Definitive Technology Demand Series D17 Gloss White Tower Speaker

The Demand Series outperforms the competition its price- class with more performance in a smaller form factor.

D17 high-performance, 3-way tower speakers deliver full-range, room-filling sound and precise imaging in a modern, elegant styling

Dual integrated side-firing passive radiators produce extended low-frequency reproduction free of port noise, from a smaller enclosure design

Patented BDSS mid-range provides greater linear excursion and output that results in superior mid-range detail compared to drivers of similar size

1” annealed Aluminium dome tweeter with 20/20 Wave Alignment Lens delivers accurate, smooth highs, a wider sound stage and precise imaging

Laterally offset tweeter assembly: Reduces unwanted diffraction for a more precise centre image in music reproduction

Carbon Fibre Woofers

Carbon fibre offers greater rigidity to the cone for deeper and cleaner bass notes, while preventing cone distortion that can occur with other less rigid materials.

Patented Linear Response

Patented Linear Response Wave guide extends both on and off axis frequency response, while improving dispersion for more natural mid range timbre and more precise imaging.

Offset Tweeter Assembly

A unique sonic signature feature of the Demand Series, the tweeter is offset to deliver a more precise centre stereo image and eliminate undesirable symmetric diffraction off the corners of the front baffle.

Alignment Lens Tweeter

Delivering a clear, precise high frequency response. The 20/20 Wave Alignment Lens smooths high frequencies off the tweeter for improved dispersion and a rich and balanced listening experience anywhere in your room.

Patented BDSS Driver

The patented mid-range drivers provides greater linear excursion and output that results in superior mid range detail and punchier bass compared to drivers of similar size. A 6.5“ driver equals an 8“ driver of other speakers in the price range.

Dual Passive Radiators

The Definitive Technology Engineers have 30 years of accumulated knowledge in bipolar speaker configurations, now applied to the Demand Tower speakers. Dual integrated side-firing passive radiators produce extended low-frequency reproduction free of port noise, from a smaller enclosure design.
