Definitive Technology Demand Series D7 Piano Black Bookshelf Speakers - MFAA

Definitive Technology Demand D7 high-performance bookshelf speakers deliver full-range, room-filling sound and precise imaging in a modern, elegant styling. Featuring technology advancements to both our aluminum dome tweeter and mid-range/woofer sections, each speaker delivers an unrivaled sweet spot, smoother high-frequency reproduction, and three-dimensional imaging for the most technically-advanced, premium bookshelf listening experience.

Key Features:

  • 1" Aluminum Dome Tweeter with 20/20 Wave Alignment Lens™
  • Laterally Offset Tweeter Assembly
  • BDSS™ (Balanced Double Surround System) Midrange/woofer
  • Linear Response Waveguide™


  • 1" Aluminum Dome Tweeter with 20/20 Wave Alignment Lens and Laterally Offset Tweeter Assembly
    Coupled with our new 20/20 Wave Alignment Lens™, our annealed aluminum dome tweeter delivers smoother high frequency response and improved dispersion for a rich and balanced listening experience. Offsetting the tweeter by 5° delivers a more precise center stereo image by eliminating undesirable symmetric diffraction off the corners of the front baffle
  • Extruded Aluminum Front Baffle
    Clean, modern industrial design with a bead blasted finish provides a timeless look and feel that fits any décor
  • Linear Response Waveguide™
    Patented Linear Response Waveguide extends both on and off axis frequency response, while improving dispersion for more natural mid-range timbre and more precise imaging
  • BDSS™ Midrange/Woofer
    Patented Balanced Double Surround System (BDSS) midrange/woofer provides greater excursion and output that results in superior mid-range detail and punchier bass compared to drivers of similar size
  • Demand Elegance
    Each cabinet is hand-crafted to blend seamlessly with your lifestyle—meticulously sanded, painted with five layers of premium black gloss paint, then buffed for a near-mirror finish (Level 6) for an uncompromising look in your home
  • Bass Port
    Bass port in each speaker provides superior low-end extension by smoothly transitioning air flow from the speaker into your listening area for deep, extended bass impact while minimizing turbulence and distortion
  • Annealed Aluminum Dome Tweeter
    Our annealed aluminum tweeters are precision engineered to articulate nuance and detail in the high-frequency bands for a crystal-clear listening experience
  • Acoustically Transparent Magnetic Grille
    The included acoustically transparent magnetic black speaker grilles provide natural, uncolored sound when placed on the speaker, and remove easily when you want to enjoy looking at them fully uncovered
