Definitive Technology D17 Features:

  • D17 high-performance, 3-way tower speakers deliver full-range, room-filling sound and precise imaging in a modern, elegant styling
  • Patented BDSS™ mid-range provides greater linear excursion and output that results in superior mid-range detail compared to drivers of similar size
  • Laterally offset tweeter assembly: Reduces unwanted diffraction for a more precise center image in music reproduction
  • 1” annealed aluminum dome tweeter with 20/20 Wave Alignment Lens™ delivers accurate, precise, smooth highs, a wider sound stage, and precise imaging

Flagship Performance

D17 tower speakers are meticulously engineered with a laterally offset 1” annealed aluminum dome tweeter, a 6.5” BDSS™ midrange woofer, and dual 6.5” carbon fiber bass woofers complemented by dual 10” side-firing passive radiators for a full-range, breathtakingly musical sonic performance.

Clear, Precise Highs

 

The D17 couples a laterally offset 1” Aluminum Dome Tweeter with our 20/20 Wave Alignment Lens™. We offset the tweeters by 5°, minimizing wave cancellations off the front baffle to deliver a more precise center stereo image and ensure clear, exacting high-frequency performance and detailed soundstage.

Dual 10″ Passive Bass Radiators for visceral bass response

Twin integrated 8” passive bass radiators in each speaker produce extraordinary low-end extension for louder, lower, unforgettably clean bass performance.

Audiophile-Quality Crossovers for beautifully balanced audio

Demand Series crossovers are built with the latest premium audiophile-quality parts, including polypropylene metal-film capacitors and air-core inductors. These high-end components meticulously manage frequencies for clean and crystalline treble, refined and articulate midrange, and linear, low-distortion bass. This ensures that every detail comes through within a clear, balanced presentation that never sacrifices power.

Linear Response Waveguide™ for natural imaging

Our patented Linear Response Waveguide™ extends both on-axis and off-axis frequency dispersion for more natural midrange timbre and precise imaging.

Masterful Movie Sound

True audio enthusiasts are obsessive about all sound, not just their music. The meticulous attention to detail that enables the D17 Tower Speaker to beautifully reproduce music also enables it to flawlessly reproduce home theater audio.
