3-Way Configuration with Dual 10" Passive Radiators 

The Demand D17 tower speakers feature an exclusive 3-way driver configuration with a 1” annealed aluminum dome tweeter, a 6.5” BDSS™ midrange woofer, a dual 6.5” carbon fiber bass driver complement with a dual 10” side firing passive radiator configuration for a full range, room-filling sonic performance.

1" ANNEALED ALUMINUM DOME TWEETER 

WITH 20/20 WAVE ALIGNMENT LENS™ AND LATERALLY OFFSET TWEETER ASSEMBLY

Definitive Technology sets the standard of minimalist, thoughtful design that serves to better the sound. Proper tweeters must excel in three ways: they must be stiff, light, and well-damped in order to minimize their material characteristics that will affect high-frequency reproduction. Aluminum is naturally stiff and lightweight, meeting the first two requirements. To achieve the third, Definitive Technology tweeters undergo an annealing (heat treating) process to shape and soften the material, thereby providing the necessary material damping.

Coupled with the 20/20 Wave Alignment Lens™, Definitive Technology 1” aluminum dome tweeters deliver a clear, precise high frequency response and 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. 

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

BDSS™ Midrange/woofer

Balanced Double Surround System

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

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.  

Newly Designed Carbon Fiber Woofers

This new addition to the sonic signature of the Demand Series tower features a dedicated woofer section for low frequency reproduction. Carbon fiber offers greater rigidity to the cone for deeper bass notes, while preventing cone distortion that can occur with other less rigid materials. Carbon fiber is a strong but light material, ideal for sound reproduction. It ensures that the woofers are sturdy yet light, able to handle higher excursion without deforming and provides deeper, clean low frequency.

Extruded Aluminum Front Baffle

Clean, beautiful modern industrial design with an extruded Aluminum front baffle bead blasted finish that provides a timeless look and feel that fits any décor. Lightweight, durable and recyclable, aluminum is truly the metal of a modern lifestyle.

Premium Hi-Fi Crossover

Demand Series crossovers integrate the latest in design and premium Hi-Fi quality parts. Polypropylene metal-film capacitors and air-core inductors deliver low distortion, high-clarity circuits for the circuits for the tweeter, and signal linearity for the low frequency reproduction, without compromising the midrange.

Designed in California 

Our Design Studio is located in California, where technology and innovation meet entertainment. It goes beyond the idea of a centralized location — it’s a cultural mindset that’s the Definitive Technology wellspring for creativity and inspiration.
