 ohms. The crossover points are at 450Hz and 2.2kHz. As you'd expect, top-quality internal components and wiring are used, and the enclosure is solid to say the least.
