Quantum 1009 S

Floorstanding speaker, 3-way bass reflex configuration with double bass driver

  • An audiophile and visual masterpiece: Absolute high-end components, perfectly tuned and coordinated and presented in a stylish case
  • 30 mm tweeter with a particularly lightweight membrane made of semi-crystalline polymer (PTFE) for maximum efficiency
  • Klippel-optimized 170 mm "Controlled Flexing Cone" woofer with a ceramic-aluminium sandwich membrane for perfect three-dimensionality
  • Two 200 mm ceramic-alumimium cone subwoofers for a precise, dynamic bass foundation
  • Sturdy MDF enclosure with a low-resonance baffle and double-walled side panel structure with non-constant material thickness


Floorstanding speaker, 3-way bass reflex configuration with double bass driver

Audiophile components and technical innovation are the hallmarks of this top-of-the-range model in the Quantum 1000 S series. This flagship speaker, which is available in a black or white high-gloss finish, has been redesigned and the fitted wooden side panels featured by its predecessor have been omitted.
Besides the excellent quality workmanship and material used, as well as the speaker´s simple, elegant design, the focal point of the Quantum 1009 S is clearly on its acoustic performance. Two 170 mm chassis cater for a powerful low-frequency range, while the midrange driver with its "Controlled Flexing Cone" guarantees a degree of spatiality that is well above-average. The high-end tweeter with its wide surround ensures an optimum performance in the treble range.

What do trade magazines say about this product?

Gold-plated bi-wiring terminal

The bi-wiring connector panel with solid, encapsulated screw terminals is also perfectly suited to high-quality large gauge cables. The generously dimensioned cable bridges forward every signal loss-free to the loudspeaker.

Perfect acoustic decoupling

Solid all-metal spikes for perfect acoustic decoupling from the floor area. The spikes are height adjustable so as to compensate for uneven areas.

Highlights


Woofer / midrange
  • Sophisticated voice coil ventilation for a particularly high degree of resilience
  • High cone rigidity ensured by inverse ceramic/aluminium dust caps for the woofer and midrange
  • Distortion-optimised magnet system with double induction rings and stray field optimisation
  • Well-ventilated die-cast basket to prevent turbulence and compression effects
  • Controlled Flexing Cone: New cone geometry for controlled projection of wave fronts in the mid range, and with it the capability to reproduce a greater bandwidth 16 and 20 cm woofers with particularly flat cone profile and an adapted dust cap for enhanced all round dispersion and better synchronization with the mid-tweeter range
Tweeter
  • High-end dome tweeter with a particularly wide surround for optimised dispersion characteristics at frequencies above 20 kHz
  • Particularly lightweight cone construction consisting of semicrystalline polymer (PTFE) for maximum efficiency
  • Solid aluminium front panel with computer-optimised sound guide
  • Copper cap-optimised drive system for minimum distortion
  • Generous ventilation of the magnet system with low natural resonance
